Flex rigid PCB:Material Considerations for Rigid-Flex PCB Design Talk to your manufacturer to ensure you select the right material for your rigid-flex design TYou’ll want to consult your PCB manufacturer before starting a design.

Flex rigid PCB:Depending on whether the PCB is meant for dynamic bend or stable bend, the choice of copper type, the number of layers, bend radius, and coverlays may differ. TA dynamic bend rigid-flex PCB is installed in an environment where it will constantly be subjected to bending.


Therefore, it is recommended to use no more than 2 layers and ensure that the bending radius is at least 100 times the material thickness.

TMeanwhile, it’s possible to have up to 10 to 20 layers for a rigid-flex PCB that’s meant for stable-bend installations. It is not subjected to repeated bending force and that means a smaller bending radius of about 10 times its material thickness is also possible.
