Definition of Rigid Circuit Board

As the most traditional form of PCB, rigid circuit boards remain highly popular today and are used in many products consumers use every day.

Rigid PCBs represent a category of circuit boards distinguished by their inflexible structure, which prohibits bending or flexing. Comprising various layers such as the substrate, copper, solder mask, and silkscreen layers, these boards are fused together using heat and adhesive bonding techniques.

Some Circuit boards possess the capability to be fashioned in single-sided, double-sided, or multilayered layouts, thereby providing adaptability to cater to a myriad of application necessities. Rigid PCBs permit customization in any amalgamation of these formations, contingent upon the particular stipulations of the target application. Nevertheless, post-manufacturing, rigid PCBs are resistant to any modifications or adjustments.

Rigid PCB Type

One of the benefits of rigid PCBs lies in their capacity to be utilized for different project specifications and configurations. At JarnisTech, we provide rigid PCBs of a variety of designs, such as:

One-sided: Single-sided Circuit boards are the original PCB. They feature one coating of electrically conductive materials and all components are placed on the same face of the board. Because of their simplicity Single-sided PCBs are quick and easy to produce which reduces the possibility of errors. This configuration is cost-effective and works best in designs with low density.

Double-sided: Rather instead of having just one conductive layer on the board, double-sided PCBs have copper-based conductive layers on both sides. This design provides room, for components enabling more diverse design possibilities and increased circuit intricacy. As a result sided PCBs are versatile and can be utilized in various applications.

Multilayer PCB: A PCB with this type of construction uses three or more layers of conductive material stacked in the middle, with several other layers surrounding the core. By using numerous layers and an advanced curing process, multilayer PCB boards reduce interconnection wiring, save space, and result in dense and tough boards.

Carriers Board, Also Known as Mechanical Spacer: If you require a sturdy backer to support the assembly process for extremely thin PCBs. Some businesses may choose to use an uncoated carrier board with no conductor layer. Any circuit board that is used for mechanical operations does have any copper layers or require any electrical connection. At JarnisTech, we are able to create a bare rigid PCB according to your design as per your specifications, to accommodate all the components and equipment that you plan to use.

Benefits of Rigid PCBs

PCBs with rigid construction has the following advantages

Small Size: One of the major advantages associated with rigid PCBs is their small size. It’s known to take up less space, and with miniaturization becoming more common the significance of PCBs is not overstated.

Low Electronic Noise: Rigid PCBs are known for their ability to reduce electronic noise. This is due to the way that electronic components are put together in a way that the current between them is minimized so that the PCB will not pick up electromagnetic waves and decreases crosstalk.

Immunity to Movement: Utilizing solder flux to secure parts to the PCB, they will not move, regardless of whether the board is subjected to harsh conditions.

Ease of Repair: These PCBs are suited to repairs that are simple. Additionally, the process of assembly is relatively simple.

Uses of the Rigid PCB

Rigid printed circuit boards provide increased circuit density and also reduce the weight and size of the boards. This is the reason why numerous electronic companies around the world utilize the boards in various electronic gadgets and devices:

● Satellite.
● Equipment.
● Industrial Equipment.
● Atomic and Nuclear Systems.
Telecommunications Equipment.
● Storage of data and File server.
● Diagnostic Equipment for Health Care.
Military and Defense Equipment.
● Laptops and Computers and Laptops.
● Signal transmission, repeaters for mobile phones, GPS.

Comparative Analysis Between Flex and Rigid PCBs

Most electronic devices utilize rigid PCBs. Howerver, Technology has advanced, and many products have discarded rigid PCBs because they can’t be folded or twisted. As a result, this has spawned the idea of flexible PCBs, Flexible PCB was born and quickly became a standard for professionals in the market.

● Manufacturing procedure for both flexible and rigid PCBs is similar, with a few exceptions in regards to their flexibility, softness, and cost.

● Some additional measures are needed to process flex PCB in terms of handling materials. Proper specifications are also required to prevent cracked solder joints from occurring when the board bends.

● Flexible PCBs typically bear a costlier price tag in comparison to their rigid counterparts, especially when narrowing down to the immediate outlays tied to PCBs. Despite the occasions where the cumulative cost of rigid PCBs overshadows that of their flexible equivalents, the per-item cost of flexible PCBs is generally elevated, primarily due to their sophisticated design and singular attributes.

● Many low-cost electronics utilize rigid PCBs, such as desktop devices, audio keyboards Solid state drives, toys, and other electronic devices. But, flex circuits are found in ultra-high performance devices since they don’t involve connectors and are also thinner than rigid boards. They can be utilized in cameras, smartphones, tablets and GPS control systems.

● Both flexible and rigid boards can be combined to create a single product with durability and flexibility.

● Flexible PCBs can be manufactured using the same design principles used for rigid circuit boards, but they are not exactly the same.

● Flexible PCBs offer flexible and bent solutions. They are smaller and more space-efficient and mostly Single Sided PCB.

When to Use Rigid and How to Use Flexible?

The rigid PCBs are generally less expensive than flexible circuits. I typically use “typically” since when you think about all costs of owning, there are certain applications that use flexible PCBs that could be more affordable than rigid PCBs.

To have a complete and precise understanding of the overall cost, you need to first understand the fact that flex circuits could remove the requirement for components like wire harnesses, connectors, and various circuit boards. When these components are removed from a design, the material cost, as well as assembly and labor costs as well as scrap costs are all cut down.

A lot of gadgets like laptops, desktop computers, flat screen TVs and even childrens toys mostly use rigid PCBs instead of flexible ones. On the hand flexible circuits are commonly used in smaller or high tech devices, like GPS systems, tablets, smartphones, cameras, wearables and handheld electronics.

More sophisticated is not the only reason for using flexible circuits. Even low-tech products like LED lights could make use of the flex circuit in certain instances because it makes the installation easy.

Materials Considerations

The materials in your rigid PCB are based upon the specifications of your project. You can create your rigid PCB using many material options.

At JarnisTech, We offer PCBs with special metallic cores like aluminum which have excellent thermal conductivity while remaining economical. The metal core we employ is based on your specifications of your and requirements for conductivity.

Your adhesive will differ depending on the specifications of your project and the conductor’s thickness. The options include:

● Epoxy.
● Acrylic.

We will offer an insulator that can provide robust signal transmission and safety. The materials that could be used include:

Coverlays, covercoats, and solder mask layers.
● Standard materials from FR-4.
● Lead-free compatible materials for FR-4.

The most popular kind of PCB that is rigid, FR-4 boards have a fire-resistant fiberglass layer to increase rigidity and resistance. These boards are extremely light and resistant to moisture and temperature, which makes them a great option for a variety of applications.

For PCBs that operate at high temperatures, high-Tg circuit boards have a glass transition temperature (Tg) above 150 degrees Celsius. If you’re working with high-power circuits, the temperatures generated by the circuit could overpower a conventional PCB’s techniques for managing heat. High-Tg boards are the best option in these situations.
