Accurate NRE cost estimation is important to ensure that a PCB NRE project is completed within budget and on time.
What Are the Common PCB Non-recurring Engineering Costs ?
As a PCB design engineer, it’s important to have a comprehensive understanding of NRE (Non-Recurring Engineering) charges and tooling costs in the PCB industry. NRE costs in PCB manufacturing are divided into two categories, covering non-recurring engineering tooling costs and programming expenses. It’s worth noting that these costs are not based on the main regular cost of the NRE.
Non-recurring engineering tooling cost is unique to each customer and is added to the regular NRE cost for that particular customer. This cost covers tools that are crucial for specific customer orders, including metals, press-fits, artworks, stencils, jigs, and other important tools.
The tools used in NRE tooling are highly selective, and the expenses required for them are non-recurring. They are mainly used to design products as per customer requirements. After completing the design process, the customers receive their orders.
● Programming: In PCB manufacturing, a setup fee, also known as “programming costs,” is necessary when programming machines for producing a specific PCB. This fee covers the labor and time required to program the machines, and it is a non-recurring cost. Once the programming is completed, the contract manufacturer can use the programmed data to produce the PCBA.
To accurately calculate the NRE cost in PCB manufacturing, programming costs play a crucial role. It’s worth noting that these costs vary based on the complexity and particular needs of the PCB designs. As such, careful planning, efficient utilization of resources, and early identification of programming requirements can help to minimize the overall cost and ensure successful product launches.
● Tooling: In the PCB manufacturing process, specific tools are collected, and their costs are added up to form the NRE (Non-Recurring Engineering) cost. These tools include fixtures, metals, stencils, artwork, among others, and are made specifically for a particular product and customer. For example, solder stencils are unique and can only be used for one type of circuit board, making them like fingerprints.
Once a stencil is designed and fabricated for a specific PCB, there’s no need to make new stencils to continue manufacturing the assembly. However, the tooling cost is often the most complicated item when it comes to circuit board production as it constitutes a significant portion of the overall NRE cost.
It is essential to note that consistency is a vital factor when calculating tooling costs. Some engineers make the mistake of assuming that the PCBs involved in a project require multiple layers, leading to an overestimation of the tooling cost.
Therefore, as a PCB design engineer, careful planning, meticulous identification of project requirements, and effective utilization of resources is imperative in managing the tooling cost.
Strategies for Minimizing PCB NRE

What Is Radio Frequency Identification(RFID)?
Radio Frequency Identification (RFID) is a wireless communication method that utilizes electromagnetic or electrostatic coupling in the radio frequency range of the electromagnetic spectrum. This process uniquely identifies an item, animal, or person and has the capability to track their location. Essentially, RFID search, identifies, tracks, and communicates with objects and individuals via radio frequency transmissions.
RFID is a technology that retrieves data using digital encoding from an RFID tag, and this information can be read using a reader. During this process, the device functions as a tag or label that is readable by a reader. Unlike traditional barcodes and QR codes, RFID functions by transmitting information wirelessly and through the internet. RFID can be applied using either passive or active methods and provides the ability to read from a concealed location. The collected data is then stored in a database for later retrieval.
Radio-Frequency Identification (RFID): Types
There are two types of such tags:
Active RFID
The apparatus comprises radio frequency identification (RFID) tags that are powered by a connected power supply for transmitting a signal. Concurrently, the apparatus also incorporates an antenna to facilitate the reception of data.
In the case of an active tag, it employs a dedicated power source such as a battery to enable autonomous operation without requiring energy from the source or reader. Therefore, the active tag’s circuitry can operate continuously without the dependence on external power supply, manifesting a self-dependence on its own specialized power source.
Passive RFID
Passive RFID tags, unlike their active counterparts, are not designed with an independent power supply and instead rely on power from the reader. The RFID tags integrated within this apparatus do not have a direct connection to a power supply, and passive RF tags store their energy and utilize it when exposed to emitted power from active antennas and RF tags. Such power is transmitted over specific frequencies as per standards, with low frequency utilizing the 125-134 MHZ range, high frequency employing the 13.56 MHZ range, and ultra-high frequency using the 856 MHZ to 960 MHZ range.
Unlike barcodes, RFID tags do not require direct line-of-sight with the reader and thus can be embedded into the item under surveillance. This enables Automatic Identification and Data Capture (AIDC) through the use of RFID technology.
How Does RFID Work?
Automatic Identification and Data Capture (AIDC) encapsulates several technologies, which includes radio frequency identification (RFID). AIDC techniques, utilizing radio waves, automate the identification of items, extract data, and seamlessly feed the collected information into computer systems with minimal or no human intervention. The primary components of an RFID system are an RFID tag (smart label), an RFID reader (interrogator), and an antenna.
An RFID tag features an integrated circuit and an antenna that facilitate the transmission of data to the RFID reader. Upon capture, the radio waves are converted to an easy-to-use data format by the reader. The data accumulated by the tags is accessed via a communications interface and transmitted to the host computer system. Here, it gets stored in a database for future retrieval and analysis.

Printed circuit boards (PCBs) are an essential part of many electronic devices, from smartphones and laptops to medical equipment and automotive systems. PCBs can be complex and expensive to design, so some companies or individuals may opt to try to clone an existing PCB instead of designing a new one from scratch. PCB cloning involves analyzing and reproducing an existing circuit board, so it looks and works the same as the original. Cloning can be a cost-effective way to produce additional copies of a PCB design, but it is important to be aware of the potential legal and ethical issues surrounding PCB cloning.
In this article, we will explore the process of PCB cloning and discuss some of the considerations that should be taken into account before embarking on a PCB cloning project.
What Is PCB Clone ?
PCB clone, also referred to as PCB duplication or PCB duplicate, involves using reverse engineering technology to create an exact copy of an existing printed circuit board. The process typically entails two steps – creating the Bill of Materials (BOM) and duplicating the schematic diagrams of the original circuit board, as well as understanding the design parameters and manufacturing protocols. You are not required to provide PCB Gerber files, as electronic specialists will analyze the files to deduce the PCB’s design and generate a replica board.
By using PCB cloning, the original PCB board can be replicated and installed in an electronic device, thereby eliminating the need to design and fabricate new circuit boards from scratch. This means that you can copy the entirety or a percentage of the printed circuit boards without affecting their performance, thus providing you with enhanced flexibility and the ability to produce infinite boards as per your preferences.
Moreover, electronic manufacturers can utilize the PCB clone method to streamline labor, cutting down on the amount of time and money spent in redesigning circuit boards. Furthermore, it allows replacement of electronic components that are no longer operating efficiently. Reverse engineering is a vast improvement compared to traditional manufacturing methods, thereby making the PCB clone process highly beneficial for the contemporary electronic industry.

How Many Steps Clone PCB Boards ?
The process of cloning a PCB is a streamlined and automated operation that requires specific tools and components.
Before commencing the PCB cloning process, it’s crucial to have a Bill of Materials (BOM) and a copy of the circuit schematics. Additionally, you need to select a research method that suits your specific requirements from a wide range of options.
In terms of tools, it’s necessary to have an AutoCAD program, a computer, a scanner, and a PROTEL99 to streamline the process of PCB cloning. These essential tools ensure that the method of reverse engineering is carried out efficiently and effectively, delivering precise PCB replicas that function seamlessly.
PCB Clone Steps
The process of cloning a PCB involves a series of specific steps that require attention to detail and accuracy to achieve optimal results.
When cloning, the actions listed below should be followed in order:
● Initially, you must remove all active components from the PAD hole and the tin, followed by cleaning the board using an ultrasonic cleaner. Afterward, place the empty board on the scanner and scan it horizontally, ensuring that the brightness and contrast settings are correct for viable image quality.
● The next step is to import the scan into Photoshop, where both bottom and top screen-printing techniques are comparable. Buff the surface of both top and bottom layers of the board using paper yarn and then use Photoshop to perform a color sweep across both layers.
● At this point, it’s necessary to adjust the brightness, lightness, and contrast of the image to check for clear image lines. If the image is unclear, either restart the process or utilize Photoshop to adjust the sketch. If the image is clear, save it as a black and white BMP file.
● The BMP files must then be converted into a PROTEL file using PROTEL99, followed by generating two levels using the PROTEL file. Open both imported CAD files and using the image of the PCB as a reference, transfer the component package into the CAD program, position the pads and vias in the appropriate locations and measure the pads’ outer and inner dimensions.
● Next, draw a line on the TOP Layer to install the device, erase the silk layer, convert the PCB to PROTEL, combine the two diagrams into one, and print both layers onto transparent film in a 1:1 ratio. Position the film over the board and check for any errors.
● Finally, test the cloned PCB to ensure it functions like the original. Please note that cloning a PCB requires expert attention to detail and accuracy, and alternatively can be carried out by a professional PCB clone service provider. At JarnisTech, we offer top-quality PCB cloning services that guarantee superior results and customer satisfaction.

