They can not only assist you with finding the right PCB for your product, but they can also provide you with a quote if needed.

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 are a type of circuit board that is rigid concerning their structure and consequently are unable to be bent or flexed. They are made up of different layers, including the substrate layer, a copper layer, a solder mask layer, and a silkscreen layer that are joined by the use of heat and adhesive.

Some circuit boards can be single-sided, multilayered or double-sided. Depending on the application, rigid PCBs can be made in any combination of these formats. But once they’ve been made, they are not able to be altered or altered.

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:


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.


Rather instead of having just one conductive layer on the board, double-sided PCBs have copper-based conductive layers on both sides. With twice the space for components, double-sided PCBs offer more design options and greater circuit complexity, which allows them to be used in a wide range of 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 are more expensive than rigid PCBs. However, we’re referring to the specific costs of the PCB that is flexible. While it is possible for the overall cost of rigid PCBs to be more costly than flexible, flexible PCBs may have a high cost per unit.

● 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 electronic gadgets (laptops as well as desktop computer audio keyboards, solid-state drives (SSDs) and flat-screen televisions and monitors, toys for children, and other electronic gadgets) utilize rigid PCBs in place of flexible PCBs. Flexible circuits are possible in small or high-performance gadgets such as GPS devices and tablets, smartphones, cameras, wearables, and smartphones.

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.
