As the name implies, a rigid flex PCB is a combination of both rigid and flexible substrates. One or more flexible circuits are used to connect subcircuits on rigid PCBs. Rigid flex PCBs are usually produced with flexible polyimide material on copper cladding substrate and connects to the rigid FR4 board.
The flexible part of the rigid flex PCB usually features a multilayer built with padded through holes securing the interconnectivity between layers. Rigid flex PCB has grown from merely using the flexible substrate as a replacement for wire harnesses, to having actual subcircuits built on the flexible area itself.
Advantages Of Rigid-Flex PCB
Designing a rigid flex PCB is considerably more challenging than conventional rigid PCB. However, there are good reasons why rigid flex is used in some designs, particularly one that involves fitting the board in tight spaces.
