PCB News - Rigid-flex board

The essence of the rigid-flex board is to use the FPC as one or two circuit layers of the PCB, and then partially mill the rigidity of the PCB, leaving only the flexible part. What is the rigid-flex board? The birth and development of FPC and PCB gave birth to the new product of rigid-flex board. Therefore, the rigid-flex board is the flexible circuit board and the rigid circuit board, which are combined together according to relevant process requirements through pressing and other processes to form a circuit board with FPC characteristics and PCB characteristics.

The birth and development of FPC and PCB gave birth to a new product of soft and hard board. Therefore, the rigid-flex board is the 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.

Because the rigid-flex board 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 electronic 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 hard 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. After these two soft and hard boards come out, according to the planning requirements of the electronic engineer, the FPC and PCB are seamlessly pressed by a pressing machine, and then a series of details are passed through. Become a rigid-flex board. A very important link, because the rigid-flex board is difficult and there are many details, it is generally inspected before shipment, because its value is relatively high, so as to avoid the loss of related interests between the supplier and the demander.

Advantages: The rigid-flex board has the characteristics of FPC and PCB at the same time. Therefore, it can be used in some 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 of great help 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.