This is the ideal resource if you are seeking expert guidance on the aspect ratio of printed circuit boards (PCBs).
The aspect ratio is a vital concern in the design of PCBs, as it affects both the functionality and manufacturability of the board. High aspect ratios may impede the drilling of holes or production of vias, potentially compromising the overall performance of the board. Conversely, low aspect ratios may restrict the number of components that can be placed on the board.
In this article, we will provide a detailed explanation of PCB aspect ratios, including their significance in PCB fabrication. Please read on for a comprehensive overview.
What is Aspect Ratio in PCB Design ?
The aspect ratio in PCB design refers to the ratio of a printed circuit board’s thickness to the diameter of its drilled holes. In other words, it is the relationship between the drilled hole size and the thickness of the board material.
Aspect ratio is an important consideration in PCB design because it can affect the PCB’s reliability, manufacturability, and performance. High aspect ratios, where the ratio of the drilled hole diameter to board thickness is larger, can be more challenging to produce reliably and cost-effectively. Therefore, it is essential to carefully design PCBs with appropriate aspect ratios to achieve desired performance and functionality while also ensuring manufacturability.
Importance of Aspect Ratio in PCB Design
The aspect ratio is an essential consideration in PCB design because it can impact several aspects of the PCB’s performance and manufacturability. Here are a few reasons why aspect ratio is important in PCB design:
● Reliability: PCBs with an inappropriate aspect ratio can lead to reliability issues such as breakage or delamination during processing or in the field.
● Signal integrity: High aspect ratio PCBs can cause impedance mismatches, signal attenuation, and other problems that can degrade signal integrity.
● Manufacturability: PCBs with high aspect ratios can be more challenging to manufacture, especially in terms of drilling small holes.
● Cost: High aspect ratio PCBs are generally more costly to produce due to the added complexity and potential for errors during manufacturing.
● Space constraints: A PCB with a larger aspect ratio can allow for greater trace density while still maintaining clearance spacing, which is especially important for miniaturized electronics where space is limited.
As a result, selecting an appropriate aspect ratio for a PCB design is crucial to achieving desired performance, reliability, and manufacturability while also minimizing costs and maximizing use of space.
How Do You Calculate PCB Aspect Ratio ?
Calculating the aspect ratio of PCB vias is of utmost importance, regardless of whether you are creating an image, a video, or any other creative work. Typically, statistical methods are employed to determine the specifications of this calculator. The aspect ratio is the ratio that establishes how high graphic objects, pictures, or films should be and how wide they must be. It can be found in the formula for aspect ratio.
Although various aspect ratios may be available for height and length dimensions, the ratio value is typically scaled down to the lowest acceptable ratio that suitably accommodates all types of media.
Here are a few ways in which aspect ratio could be utilized in PCB:
As a PCB manufacturer, we understand that the aspect ratio is a crucial characteristic in the production of printed circuit boards.
● In the first example, a board thickness of 62 mils and a hole diameter of 31 mils result in an aspect ratio of 2:1.
● The second example achieves an aspect ratio of 8:1 through a board thickness of 64 mils and a drilled hole width of eight mils.
● The third scenario involves a board thickness of 80 mils, producing an aspect ratio of 10:1, and utilizing a drilled hole diameter of eight mils.
It is important to note that a higher aspect ratio leads to a greater need for plating, which in turn increases the risk of cracking due to expansion during the PCB assembly phase. Therefore, to promote stronger vias and improved electrical connections, lowering the aspect ratio is necessary. A lower PCB aspect ratio ensures more consistent plating throughout the vias, which contributes to a higher level of durability throughout the entire lifespan of the printed circuit board.

JarnisTech Capabilities of Laser Ablated Microvias
For through-hole vias, an AR 8:1 maximum is recommended, as stated by the design guidelines found in the IPC-2221A and IPC-222 documents. A minimum drill diameter of 0.20 millimeters is recommended for use with a standard PCB thickness of 1.60 mm. At JarnisTech, however, we can achieve a density of 10:1 and 12:1 for through-hole boards, as well as a density of 0.75:1 and 1:1 for microvia HDI PCBs.
These parameters are highly suggested by JarnisTech and are completely appropriate for use in PCB manufacturing. In order to meet the high dependability standards of IPC Class 3, requirements like these are necessary. It is not possible to unilaterally reduce the size of the via pad or the hole diameter since there are considerations related to reliability.
Factors Influencing PCB Aspect Ratio
Printed circuit boards (PCBs) are a crucial component in many electronic devices, providing a base for the mounting of various electrical parts. During the design and fabrication of PCBs, careful consideration must be given to the aspect ratio of the board as it can significantly impact the performance and reliability of the final product. In this section, we will explore the various factors that influence aspect ratio and their impact on the PCB design and manufacturing.
● Density and Size of Components: The size and density of components on a printed circuit board (PCB) can also have an impact on its aspect ratio. A greater density of smaller surface mount technology (SMT) components on a PCB can lead to less expansive aspect ratios. Conversely, using larger through-hole components necessitates larger vias and holes, which may limit the aspect ratio.
The component density on a PCB can also influence the aspect ratio. High-density printed circuit boards (PCBs) contain numerous components in a small area, necessitating smaller holes and vias. This can result in less desirable aspect ratios since the thickness of the PCB places a constraint on the depth of holes or vias.
● PCB Layer Count and Thickness: The aspect ratio of a printed circuit board (PCB) is primarily influenced by its thickness and layer count. Calculating the aspect ratio of a PCB involves dividing its thickness by the smallest hole’s diameter. As the PCB thickness increases, its aspect ratio reduces, and vice versa.
The layer count of a PCB can also impact its aspect ratio, with multi-layer PCBs typically featuring lower ratios. These PCBs possess more than two layers of conductive material that sandwich insulating layers, which limit the maximum drill depth achievable in the holes or vias.
● PCB Fabrication Process Capabilities: The manufacturing process utilized in making a PCB can also impact its aspect ratio significantly. Different manufacturing techniques offer varying capabilities when it comes to creating PCBs with varying aspect ratios. For instance, the drilling and plating process used to create holes or vias on a printed circuit board (PCB) can impact its aspect ratio.
Typically, mechanical or laser drilling is employed by PCB manufacturer to create holes or vias on a PCB. Mechanical drilling is utilized for larger holes and vias, whereas laser drilling is used for smaller ones, resulting in reduced diameter holes and vias and subsequently smaller aspect ratios.
The plating method used to generate the conductive layer within the holes or vias also has an influence on the aspect ratio. Electroless plating is the preferred choice for smaller holes and vias, while electroplating is employed for larger holes and vias. Electroless plating provides a more uniform and consistent plating layer within the hole or via, which can lead to a higher aspect ratio.
How the Aspect Ratio Affects the Design and Manufacturing of PCBs ?
The aspect ratio of a printed circuit board (PCB) affects both its design and production process. A larger aspect ratio allows for deeper holes or vias, which can increase the device’s mechanical stability and thermal efficiency, resulting in a more reliable and sturdy design. However, a high aspect ratio can make the manufacturing process more challenging, requiring greater precision during drilling and plating operations.
Producing PCBs with a high aspect ratio can be a time-consuming and costly process. Achieving high-quality holes and vias requires additional effort during drilling and plating, potentially leading to higher fault rates and lower yields. This can increase production costs and extend lead times.
Therefore, it is necessary to carefully consider the aspect ratio and its potential impact on the production process during PCB design. Appropriate design adjustments can help to balance the aspect ratio with the production feasibility, ensuring that the aspect ratio is conducive to the PCB’s normal production.
So, How to ensure that the aspect ratio is conducive to the normal production of PCB?
● Communication with the Manufacturer: To ensure effective PCB manufacturing, it is crucial to maintain open communication with the manufacturer throughout the design process. This enables early identification of any manufacturing concerns and facilitates design revisions that can improve the product’s manufacturability.
Furthermore, it is important to have a comprehensive understanding of the manufacturer’s capabilities and constraints in designing printed circuit boards (PCBs). PCB manufacturers’ capabilities may vary in terms of aspect ratios, making it necessary to select a manufacturer capable of meeting the design specifications.
Designers must also consider the tolerances and requirements necessary for the holes and vias on the PCB to ensure the desired aspect ratio.
Additionally, designers should rely on design guidelines and principles to ensure that the PCB design meets the minimum criteria for drilling and plating. Such guidelines can prevent common manufacturing problems, including breakout and burrs. Maintaining open communication with the PCB manufacturer and following design principles can help achieve efficient and effective PCB manufacturing.
Impact of Aspect Ratio on PCB performance
The impact of aspect ratio on PCB performance includes:
● Signal Losses: Higher aspect ratio vias may have increased parasitic capacitance and inductance, leading to higher signal losses and decreased signal quality.
