Knowledge of rigid-flex boards

What is the knowledge of rigid-flex board?

The birth and development of FPC and PCB has given birth to a new product of rigid-flex board. Therefore, the rigid-flex board is a circuit board having a FPC characteristic and a PCB characteristic formed by a process in which a flexible circuit board and a rigid circuit board are pressed together and assembled according to relevant process requirements.


Production Process:

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 electronics engineer draws the line and shape of the flexible board according to the requirements, and then delivers it to the factory that can produce the rigid-flex board. After the CAM engineers process and plan the relevant documents, the FPC production line is arranged. The FPC and PCB production lines are required to produce PCBs. After the two rigid-flex boards come out, according to the planning requirements of the electronic engineers, the FPC and the PCB are seamlessly pressed by the press machine, and then through a series of detailed steps, the final process is completed. A combination of rigid-flex boards. A very important link should be difficult for the combination of rigid-flex boards, and there are many details. Before shipment, it is generally necessary to conduct a full inspection, because its value is relatively high, so as to avoid the loss of related interests between the supply and demand sides.


Advantages and disadvantages:

Advantages: The rigid-flex has both the characteristics of the FPC and the characteristics of the PCB. Therefore, it can be used in some products with special requirements, both a certain flexible area and a certain rigid area to save the internal space of the product. It is of great help to reduce the volume of finished products and improve product performance.

Disadvantages: The production process of soft and hard composite boards is numerous, the production is difficult, the yield is low, and the materials and manpower are more. Therefore, the price is relatively expensive and the production cycle is relatively long.
