Rigid-flex PCBA is a hybrid circuit board that integrates both hardboard and flexible circuits. It can be assembled like hard boards, and then fold-installed into the device. The circuits are typically multi-layered and are comprised of flexible circuit substrates joined with rigid boards. The flexible layers are buried internally and completely penetrate the rigid sections of the PCB, could be any layer of the rigid PCB.
While Rigid-flex PCB is more expensive, rigid-flex PCBA boards are extremely versatile and can be tailored to applications across a wide range of industries. Could be a good choice for applications such as:
- Applications with high-shock and high-vibration: Rigid flex PCBs are highly shock resistant and can survive in high-stress environments that would otherwise cause equipment failure.
- Applications with high-density, without much space for connectors, and also help to reduce the assembly operations/increase the reliability.