● Electrical Reliability: High aspect ratio vias may have insufficient plating thicknesses leading to open circuits, decrease in reliability or electrical performance degradation.
● Thermal Management: High aspect ratio vias impede the flow of heat in a PCB, which can lead to thermal management problems such as hot spots, uneven temperature distribution, and decreased reliability of components.
● Manufacturability: The aspect ratio of a via can impact manufacturability, which can affect the yield, cost, and production speed of PCB manufacturing.
● Design Flexibility: Low aspect ratio vias offer more design flexibility which can be preferable in some situations, but high aspect ratio vias are needed for some designs where a larger distance must be covered between layers.
Therefore, the aspect ratio of vias is an important consideration in PCB design and has a significant impact on both electrical performance and manufacturability of printed circuit boards.
Challenges in Achieving High Aspect Ratio
Achieving high aspect ratios in PCB design can be challenging due to a number of factors, such as:
● Drilling limitations: Drilling small holes with high aspect ratios can cause drill bits to break or wear out quickly, increasing the risk of errors and inaccuracies in the PCB design.
● Plating issues: Plating the inside of small, high aspect ratio holes with copper can be difficult, leading to incomplete plating or voids that may affect the performance of the PCB.
● Lamination challenges: Getting the copper layers to adhere properly during the lamination process can be tricky when dealing with very thin traces and tight spaces between them.
● Etching difficulties: Etching small, high aspect ratio traces can be difficult because the acid doesn’t always flow evenly into the narrow spaces.
● Signal integrity: High aspect ratios can create impedance mismatches, signal attenuation, and other problems that can degrade signal integrity.
Advanced Techniques for Maintaining Aspect Ratio
here are several advanced techniques for maintaining aspect ratio in high-density PCB designs:
● Laser drilling: Laser technology allows for precise drilling of small holes with high aspect ratios, which can minimize breaking or wearing of drill bits and reduce errors in the PCB.
● Sequential lamination: In this process, the laminate material is built up one layer at a time, allowing for more precise control of the thickness of each layer and ensuring better adhesion of the copper layers.
● Resin-coated copper (RCC):RCC is a process in which a resin coating is applied to the copper layer before drilling to provide reinforcement and prevent delamination.
● Plasma etching: Instead of using traditional acid etching, plasma etching employs charged gas molecules to create a highly controlled and more uniform process for etching small, high aspect ratio traces.
● Staggered drilling: Staggered drilling involves drilling holes in alternating locations in adjacent layers, which can reduce the aspect ratio by allowing for larger holes to be drilled in some layers.
By using these advanced techniques, it is possible to achieve the high aspect ratios necessary for miniaturized, high-density PCB designs while also maintaining high levels of performance, reliability, and manufacturability.
How to Choose the Right Aspect Ratio for Your PCB Design ？
Choosing the right aspect ratio for your PCB design involves several factors, including the size and complexity of the board, the number and size of components, and the performance and cost requirements of the final product. Here are a few steps to help you choose the appropriate aspect ratio for your PCB design:
Determine the size of the board and the number and size of components that will be used. This will help you determine the general thickness of the PCB.
Consider the pitch between components on the board and any other spacing requirements. This will help you determine the minimum drill size.
Check with your PCB manufacturer to determine their capabilities for drilling and plating small holes with high aspect ratios.
Calculate the required aspect ratio by dividing the board thickness by the minimum drill size. The recommended aspect ratio is typically between 8:1 and 12:1 to ensure proper plating and adhesion.
Consider any signal integrity issues that may arise with high aspect ratio designs. For high-speed applications, it may be necessary to adjust the aspect ratio to ensure proper signal integrity.
By carefully considering these factors and working closely with your PCB manufacturer, you can select an appropriate aspect ratio for your PCB design that balances performance, reliability, and manufacturability.
Summary
Aspect ratio is an essential consideration in PCB design as it influences the manufacturability, reliability, and performance of the printed circuit board. The aspect ratio of a PCB represents the relationship between its thickness and the diameter of its drilled holes, and choosing the right aspect ratio involves balancing numerous factors such as the size, complexity, and intended use of the PCB. Advanced techniques such as laser drilling, sequential lamination, RCC, plasma etching, and staggered drilling can help to overcome the challenges associated with high aspect ratio designs. Therefore, designers must carefully consider aspect ratio when developing PCB designs to ensure efficient and effective manufacturing, reliable performance, and optimal use of space.
PCB manufacturers considering reducing the aspect ratio of their circuit boards must keep in mind the board thickness and minimum drill diameter. Failing to do so can lead to manufacturing roadblocks and delays. Lowering the aspect ratio can result in stronger vias and larger connection areas for components.

Since then, PLDs, including FPGAs, have undergone significant improvements in terms of functionality and performance. As such, it is worth delving into the specifics of FPGAs and the advantages they offer.
What Is FPGA ?
The Field Programmable Gate Array (FPGA) is a versatile type of integrated circuit that can be adapted to suit the unique needs of a specific application by utilizing user-programmable interconnects within its hardware blocks. An FPGA can facilitate the implementation of new functionalities throughout its lifespan due to its ability to reprogram its interconnects.
The design of FPGAs owes its origins to earlier devices like programmable read-only memories (PROMs) and programmable logic devices (PLDs). Though both PROMs and PLDs could be programmed either at the factory or in the field, their configurations were permanent and unalterable since they relied on fuse technology. However, FPGAs store their configuration information in reprogrammable mediums like static RAM (SRAM) or flash memory, offering greater flexibility.
Industry giants such as Intel, Lattice Semiconductor, Microchip Technology, and Microsemi are among the top manufacturers of FPGAs.
FPGA Architecture and Components
FPGA (Field Programmable Gate Array) consists of several architectural and component elements that enable users to program the circuit according to the required functionality. Here are some of the main architectural elements of an FPGA:
● Configurable Logic Blocks (CLBs): These are the basic building blocks of FPGAs, consisting of lookup tables (LUTs) for combinational logic, and flip-flops for sequential logic. In addition, some modern FPGAs have built-in math operations units, which come in handy for DSP applications.
● Programmable Interconnect: The interconnection gives the CLBs the tunnels through which data passes and by which signals from input and output pins are connected to the LUTs and flip-flops. In modern FPGAs, the interconnect uses a hierarchy of different types of routing wires, each with different speeds, directions, and lengths.
● Input/Output Blocks (IOBs): IOBs allow external signals to communicate with the internal CLBs and perform parallel or serial interfacing with other digital circuits/systems. The IOBs can handle a combination of single-ended, voltage-regulated, or differential signals and external clock signals.
● Embedded Memory Blocks: Some FPGAs have embedded memory blocks such as block RAM or FIFO buffers, available for designers to use either as a standalone memory or as an interconnection medium between modules.
● Digital Signaling Processing (DSP) Blocks: DSP blocks in the FPGA consist of multiple arithmetic circuits for performing complex math operations such as multiplication, division, and addition efficiently.
● Clock Management: FPGAs can offer various clock methods to ensure reliable and jitter-free clocking of internal modules or to connect to external synchronization requirements.
● Configuration Memory: The FPGA configuration information is stored in non-volatile memory such as Flash, ferroelectric, electrically erasable programmable read-only (EEPROM), or volatile Static RAM (SRAM), which will configure the FPGA at each start-up.
The interconnection between all these elements is programmable after manufacturing, allowing FPGA devices to provide a unique flexibility of configuration according to the intended application domain.

Programming an FPGA involves describing the desired hardware functionality in a hardware description language (HDL), compiling the HDL code into a configuration bitstream, and then loading the bitstream into the FPGA. The general steps in programming an FPGA are:
●Design Entry: Write the hardware functionality in a HDL such as VHDL or Verilog, which describe the FPGA’s hardware behavior.
●Synthesis: The HDL code is translated into an optimized netlist, where the synthesis tool configures the FPGA with the desired functionality. This step creates a structural representation of the logic.
●Mapping:Mapping the synthesized netlist onto the FPGA architecture specified in the design.
●Placement: Placement of synthesized logic blocks on the FPGA floorplan that maximizes performance and timing.
●Routing: Creation and optimization of the interconnects, to connect the placed blocks together and to the input/output pins.
●Timing Analysis: Timing Verification and analysis to ensure the design timing requirements are correct.
●Bitstream Generation: Generation of a binary data file containing instructions for configuring the FPGA, known as “bitstream.”
●Configuration:Download the bitstream onto an FPGA device to configure the FPGA according to the specified design.

Hardware description languages, such as VHDL and Verilog, offer a highly structured way of describing the behavior of digital systems and are used to create complex systems spanning a range of industries. FPGAs can also be programmed using high-level programming languages, such as C and C++, with the help of hardware design libraries such as High-Level Synthesis (HLS).
How FPGAs Work ?
