Rigid-flexible PCB solve many difficulties that rigid or flexible boards cannot, and many industries widely use them. Telecom, military, medical, auto, AI etc need such boards in high frequency.
Rigid-flexible PCB Brief description:
The birth and development of FPCB and PCB gave birth to a new product of soft and hard board. Therefore, the rigid-flexible pcb is the combination of flexible circuit board and the rigid circuit board. After pressing and other processes, they are combined according to the relevant process requirements to form a circuit board with FPC characteristics and PCB characteristics.
Production Process:
Because the rigid-flexible pcb is a combination of FPC and PCB, the production of rigid-flex board should have both FPC production equipment and PCB production equipment. First, the engineer draws the circuit and shape of the flexible board according to the requirements, and then sends it to the factory that can produce the flexible and rigid board. The CAM engineer processes and plans the relevant documents. And then arranges the FPC production line production site FPC and PCB production lines are required to produce PCB. Workers laminate the FPC and Rigid PCB seamlessly. This process creates the final rigid-flex board. A very important link should be that the rigid-flexible PCB is difficult and there are many details. Suppliers usually perform a full inspection before shipment to protect their own and the buyer’s financial interests.
Advantages and disadvantages:
Advantages: The rigid-flex board has the characteristics of FPC and PCB at the same time. Therefore, it finds use in products with special requirements. It has both a certain flexible area and a certain rigid area, which can save the internal space of the product. It is very helpful to reduce the volume of the finished product and improve the performance of the product.
Disadvantages: There are many production processes for the rigid-flex board, the production is difficult, the yield rate is low, and the materials and manpower used are more. Therefore, its price is relatively expensive and the production cycle is relatively long.
