Analysis of the advantages and disadvantages of flexible and rigid boards

The birth and development of FPC and PCB gave birth to the new product of flexible and rigid board. Therefore, the soft-rigid board is a circuit board with FPC characteristics and PCB characteristics formed by combining flexible circuit boards and rigid circuit boards according to relevant process requirements through lamination and other processes.

Rigid-flex board production process

Because the flex-rigid board is a combination of FPC and PCB, the production of flex-rigid 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 needs, and then sends it to the factory that can produce the flexible board. The CAM engineer processes and plans the relevant documents, and then arranges the FPC production line. FPC and PCB production lines are required to produce PCBs. After these two soft boards 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 after a series of detailed links, the final production is completed. It has become a rigid-flex board. A very important link, because the flexible and rigid board is difficult and there are many details. Before shipment, a full inspection is generally carried out, because its value is relatively high, so as to avoid the loss of related interests between the supply and demand sides.

Advantages and disadvantages of flexible and rigid boards

Advantages: The rigid-flex board has both the characteristics of FPC and the characteristics of PCB. Therefore, it can be used in some products with special requirements. It has both a certain flexible area and a certain rigid area, which saves 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 input materials and manpower are more. Therefore, the price is relatively expensive and the production cycle is relatively long.
