Rigid-Flex PCB

What is a Rigid-flex PCB?

A rigid-flex PCB combines rigid and flexible PCB technologies into a single hybrid design. This type of printed circuit board features both rigid sections for mounting components and flexible sections for bending or folding, offering durability and versatility.

This hybrid design:

Reduces connectors and cables

Simplifies assembly and improves reliability

Supports miniaturization and complex 3D geometries·

Stack-up and Materials

Rigid-flex PCB combines the advantages of rigid PCB and flex PCB. It is made of flexible material layered on top of rigid material, creating a board that is rigid in some parts and flexible in others. From the picture beside, you can clearly understand the stacking structure of Rigid-flex circuit board.
