High Reliability Rigid-Flex PCB Communications Equipment Bending Resistance PCB Manufacture

♦ 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

• • ​​Efficient wiring: High-density multi-layer design to meet the needs of complex circuits.

  • ​Widely used: Covering aerospace, medical, automotive, consumer electronics and other fields.

  • ​​Reduce failures: Reduce welding points and cable connection problems, improve product stability.

  • ​​Strong impact resistance: Resistant to high stress, suitable for harsh scenarios such as vibration and collision.

♦ Applications of Rigid-Flex PCB

• • ​​Consumer electronics​​: smartphones (internal connections of folding screens), wearable devices (circuits inside smartwatch straps), tablet computers (circuit boards at hinges);
  • Industrial and medical​​: industrial sensors (detection modules that need to be bent and installed), medical implants (internal circuits of pacemakers), avionics equipment (control modules that need to resist vibration);
  • Automobile and transportation​​: battery management systems for new energy vehicles (BMS, adapted to complex battery pack layouts), on-board displays (foldable or curved screen connections), autonomous driving sensors (dynamic bending requirements);
  • ​Military and aerospace​​: satellite communication equipment (needs to be lightweight and radiation-resistant), aircraft control circuit boards (adaptable to high-vibration environments).