FPGAs or Field Programmable Gate Arrays are integrated circuits that can be programmed or configured to perform specific tasks after manufacturing. Here is a high-level description of how FPGAs work:
● FPGA design: The first step is to create a design using a hardware description language (HDL) such as Verilog or VHDL. The design is usually created using a computer-aided design (CAD) tool.
● Synthesis: Next, the design is synthesized to produce a netlist, which is a high-level representation of the circuit.
● Place and Route: The place and route process takes the netlist and maps it onto the physical resources of the FPGA, including logic cells, routing switches, and input/output pins.
● Configuration: Once the netlist has been placed and routed, the FPGA must be configured with the appropriate settings using configuration memory such as flash memory or SRAM. This step sets the electrical path, logical connection and creates the interconnects between the devices.
● Operation: After configuration, the FPGA performs the programmed function and can be updated with new functions by reprogramming the configuration memory.
FPGAs can be reprogrammed repeatedly and can execute parallel operations as well as displaying lower power consumption in comparison to alternatives.
Why You Use a Field Programmable Gate Array ?
With FPGAs, you can tune your chip such that it can handle a high workload. So, when working with these chips, you may acquire the best possible outcomes. In addition to this, FPGA enables you to make later modifications at the chip level to produce the outputs that you want. Because of this level of adaptability, you are able to make significant modifications. For instance, you can adjust the power and memory use of your machine by making use of FPGA in order to save up on resource utilization. That could end up being a savior for your device in the end.
When it comes to the prototype of ASICs (Application-Specific Integrated Circuits) or Processors, FPGAs can prove to be quite helpful. This is due to the fact that you are able to re-program an FPGA until you obtain a final, bug-free Processor or ASIC that you are able to mass produce.
Comparison of FPGAs with Other Types of Programmable Logic Devices
FPGAs are one type of programmable logic device, and there are several other types available as well. Here is a comparison of FPGAs with other types of programmable logic devices:
● CPLDs (Complex Programmable Logic Devices): CPLDs are smaller and slower than FPGAs and generally used for simpler designs. They usually have a fixed architecture with a limited number of programmable elements.
● PALs (Programmable Array Logic): PALs are an early type of programmable logic device, and they have a fixed number of inputs and outputs. The logical functions are implemented using a programmable AND array followed by a fixed OR array.
● GALs (Generic Array Logic): GALs are similar to PALs, but they have additional programmable features such as flip-flops and control circuits, thus being more flexible than PALs.
● ASICs (Application-Specific Integrated Circuits): ASICs are custom-designed integrated circuits that are optimized for a specific application. They typically have higher performance and lower power consumption than FPGAs, but are more expensive and have longer design time.
Compared to CPLDs, PALs, and GALs, FPGAs are larger, faster, and more flexible. They offer a large number of programmable logic elements, optimized routing, and other features that allow designs to be implemented in a more optimized way. When compared with ASICs, FPGAs are more flexible at design time, provided design modifications are quicker and can be tested easily.
ASIC Vs. FPGA
Choosing between ASICs and FPGAs requires a thorough evaluation of each technology’s unique benefits. Numerous comparisons between the two types of technologies are available online. Historically, FPGAs were more suitable for designs with lower levels of complexity, speed, and overall volumes. However, modern FPGAs are capable of achieving performances of up to 500 MHz and beyond while boasting significant improvements in logic density, embedded processors, clocking, high-speed serial, and DSP blocks at increasingly affordable prices. As a result, FPGAs have become an attractive option for a broad range of designs.
Compared to microprocessors like ASICs, FPGA designs offer three significant advantages, particularly for prototypes or limited production runs. These advantages include:
●Performance of Flexibility: FPGAs are not often utilized in heavily parallelized processes due to the inability to match the performance of CPUs. Applications such as large image processing and digital signal processing require numerous cores and out-of-order instructions that current microprocessors execute better.
Furthermore, FPGA designs can incorporate several hard or soft microprocessors working together in a single chip. This integration eliminates the need to physically connect two separate devices, thus reducing the required space for the design.
FPGA design cycles require less manual intervention and are easier to manage due to their simpler nature. Routing, positioning, and timing are often handled automatically by the software to ensure compliance with specified criteria.
●Reusability: The versatility of FPGAs as reprogrammable and reusable devices makes them highly adaptable for rapid prototyping, with minimal costs associated with design mistakes or modifications.
FPGAs have a distinct advantage over ASICs due to their reconfigurable capability. Once the system has been established, FPGAs offer the ability to reconfigure repeatedly, enabling further modifications, optimization, and customization that ASICs cannot achieve. This capability is despite an intricate and detailed IP core design for a specific application. The true value of FPGAs lies in their reprogrammability, which provides PCB design engineers with increased flexibility for future design iterations and modifications.
●Quick Acquittance: FPGAs offer a shorter time-to-market advantage because they are not pre-designed for specific activities. After purchasing an FPGA, it can be configured to fit the required design specifications. This flexibility is valuable for PCB design engineers, as they can potentially reduce development time and rapidly prototype with FPGAs, leading to a quicker time-to-market.
Programming Languages and Tools for FPGAs
There are several programming languages and tools available for designing FPGAs. Here are some commonly used ones:
● Hardware Description Languages (HDLs): HDLs like Verilog and VHDL are used to create the digital circuit designs that implement the required functions. HDL-based designs are transformed by logic synthesis tools into a netlist of primitive digital logic elements (gates, LUTs, flip-flops, etc.) and connected by logic synthesis tools into a full digital circuit design.
● High-level synthesis (HLS) tools: These tools allow designers to write code in a high-level language such as C/C++, Python or even OpenCL, which is then automatically converted into a hardware description language or a netlist-based design using various optimization criteria. This can significantly reduce design time and provide higher-level abstraction.
● FPGA Development Platforms: FPGA vendors offer development platforms, which include software for design compilation, simulation, synthesis, and debugging. They provide a comprehensive workbench for test and builds utilizing integrated development environments (IDEs).
IP Cores: Intellectual property cores are pre-built blocks of design (i.e. memory, processors, communication interfaces, etc) provided by FPGA vendors to accelerate complex designs or applications development, frequently tailored for specific uses.
● High-Level Design Tools: Commercial high-level tools such as MATLAB, Simulink, or LabVIEW provide integration with FPGA design flows to create and validate designs faster and more efficiently.
The selection of tools and languages may depend on a variety of factors such as the designer’s experience, the complexity of the design, and the specific requirements of the project.
Why an FPGA when a Microcontroller Would Do ?
Choosing between an FPGA and a microcontroller depends on whether the design requires software or hardware functions.
● A microcontroller operates by executing instructions sequentially, which imposes inherent limitations. The intended functionality must align with the available instructions, and performing multiple processing jobs at the same time is generally not feasible. Although instructions are highly flexible and can be executed at high frequencies, software-based digital design still has drawbacks.
● A hardware-based approach is an alternative. Ideally, each new design could be created with a digital IC tailored to the required system functionality. There would be no software development, no instruction set limitations, and no processing delays. The result would be a single IC with input and output pins and digital circuitry designed precisely for the required operations.
● Developing an ASIC for each board is impractical, but FPGAs offer a more practical solution that approximates the process. FPGAs provide the flexibility of reprogrammability to allow digital circuits to be modified to meet specific design requirements. This approach combines the best of both worlds by offering hardware implementation with the flexibility of software-like modifications.
Importance of FPGA

The cost of essential components is also a significant factor contributing to the high cost of PCB assembly. The fabrication and assembly of printed circuit boards (PCBs) are reliant on sophisticated technology that caters to the demands of various industries. Consequently, the cost of PCB assembly is directly dependent on the firms, products, and assembly strategies involved.
Furthermore, there are three critical aspects related to the cost of the PCB that must be considered during PCB assembly:
● High-cost raw materials can lead to increased PCB production expenses.
● Unforeseen abnormalities that arise during production necessitate retesting at every stage of the assembly process.
● The assembling process has a significant impact on both the performance and cost of the resulting PCB.
How Can I Have Professionals Reduce PCB Assembly Cost ?
The cost of printed circuit board (PCB) assembly is frequently influenced by multiple factors, including the quantity and type of components and the intricacies of the assembly process. Different PCB assembly providers may use distinct pricing methods, causing pricing variations to occur.
Despite having no control over the assembly process, specific design strategies may be leveraged to reduce the overall cost of PCB assembly. By implementing such tactics, you can achieve your cost-effective goals and successfully reduce PCB assembly expenditures.
● Putting Surface-mount Parts on Just One Side: The cost of manufacturing a printed circuit board (PCB) with surface-mounted devices (SMD) on both sides is typically higher than that of a PCB assembly with SMDs on one side. This is because the process requires only a single pick and place setup iteration, resulting in significant cost savings for the stencil.
