Rigid-Flex Printed Circuit Board (Rigid-Flex PCB)
Rigid-flex board, fully known as rigid-flex printed circuit board (Rigid-Flex PCB), is a type of circuit board that organically combines rigid boards (Rigid PCB) and flexible boards (Flexible PCB, FPC) through a lamination process. It possesses both the mechanical strength of rigid boards and the bendability of flexible boards, enabling three-dimensional installation and meeting the demands of modern electronic products for high-density assembly, thinness, miniaturization, and high reliability.
Structural Features of Rigid-Flex Boards
- Rigid area: Uses traditional rigid PCB materials (such as FR-4) for supporting, mounting, and fixing components.
- Flex area: Uses flexible materials such as PI or PET, which can be bent and folded, for space layout and dynamic connections.
- Integrated structure: The rigid and flex areas are firmly combined through a special lamination process to form an integrated structure.
Main Advantages of Rigid-Flex Circuit
- Supports three-dimensional space design, making it easy to achieve complex structures and compact layouts.
- Improves product reliability by reducing the number of connectors and solder joints, thus lowering failure rates.
- Saves space and weight, suitable for portable and highly integrated devices.
- Facilitates automated assembly and improves production efficiency.
Application Fields of Rigid-Flexible PCB
- Consumer electronics such as smartphones, tablets, and wearable devices.
- Medical electronics, aerospace, and military equipment.
- Automotive electronics, industrial control, and high-end instrumentation.
