Rigid Vs. Flex Printed Circuit Boards

Rigid Vs. Flex Printed Circuit Boards


In the high-pressure world of Aerospace & Defense electronics, it is important to understand the difference between rigid PCB’s and flexible PCB’s. The most obvious difference lies in their name – rigid feature a more stiff and inflexible design, whereas flexible are more adjustable and bendable. 

Rigid and flexible PCB’s are used in many different products, though determining which type of circuit board is most appropriate for an individual application’s demands can be tricky. 

Rigid Printed Circuit Boards

Rigid circuit boards are typically inexpensive and used in applications with greater space availability where flexibility is not required. For example: Televisions and desktop devices.

Flexible PCB

Flexible circuit boards are known for their ability to bend and shape into more compact applications, often required in mission-critical A&D devices. Example: wearable technology.

As devices are becoming smaller and more advanced, printed circuit board design is seeing an increase in the use of flexible PCB’s, especially in critical industries like medical, aerospace, military and space.

Unlike rigid PCB’s, Flexible circuit boards are known to be small and lightweight yet highly durable, making them ideal for the extreme and hazardous conditions often inherent to high-stakes applications.