● Proper Designator Labeling: Designators are an essential component of PCB layout as they aid in component identification on the printed circuit board. They should be positioned in proximity to the corresponding components and be easily recognizable. The inclusion of designators simplifies the setup process for PCB assemblers and reduces the likelihood of issues arising during hand placement.
● Panelize The PCB: For mass production of circuit boards (PCBs), it is advisable to produce them in panels to reduce costs and streamline the assembly process. Manufacturing multiple iterations of the same printed circuit board (PCB) in a single panel reduces the number of PCB assembly runs.
During the pick and place process, it is crucial to ensure that the PCB panels contain sufficient fiducial markers to maintain accurate orientation. Fiducial markers are visual cues that aid in effective pick and place machine operation, and their inclusion in the PCB panel is highly recommended for maintaining precision in automated assembly processes.
● Give A Full BOM List: Generating a Bill of Materials (BOM) is a critical step during PCB layout development. This step is often considered less crucial than Gerber generation; however, it holds more significance. BOM assists the assembler by enabling them to place components on the appropriate footprint. It also aids in procurement planning and budgeting by allowing optimization of quantity and usage.
Generated by a designer, BOM files are essential for PCB assemblers to acquire the correct components and materials and initiate PCB assembly. Incomplete BOM files may lead to unnecessary delays and the procurement of inappropriate components, resulting in wasted time and expenses. The BOM should include the name of the supplier and manufacturer, part number, quantity, reference designator, and details regarding the parts and package footprint.
Several PCB assemblers offer their own BOM generation forms. When completed by the designer and provided to the assembler, it leads to a faster assembly process. Moreover, designers should consider providing alternative component replacement options, including replacement part numbers on the BOM. While constructing a circuit, a specific IC package may no longer be available on the market, making finding an alternative replacement a difficult task. Providing alternatives saves the assembler’s time searching for parts that are no longer accessible, reducing delays in production.
● Adjust Order Quantity: Order volume plays a significant role in reducing the overall costs of a PCBA. In general, the cost per unit decreases as larger quantities are ordered, whereas smaller quantities result in higher per-unit costs. This holds true for both bare and populated PCBs, as well as electronic components such as ICs, resistors, and capacitors. Therefore, there exists an inverse relationship between cost and quantity or order volume.
It is crucial to ensure that the PCB assembler can deliver your required specifications while also considering your order quantity requirements. When developing prototypes in quantities of 1 to 5 pieces, the cost per piece unavoidably tends to be higher compared to bulk or higher-volume orders.
● SMT Assembly Price is Cheaper Than Through-hole Assembly: Most modern electronic production facilities utilize Automated Surface Mount Technology (SMT), as it is a cheaper production method in terms of labor cost for custom PCB board production.
While hand placement is still used for Through-Hole Technology (THT), which has been in use since the inception of the industry, it is now mostly supplanted by SMT technology. Although certain connections that are subject to heavy stress, such as power connections, may still require THT, for the most part, SMT has taken over.
It is essential to minimize the number of through-hole operations in the manufacturing process as it contributes to higher costs for custom PCB design. In conclusion, the use of SMT has become the preferred technology, owing to its cost-effectiveness in modern PCB assembly manufacturing.
● Design Complexity: In order to minimize costs during PCB assembly, it is advisable to keep the layout complexity to a minimum. Additional work for the manufacturer, required to realize elaborate designs, can increase costs. One example is ensuring that all components are located on the same side of the circuit board, avoiding the need for surface mounting twice.
However, complexity may be unavoidable in certain instances. For instance, further scrutiny may be required for the inspection of specific design elements like ball grid arrays (BGAs). Similarly, some elements like conformal coating might necessitate an additional assembly phase, despite being necessary. This coating protects mining equipment and medical instruments from dust and vibration but is unfortunately often expensive.
● Lead Time: Expedited PCB orders entail a higher cost, akin to that of the United States Postal Service. If an ECM or bare PCB boards is given a shorter turnaround time to complete the project, it will charge a higher rate. In such cases, the producer may need to source resources from within the United States instead of other countries, thereby incurring higher costs. Unfortunately, manufacturing costs in the United States are higher than those in China, as widely acknowledged.
Moreover, the choice of components influences the lead time. By specifying readily available components that are already in stock, it becomes easier for the contractor to expedite the project completion process.
● Outsourcing Your PCB Services: Many business owners mistakenly believe that assuming as many responsibilities as possible themselves can save costs. However, this DIY approach often falls short in the long run. Despite potentially spending less initially, production delays, design flaws, and other factors can increase overall costs. The equipment and materials used in-house may not match the quality that outsourcing to a professional PCB manufacturer can provide. Ultimately, partnering with a PCB manufacturer can offer access to superior tools, high-quality products, and overall cost reductions.
While managing costs is a valid concern, it should not impede PCB initiatives. Contact us today to learn more about our services.
Importance of Cost-saving in PCB Assembly Production
Cost-saving in PCB assembly production is important because it directly impacts the profitability of the final product. By reducing the cost of PCB assembly production, a company can increase its profit margin, maintain competitiveness in the market, and invest resources into research and development of new products. Additionally, cost-saving measures can improve overall manufacturing efficiency, reduce defects and production errors, and enhance the quality of the end product. Therefore, an emphasis on cost-saving in PCB assembly production is essential for long-term business success.
Conclusion
Maintaining a long-term partnership with a single PCB assembler or manufacturer is advantageous for your company. Engaging in trial and error with products from different manufacturers cannot produce consistent results. It is therefore important to foster strong mutual cooperation and trust with your PCB assembler to achieve greater goals and generate more business. This, in turn, may result in lower pricing for your orders.
It is crucial to keep in mind that the cost of PCBA for an electrical device project is just a small portion of the overall expense. While prices may vary based on the supplier and location, they are not the primary factor driving up costs.
In modern times, electronic manufacturing companies are designing increasingly complex printed circuits with multiple layers, causing a surge in the importance of PCB stackup design. It is common knowledge that a well-designed stackup is crucial for reducing radiation from PCB loops and associated connections. Conversely, a poorly designed stackup can significantly increase radiation levels, posing potential safety hazards.
The growing demand for smaller electrical goods compels companies to use PCBs with multiple layers and a three-dimensional design approach, leading to new challenges in design tactics like SMD packaging and layer stackup. As printed circuits become ever more sophisticated, with a high number of layers, the stackup or stack of PCBs has gained increasing importance in design considerations. Compared to earlier times when PCB designs were rudimentary and only served as a platform for connecting electronic components, there was minimal need for multi-layer stacking due to the simplicity of these designs.
To create highly professional and reliable systems, it is essential for electronic manufacturers to consider specific guidelines while designing stacks. Let us delve into some of these crucial guiding principles.
Definition of PCB Layer Stackup
In the domain of PCB design, the term “Layer Stackup” refers to the arrangement and configuration of the conductive and insulating layers that make up a printed circuit board prior to final board design. A PCB layer stackup is a critical aspect of the overall design process, as it determines the electrical and mechanical properties of the board and affects its performance, impedance, and reliability. The proper layer stackup is essential for achieving optimal signal integrity, power distribution, and thermal management in any PCB design.
PCB Layer Stack-Up Basics
PCB layer stack-up basics include:
● There are typically two types of PCB layers: signal layers and power/ground planes. Signal layers carry electrical signals and are routed using traces. Power/ground planes provide a low-impedance path for the flow of current and help to reduce noise in the circuit.
● Inner Layers vs. Outer Layers: Inner layers are buried within the PCB and are not visible from the outside. Outer layers are visible and can be seen on the surface of the PCB.
● Copper Weight: The thickness or weight of the copper layer impacts the current carrying capacity and impedance of the PCB. The most common copper weights are 1 oz and 2 oz.
● Prepregs:Prepregs are layers of material that provide insulation between copper layers. They are made of resin and fiberglass, and the thickness impacts the overall thickness of the PCB.
● Impedance Control:Impedance control is important for ensuring consistent signal integrity. The distance between copper layers, copper thickness, dielectric constant of the substrate material, and trace geometry all impact impedance.
Main Advantages of Stack Up
● A well-planned PCB layer stackup can significantly reduce external interference, radiation, and impedance and crosstalk issues that may arise in high-speed PCB layouts. Moreover, with a proper layer stackup, you can strike a balance between low-cost efficient production processes and preserving signal integrity, which is imperative for high-performance electronic devices.
● By selecting the appropriate layer stackup, you can improve the Electromagnetic Compatibility (EMC) of your PCB design. Considering the advantages, pursuing a stacked PCB arrangement is often a practical and advantageous choice for applications based on printed circuit boards. Therefore, it is crucial to have a thorough understanding of PCB layer stackup design principles when creating complex PCB designs to achieve optimal performance and reliability.
General layers in multilayer PCBs include the ground plane (GND plane), power plane (PWR plane), and inner signal layers. An example of an 8-layer PCB stackup is shown below.
