Rigid-flex PCB BoardsDate: 2022-04-15

A Rigid-Flex PCB is a hybrid circuit board combining elements of both flexible circuit boards and rigid circuit boards, with an end result of a board that is able to be folded or continuously flexed and is normally formed into a flexed shape or curve. The flexible layers of a Rigid-Flex PCB are buried within the board and penetrate through the rigid sections of the PCB.


A rigid-flex printed circuit board can help you with issues in reducing space, as well as making sure your products can stand up to tough conditions and ensuring they are cost-efficient. A rigid-flexible format allows you to use fewer parts and interconnections and take on more aggressive design challenges, as the rigid-flex PCB is a flexible solution to numerous design issues. Applications for industries range from hearing aids to night vision goggles and more.


You can always rely on our one-stop services for complete end-to-end delivery on your next PCB project. Alternatively, we’re equally happy to be brought in for one part (or several stages) of the design, prototyping, manufacture and assembly process.

Rigid-flex PCB Boards Design

The designs of Rigid-flex PCBs are a little more complex as these boards are designed in 3D, which allows the board to be folded or twisted to create the desired shape for the product. Designing a board in 3D means they can offer greater spatial efficiency and can subsequently be used in special instances where space and weight reduction may be necessary, such as in medical devices.

Rigid-flex PCBs are usually thinner than other boards, meaning it’s a great option for any thin or light packaging needs your products may have. With thin copper layers and adhesive-less laminates, it’s a great small, thin and light solution for your circuit design needs.

With our rigid-flex PCBs, we can offer cost-effective, high-quality, flexible products that can withstand bending stresses.

Benefits of Rigid-flex PCBs

There are several benefits to a Rigid-flex PCB which could make it a perfect choice for your product, including:

• Portability on account of the reduced package space and flexibility afforded by the boards.
• Ruggedness on account of use of a flexible substrate. Such PCBs are known to withstand high temperature, electronic, magnetic transmission, high vibration environments and more.
• Ease of testing, hence they find wide application, particularly prototypes.
• Reliability on account of reduced number of solder joints.
• Fit for use in high-density applications.
• Secure connection with the assurance of polarity and contact stability.
• Simplified installation and maintenance of uniform electrical characteristics.
• Reduced cost.

If your product requires a board that needs to be folded when assembled or you’re after something highly durable and long-lasting then a Rigid-flex PCB might be the right fit for you.


Uses of Rigid-flex PCBs

Other than being used for electronic devices, rigid-flex circuit boards have a wide range of commercial and industrial applications. They are also used for high grade aircraft mounted weapon guidance systems; rigid-flex printed circuit boards are widely adopted for military and aerospace electronic manufacturing.

Other rigid-flex PCB applications include:

• ABS sensors
• CT scans
• Digital cameras
• Smart jackets
• Cell phones
• Barcode scanners
• Pacemakers


Our Capabilities

At unitepcb, we work hard to get your rigid-flex PCBs to you quickly, provide the quantities you need and meet your required specifications. We also pride ourselves on providing advanced options for your boards. For instance, we offer penalization optimum, which arranges your rigid-flex boards into large multi-unit panels you can easily break apart for use, and shielding, which minimizes electromagnetic interference. We can also use pressure-sensitive adhesives (PSAs) to secure sections of a PCB in place without using soldering.
