Rigid flex PCB design guidelines
What is Rigid Flex Boards?
Rigid flex boards are a combination of both flexible and rigid circuit boards. Also, typical methods to manufacture them are similar to those utilized on circuits of rigid boards.
However, some of these layers feature a flexing or flexible circuitry that runs from this rigid board into the board. Then the manufacturer makes use of a plated hole in the boards linking the layer of the rigid circuit to the region of the flexible circuit.
This configuration leads to a rigid flex pcb, which you can install easily as a rigid board. Also, for products having limited room, it can be folded easily. Furthermore, the devices have a flex-ability feature that can be referred to in some cases as dynamic flexion.

Material Layout Considerations for Rigid Flex PCB Design
Before you begin a design, it is advisable to reach out to your manufacturer. Depending on if the printed circuit board is for stable bend or dynamic bend, there may be differences in the choice of bend radius, layers, coverlays, and copper type.
Rigid flex PCBs of dynamic bend are usually installed in environments where you can subject it to bending constantly. Therefore, a great recommendation will be to use a maximum of 2 layers. Also, make sure that the radius of the bending is at about 100 times the thickness of the material.
For example, having about 10 – 20 layers of rigid flex PCB that should serve stable-bond installations is possible. It will not be made to undergo continuous bending force. This means having a bending radius of 10 times the material thickness is possible as well.
Furthermore, the flexible material’s flex lay up has a huge effect on the costs to manufacture them as well as the PCB’s final performance. Therefore, it is important to choose the best material possible. Moreover, some major considerations in both the choice of material and copper weights include controls on load-carrying requirements and impedance resistances.
Also, there is a need to collaborate with the assembler to discuss the design of your PCB. This is to make sure that all the components work in line with the requirements of signal integrity.