In PCB design, the distribution of layers in a printed circuit board follows a symmetrical or balanced structure, as depicted in the diagram. Alongside the layer distribution, it is also crucial to consider the spacing between layers. To achieve miniaturization goals, trace spacing must be minimized during the layer stack-up planning process. The interlayer space can comprise either core or prepreg materials. When fabricating multilayer PCBs, one or more cores and prepregs can be used.
The cores consist of copper-plated glass-reinforced epoxy laminate sheets, with thicknesses ranging from 0.1mm to 0.3mm. PCB design engineers must take into account these factors and carefully select core and prepreg materials with the appropriate thicknesses and interlayer spacing to improve signal integrity, reduce noise, and enhance various other PCB performance metrics. Proper layer stack-up planning is vital to ensure that the PCB is optimized for efficient signal transmission and high reliability.
PCB Stackup DesignRules and Considerations
The design and construction of a PCB layer stackup has a significant impact on the board’s production and assembly. During the fabrication process, it is crucial to consider key factors such as the number of layers and their layout, as well as the type of materials used. These considerations enable a balance between thickness constraints, material parameters such as coefficients of thermal expansion, dielectric constant, electrical strength, and signal isolation.
It’s important to carefully select the appropriate through-routing option, as it can impact the overall stackup design. PCB designers must be mindful of the various parameters that influence stackup design to ensure optimal performance and reliability. Understanding these factors is essential in creating an optimized PCB layer stackup, which can result in efficient signal transmission, while also limiting noise and EMI issues. Therefore, PCB designers must pay close attention to these aspects to create a highly-functioning printed circuit board.
● Number of Layers: When planning your printed circuit board (PCB) stackup, the first factor to consider is the required number of layers. This decision should be based on factors such as the type of signals (high-speed, low-speed), power demands (high-power boards or circuits utilizing power supplies), and ground layers or planes. It is strongly recommended to avoid mixing different types of signals on inner layers. For most boards, the layer count can be calculated using the pin density.
Once the pin density has been determined, it is advisable to consult your contract manufacturer (CM) for stackup support or refer to a readily available lookup table to determine the number of signal layers and the total number of layers required. Additional information, such as the values for controlling impedance, may also be required.
By thoroughly considering these factors and leveraging the expertise of your CM or utilizing reliable lookup tables, you can achieve a well-optimized PCB stackup that meets your design requirements and ensures optimal performance.
● The number of Signal Layers: In the design of printed circuit boards, the number of signal layers required can depend significantly on the intended application of the board. For example, high-speed signal or high-power applications often require more signal layers than low-speed signal applications.
When designing complex devices with a low pitch and a large number of pins, such as ball grid arrays (BGAs), it may be essential to use additional signal layers to accommodate the increased number of required connections.
Stringent signal integrity requirements, such as extremely low crosstalk, may also necessitate an increase in the number of signal layers to ensure optimal performance.
For mixed-signal applications, the separation of analog and digital signals is typically required, which often results in an increased number of signal layers.
During the design phase, the use of a signal and power layer estimation tool can be invaluable in determining the precise number of signal layers required to meet specific design requirements. By leveraging these tools, design engineers can allocate signal layers effectively and fine-tune their circuit board designs to optimize performance and functionality.
● The Number of Power and Ground Layers: Designers can employ ground and power planes to allocate certain signal layers exclusively for routing signals. These planes also help to minimize DC resistance in the power and ground rails, leading to a reduced DC voltage drop at the devices.
The ground layer refers to the copper plane connecting to the ground connector of the power supply. On the other hand, a power layer is a flat copper plane joined to the power supply rail.
Furthermore, these planes act as high-frequency and time-varying signal return pathways, reducing noise and signal crosstalk and promoting signal integrity. Power planes also improve the circuit’s capacitive decoupling capability, reduce electromagnetic radiation, and enhance electromagnetic compatibility (EMC) performance. By leveraging these benefits during the printed circuit board design process, designers can optimize the circuit’s reliability and performance.
● Controlled Impedance Traces: A controlled impedance trace is a circuit board trace and related planes that create the characteristic impedance of a transmission line. Achieving a uniformly managed impedance is crucial for preserving signal integrity.
In cases where the reference plane is not present on the adjacent layer, another copper feature located on that layer may serve as the reference.
During the manufacturing process, it is necessary to ensure a homogeneous etch across the length of the line, including the breadth and trapezoidal effect. To meet these requirements, etching tolerances must be maintained and consistency in the etching process is critical. By paying close attention to these details, designers can achieve optimal manufacturing outcomes, resulting in a printed circuit board design that performs efficiently and reliably.
● Spacing Between The Layers: In printed circuit board design, it is crucial to maintain a close coupling between the signal and current return planes to reduce capacitance. The coupling between ground and power planes should also be maintained at a close proximity.
Regardless of which adjacent plane they occupy, signal layers must always be situated near one another. Achieving tight coupling and a suitable layer spacing is necessary for ensuring continuous signaling and overall operational efficiency. It is advisable for designers to adhere to these principles during the layout to optimize the performance and functionality of the printed circuit board.
● Trace Width and Spacing: The routing of ball grid array (BGA) packages presents a significant challenge to PCB layout. During the design process, designers must pay close attention to the breakout area and determine the number of signals that require routing between vias. This crucial step establishes the minimum trace width and spacing that should be employed.
It is of vital importance to ensure that a minimum line width is observed to avoid any potential negative impacts on signal quality. PCB designers should carefully examine the design to check for any detrimental effects that may arise with narrow trace widths and make necessary adjustments. By following these guidelines, designers can effectively address challenges associated with routing BGA packages, thereby optimizing the design of the printed circuit board.
● Layer Arrangement: When designing a printed circuit board, determining the number of layers is a crucial first step. After that, it is necessary to establish how the layers should be stacked or ordered. Here are some good ground principles to follow:
● Route high-speed on minimum thickness microstrips.
● Avoid having two signal layers adjacent to each other.
● Place signal layers next to internal power layers for tight coupling.
● Make the stackup symmetric from the top and bottom layers inward.
● Power and ground layers should have minimal spacing between them.
When designing a printed circuit board, an essential aspect of stack-up architecture is the placement of sequential layers. Before routing, designers must carefully consider the arrangement of high-speed signal layers, with placement according to microstrip thickness being a crucial element. Signal layers are often situated close to the ground or power plane, leading to tight coupling.
In addition, limiting the number of lamination steps in sequential lamination plays a critical role due to the potential for increased costs and time consumption. PCB designers must maintain a good balance between stack-up complexity and cost-effectiveness to produce an optimal board design that meets performance, reliability, and fabrication requirements.
● Determining Layer Material Types: When designing a printed circuit board, selecting materials for the layer stackup is a critical aspect that requires consideration of their thermal, mechanical, and electrical properties, as well as how they interact with one another. For signals, 0.5-ounce copper is typically employed, while 1-ounce copper is used for power planes, and 2-ounces of copper may be used for high-current applications.
Typically, printed circuit boards feature a solid fiberglass substrate core that provides the PCB with thickness and strength. Some flexible PCBs, on the other hand, may use a flexible high-temperature plastic.
The next layer in the stackup consists of a thin copper foil that is affixed to the board. In double-sided PCBs, copper is found on both substrate sides, with the thickness of the copper varying depending on the layering of the PCB stack.
A solder mask layer is applied over the copper foil to prevent the copper traces from coming into contact with other metals. This layer is crucial in aiding users in soldering to the correct location while avoiding solder jumpers.
The silkscreen layer is applied over the solder mask layer to include symbols, numbers, and letters, making it easier for humans to understand the board and facilitate assembly. PCB designers must carefully select each of these components, ensuring they are sized appropriately and function optimally, for an optimized printed circuit board.
● Determining Routing and Vias: When designing a printed circuit board, it is important to route high-speed signals on intermediary layers located between levels. This design practice enables ground planes to act as a shield, effectively containing radiation produced by fast-moving signal tracks.
When signal levels are placed in proximity to plane levels, nearby planes are able to conduct the return current, reducing the return path inductance to a minimum. With standard construction techniques, it is possible to achieve decoupling below 500 MHz, thanks to the insufficient capacitance between adjacent power and ground planes.
High-speed signals are prone to signal integrity issues, and therefore, thorough consideration must be given to PCB design principles. By keeping these aspects in mind, designers can ensure effective signal transmission, reduce noise, and enhance the reliability and performance of printed circuit boards.
Recommendations in DesignPCB stack-up
To achieve an optimal printed circuit board (PCB) stack-up design, several best practices should be followed. Firstly, it is recommended to limit the number of sequential layers to three or fewer to reduce processing time and keep costs and delivery times under control.
When using stacked vias, they should be filled after each sequential layer, which can add complexity to the manufacturing process and increase the build-up’s span. Therefore, using staggered vias can be a cost-effective alternative if the design permits.
