Flex PCBs, also known as flexible printed circuits or flexible electronics, provide greater options for designers and engineers when assembling electronic circuits.
They are constructed from flexible, high-performance plastic material, usually polyimide, which permits the board to be bent (or flexed). This property of flexibility enables their use in a wide variety of applications. They can be built with stiffeners, to create areas that are not able to be bent. They are also used along with rigid pcb to create a rigid-flex assembly to give rigid PCB bendable qualities.
Below are some of the most common types of flex PCB construction:
- Single-sided flex pcb
- Back-bared flex circuits
- Double-sided flex pcbs
- Sculptured flex circuit board
- Multi-layer flex circuits
- Rigid flex pcb
