4 Layer(2 Layer FPC +1 Layer Rigid PCB +1 Layer FPC) Board for Radar

♦ What is Rigid-Flex PCB?

Rigid-Flex PCB is a composite structure circuit board that combines a rigid printed circuit board (PCB) and a flexible circuit board (FPC). It is mainly composed of two parts: rigid and flexible. The rigid layer is made of traditional PCB materials (such as FR-4), providing stable electrical performance and mechanical strength; the flexible layer is made of flexible circuit materials such as polyimide or polyester, which has high bending and folding resistance; the two are connected by special adhesives or welding processes.

♦ Features of Rigid-Flex PCB

• • Rigid-flexible combination: the rigid part supports the core components, and the flexible part is bent.

  • ​​Space saving: replace the cable and reduce the size of the device (suitable for thin and light design).

  • ​​High bending resistance: the flexible part can be bent repeatedly (millions of times of life).

  • ​​Signal stability: the rigid part ensures high-speed signal transmission and reduces interference.

  • ​​Strong reliability: anti-vibration, high temperature resistance, and adaptable to complex environments.

  • Simplified assembly: integrated design, reducing welding points and reducing costs.

♦ Applications of Rigid-Flex PCB

• • Consumer electronics: smart phones, tablets, smart watches, digital cameras, portable cameras, etc., used to save internal space, achieve multi-functional integration and meet the needs of foldable design.
  • Medical equipment: pacemakers, medical imaging equipment, portable medical instruments, implantable devices, etc., adapt to complex human environments and achieve flexible connections.
  • Aerospace: aircraft instrument panels, navigation systems, communication equipment, radar systems, etc., meet the requirements of lightweight, high reliability and resistance to extreme environments.