It is crucial to know the specific layers in which mechanical buried vias will be implemented and to determine the need for staggered and buried vias. This information must be carefully considered during the stack-up design phase.
It is also worth noting that sequential lamination may not be suitable for all materials. As such, manufacturers should verify the suitability of their materials for sequential lamination during the planning stages to avoid any potential issues during manufacturing.
By following these guidelines, you can design a well-optimized PCB stack-up that is technically sound and exhibits excellent manufacturability, ensuring a successful outcome for your PCB project.
PCB Stackup Design Example
Several PCB stack-up options can be accomplished depending on how you apply the tips mentioned earlier. This reference graphic demonstrates an exemplary 10-layer PCB stack-up design that is particularly useful in PCB design projects.
In modern circuits with high operating speeds, effective PCB stack-up design is critical to optimize distribution capabilities while minimizing interference. Poorly designed PCBs can significantly impact signal transmission, manufacturability, power delivery, and long-term reliability.
Multilayer PCBs offer extensive opportunities for creativity and can fully realize the potential of electronic circuits. Therefore, it is wise to entrust the design process to reputable companies that specialize in producing high-quality electronic products.
By engaging reliable design companies, design engineers can be assured of technically sound PCB designs that meet their specific requirements, including optimized stack-up configurations that meet the needs of high-speed circuits. These design firms have the expertise and best practices necessary to produce PCBs that provide excellent manufacturability, functionality, and reliability over the product’s lifetime. Ultimately, this approach can lead to high-quality electronic products with excellent performance and longevity.
Common PCB Layer Stack-Up Configurations
There are several common PCB layer stack-up configurations, including:
● 2-Layer PCB Stack-Up: Consists of two layers of copper, separated by a substrate material. This is the simplest type of PCB and is often used for low-speed or low-complexity circuits.
● 4-Layer PCB Stack-Up: Consists of two internal signal layers and two power/ground planes, separated by substrate layers. This is a common layer stack-up for complex, high-speed PCBs.
● 6-Layer PCB Stack-Up: Consists of two internal signal layers, two power planes, and two ground planes, separated by substrate layers. This stack-up is commonly used for high-speed or mixed-signal PCBs.
● 8-Layer PCB Stack-Up: Consists of four internal signal layers and two power/ground planes, separated by substrate layers. This stack-up is commonly used for very complex, high-speed PCBs.
● 10-Layer PCB Stack-Up: Consists of six internal signal layers and two power/ground planes, separated by substrate layers. This stack-up is commonly used for extremely complex, high-speed PCBs with multiple high-speed interfaces.
The exact layer stack-up used for a PCB depends on the specific requirements of the circuit and the system it is a part of, as well as any manufacturing or cost considerations.
Summary

How Many Types for Turnkey PCB Assembly ?
Turnkey PCB assembly services can be categorized as partial or full depending on the extent to which the third-party provider is involved in the assembly process.
Basics of Full Turnkey PCB Assembly
Full Turnkey PCB Assembly is a comprehensive service that involves the assembly of a complete PCB, from component procurement to final testing and inspection. This means that the PCB supplier manages the entire process, from selecting and purchasing electronic components and PCB fabrication to assembly, testing, and delivery. The supplier is responsible for ensuring that all components and materials are of the highest quality, and that the final PCBs meet all specifications and requirements.
The full turnkey method eliminates the need for the customer to manage multiple vendors or contractors, as the PCB supplier handles everything from start to finish. This approach is ideal for customers who do not have the time, resources, or expertise to manage the PCB Assembly process themselves. Additionally, full turnkey PCB Assembly offers faster turnaround times, improved quality control, and lower overall costs compared to other methods.
Some of the benefits of full turnkey PCB Assembly include:
● Reduced lead times and fast delivery. ● Consistent quality control throughout the entire process. ● Lower overall costs due to bulk purchasing power. ● Increased production efficiency. ● Single point of contact for all aspects of PCB Assembly.

The manufacturing process of PCBs is influenced by multiple factors, with the thickness being a key variable. The electrical conductivity and resistance of a PCB are significantly impacted by its thickness. Therefore, it is crucial for PCB manufacturers to carefully choose the appropriate thickness to ensure an optimal fit for a given application. Precision and accuracy in selecting the ideal thickness are essential for ensuring proper functionality and performance of the PCB.
Printed Circuit Boards (PCBs) are the backbone of modern electronic devices, serving as a platform for connecting and controlling various components on a circuit. Therefore, PCB thickness is a crucial factor in its design that can have a significant impact on performance, durability, and reliability. Different types of PCBs require distinctive thickness, and selecting the right thickness for your PCB is central to achieving optimal performance and longevity. In this article, we will provide an overview of standard PCB thickness, including the factors that impact it and how to choose the right thickness for your needs.
What Is PCB Thickness ?
PCB thickness refers to the overall depth or height of the printed circuit board. It is typically measured from the surface of the copper traces or planes on one side of the board to the surface on the opposite side. The thickness of a PCB affects its mechanical strength, electrical performance, and heat dissipation characteristics. Different types of PCB applications may have different requirements for thickness, and choosing the right thickness is important for ensuring optimum performance and reliability of the circuit board.
Many PCB contract manufacturers advertise 1.57mm or 0.062in as the standard PCB thickness. This reference is accurate to some extent, given that bakelite sheets were historically produced in this size during the early days of board fabrication. Consequently, this size has become the standard PCB thickness throughout history. Despite this standard, contemporary boards are available in varying sizes, both larger and smaller than the traditional 0.062in size. However, it is still widely accepted that 0.062in is the most common thickness for most designs.
In reality, there is now a range of common or standard PCB thicknesses available, including 0.031in (0.78mm), 0.062in (1.57mm), and 0.093in (2.36mm). Depending on the specific requirements of the job, custom-ordered boards with differing thicknesses can also be ordered from PCB manufacturers. PCB manufacturers must consider several factors during the design and manufacturing phase when determining the appropriate PCB thickness. The factors may include but not limited to:
Design Factors Influencing PCB Thickness
●Signal Types: The various signal types carried by PCBs have a direct impact on the selection of materials used for board production, and subsequently, the thickness of the board itself. For instance, PCBs that carry high power signals require thicker copper layers and wider traces, necessitating a significantly thicker board compared to low power signal boards.
Conversely, high-density PCBs that carry more complex signals tend to be thinner than other board types. This is due to the use of thin, high-performance materials and laser microvias, which allow for the creation of fine traces and higher density interconnections. PCB electronic engineers must be knowledgeable of these signal-specific board thickness requirements to select optimal materials and ensure efficient PCB design and development.
●Types of Vias: PCB vias play a critical role in the design process by routing traces through the-board, allowing for more compact and optimized designs. There are several types of vias available for such purposes, including:
The choice of via type and its density can impact the PCB thickness required to accommodate them. For instance, thinner boards can utilize micro vias due to their smaller size and ability to support high-density connections. In contrast, larger or more widely-spaced vias will likely require a thicker board to maintain acceptable structural integrity. PCB electronic engineers must consider these factors to determine the optimal board thickness, ensuring successful design implementation and functionality.
● PCB Board Materials: For PCB manufacturers, the materials utilized in the fabrication of a PCB play a crucial role in determining the operational performance and lifespan of the board, as well as its thickness. The typical construction of a PCB consists of substrate, laminate, solder mask, and silkscreen; however, substrate and laminate are of particular importance in relation to board thickness. Both substrate and laminate are responsible for providing the foundation and structure of the PCB and, therefore, impact its overall thickness significantly.
The substrate material used may differ depending on the dielectric constant required, with options including paper and epoxy resin, glass weave, or ceramic. Laminates are constructed using a thermoset resin layered with paper or cloth. Both substrate and laminate offer various configurations, significantly impacting the circuit board’s thermal, mechanical, and electrical properties, as well as its overall thickness. PCB manufacturers must consider the desired performance requirements when selecting the optimal material configuration, balancing design goals with practical considerations to ensure the highest quality and most efficient results.
●PCB Copper Thickness: In PCB manufacturing, the thickness of copper utilized plays a vital role in the determination of the board’s overall thickness. The copper layer thickness is typically determined based on the amount of current that must flow through the PCB. The standard copper thickness for PCBs is between 1.4 and 2.8 mils (1 to 2 oz). However, specific board requirements may necessitate adjustments to these standards.
As thicker copper layers require additional materials and imposing processing challenges, they translate into a thicker board, and ultimately, a higher production cost. With the copper thickness being a major determinant of overall PCB thickness, manufacturers must make informed decisions about copper layer thickness to meet performance requirements while maintaining practical and economic constraints.
● Number of PCB Layers: As a PCB design engineer, it is crucial to consider the number of layers required, as this will significantly impact the board’s thickness. Two to six-layer PCBs typically fall within the standard PCB thickness range, but eight-layer and higher PCBs may require a non-standard thickness. While it may be possible to achieve standard thickness by using thinner PCB layers, this becomes increasingly impractical as the number of layers increases.
