Rigid-Flex PCB
Rigid-flex PCBs are flexible circuit boards and rigid circuit boards, which are combined according to relevant process requirements after lamination and other processes to form a circuit board with FPC characteristics and PCB characteristics.
It can be used in some products with special requirements. It has both a certain flexible area and a certain rigid area. It is of great help to save the internal space of the product, reduce the volume of the finished product, and improve the performance of the product.