In the event of a design requiring more layers, it is advisable to accommodate a thicker PCB. On the other hand, if a design must adhere to specific thickness parameters but doesn’t require multiple layers, reducing the number of layers is recommended. By considering such crucial factors, PCB designers can develop effective designs that meet requirements for performance, practicality, and cost-effectiveness.
●Operating Environment: As a electronic manufacturer, it is crucial to acknowledge that a PCB’s thickness and materials greatly influence its conductivity and resistance, making it critical to select an appropriate thickness for specific environments.
For instance, a thin or flexible board may not be the best option for challenging operational conditions. Similarly, designing thicker copper traces may not prove suitable for high-current or thermally variable environments due to limited thermal stability. It is imperative to carefully evaluate the material and performance requirements of the connectors and components on the PCBs in relation to the board’s thickness. This evaluation helps designers reasonably determine whether a standard or custom PCB thickness is preferable, depending on the operational requirements, practicality, and cost-effectiveness.
However, the design process does not end here; manufacturers must also play an active role in the process to discuss their capabilities and limitations and how these may impact the final PCB design. Effective collaboration between designers and manufacturers facilitates the development of high-quality PCBs that meet the desired performance requirements while remaining viable and cost-effective.
The Influence of PCB Thickness in the Manufacturing
●Layer Count: As a PCB designer, it is essential to recognize that more layers on a board can make it increasingly difficult to achieve a standardized thickness during manufacturing. While some specialty manufacturers may be capable of creating stacked PCBs with thinner layers to meet specific thickness requirements, this capability may not be universal and often comes with an associated cost increase.
It is imperative to consult with the manufacturer before finalizing the board design to gauge their capabilities and determine what they can achieve in terms of layering requirements. Conducting these discussions before finalizing the design helps identify and address any potential issues in advance, ensuring that the design meets all necessary specifications. Moreover, effective collaboration between designers and manufacturers helps deliver high-quality PCBs that achieve the desired performance goals while remaining practical and feasible in terms of manufacturing and costs.
● Copper Thickness: As a PCB manufacturer, it is crucial to acknowledge that etching is one of the most crucial steps in PCB fabrication for creating copper traces. The thickness of the internal copper layer directly impacts the etching and plating manufacturing processes. Consequently, thicker copper layers will have a notable impact on the overall PCB manufacturability, which can potentially affect the board’s design and production cost. It is therefore essential to consider the copper layer thickness during the initial design stage to ensure the chosen thickness meets the manufacturing process’ requirements and remains within the available budget.
By working closely with designers to evaluate copper thickness requirements, manufacturers can deliver high-quality PCBs that meet the necessary performance goals while remaining feasible and cost-effective.
● Drill Hole Equipment: As a PCB manufacturer, it is crucial to recognize that while drill hole size and spacing are vital considerations in achieving performance goals, drilling holes in PCBs introduces a new layer of complexity in the manufacturing process. Manufacturers face limits in drilling holes through the thickness of the board, which are determined by milling machines and lasers’ diameter and depth. This limit is represented by an aspect ratio, which is the ratio of the hole’s depth to the diameter of the drill hole. For standard drilling, all manufacturers should be able to achieve a 7:1 aspect ratio.
However, some manufacturers may achieve a higher aspect ratio, but this will raise the board’s cost and needs to be discussed with the manufacturer before finalizing the board design. Thicker boards can limit manufacturers’ ability to drill smaller diameter holes. By considering the aspect ratio limitations during the design stage, designers can develop an effective design that accommodates the necessary performance requirements while remaining practical and cost-efficient. Effective collaboration between designers and manufacturers further ensures the production of high-quality PCBs that match the desired performance profile.
●Depanelization Method: As a PCB manufacturer, it is critical to acknowledge that depanelization is another crucial manufacturing consideration. Typically, PCBs are fabricated on large panels containing several boards that are later separated to create individual boards. The thickness of the board influences the depanelization method utilized. For instance, thicker boards necessitate careful scoring, whereas thinner boards may be routed to create breakaway tabs. To optimize depanelization, it is vital to work closely with the manufacturer and discuss the various depanelization techniques as well as any unique depanelization requirements.
It is essential to engage the manufacturer in these discussions before completing the final PCB design since these manufacturing factors are dependent on the manufacturer’s capabilities, methods, and associated costs. Failure to discuss these elements earlier in the design process can result in modifications or complete redesigns of your layout, leading to additional costs. Therefore, PCB manufacturers must collaborate effectively with designers and provide critical input on manufacturing requirements to ensure a smooth production process that produces high-quality and cost-efficient PCBs.
Standard PCB Thickness Types
Standard PCB thickness can vary depending on the specific type of board and its intended application. Here are some typical thickness values for various types of PCBs:
●Single-layer PCB thickness: Between 0.4 mm and 1.6 mm.
●Double-layer PCB thickness: Between 0.8 mm and 2.4 mm.
These values are considered standard in the industry and are used by PCB manufacturers as a guide in the design and production of circuit boards. However, it’s essential to consider the specific requirements of each application to ensure the selected thickness is appropriate for the performance and reliability needed. Additionally, custom thicknesses may be required in unique cases, such as those with specific design constraints or unusual requirements for thermal management or structural support.
Considerations When Choosing PCB Thickness
Choosing the appropriate PCB thickness depends on various factors, such as the complexity of the circuit design, board size, component density, thermal management requirements, and mechanical constraints. Here are some factors to consider when selecting the right PCB thickness:
●Mechanical strength: If the PCB will be subjected to stress or external loads, it’s important to have enough thickness to ensure mechanical strength and avoid bending or breaking.
●Component density: High-density PCBs or those with large components may require thicker thickness to accommodate the component height and prevent interference between them.
●Thermal management: For applications with high power dissipation or significant heat generation, a thicker PCB can provide better thermal performance by allowing for more effective heat dissipation.
●Electrical properties: The thickness of the PCB can influence impedance, signal integrity, and electrical properties. It is critical to match the board thickness to the impedance. This is due to the fact that the thickness of the board is actually the thickness of the dielectric, and the dielectric aids in impedance control. Therefore, the selected thickness must meet the specified requirements of the circuit design.
●Cost and manufacturing: Thicker PCBs may be more expensive and require additional manufacturing steps that can affect the cost and time to manufacture the board.
●Equipment Capabilities: When manufacturing PCBs, it is critical to evaluate whether the manufacturer has the necessary equipment to achieve the desired board thickness. Moreover, if an application requires intricate features that can only be realized through advanced design techniques, it is crucial to identify manufacturers who can meet such requirements as early as possible.
However, such techniques generally come with added costs that need to be taken into account. By prioritizing a deep understanding of client requirements during the design phase, manufacturers can effectively match client needs with production capabilities, while also ensuring a cost-effective outcome. Effective collaboration between manufacturers and clients is essential in developing and delivering high-quality PCBs that accurately align with all specifications, such as performance, manufacturing, and budget.
Turnaround Time: In PCB manufacturing, standard thicknesses present minimal difficulties, and the production process requires very few adjustments. However, for custom thicknesses, adjustments are necessary, which can significantly increase production time. Adapting existing equipment settings and processes to fit the custom design requirements can be time-consuming and affect the manufacturing schedule, potentially delaying turnaround time.
If the design includes complex features, this will further increase the manufacturing time. Therefore, when considering a custom PCB thickness, it is crucial to engage with the manufacturer to obtain an accurate estimate of the time required for its production. By liaising with the manufacturer, clients can adjust their delivery timelines accordingly, preventing any uncertainty or delays. Collaborative communication between manufacturers and clients is essential in developing high-quality, custom PCBs that precisely match performance requirements while remaining feasible in terms of manufacturing time and budget constraints.
●Additional Cost: As experienced PCB engineers, it is crucial to carefully evaluate the cost-effectiveness of producing a custom circuit board for your company. Standard-thickness boards offer significant advantages, including reduced manufacturing costs and avoidance of potential delays associated with custom-thickness boards. Therefore, it is imperative to make a thorough analysis of the cost-benefit trade-offs before deciding on a custom-thickness board. While it is true that using special materials to accommodate a standard thickness may be more expensive, it could potentially outweigh the costs associated with modifying a custom-thickness board. It is essential to take all relevant factors into account and make a well-informed decision that aligns with your company’s goals and requirements.
So, selecting the right PCB thickness requires consideration of various factors that impact the performance, reliability, and manufacturing of the board. The selected thickness should meet the specific needs of the application while balancing design requirements, manufacturing costs, and other practical considerations.
Conclusion
PCB thickness standards vary according to the type of board and intended application, and custom thicknesses may be required in some cases. Ultimately, selecting the appropriate PCB thickness requires balancing the requirements of the intended application with considerations of manufacturing cost, design complexity, and other practical considerations.
