Some strategies on the design of fpc flexible circuit board

Fpc flexible circuit board is also called fpc soft board. It is a flexible PCB that can be bent. It is also relatively fragile, and it is easy to break if it is designed slightly incorrectly. As far as design is concerned, today I will introduce some relevant knowledge points about fpc flexible circuit board design.

The width of Fpc flexible circuit board in design is related to pin line width, line spacing and pin number. If there are more pins, the fpc will naturally be wider. This is for single panel, we can also replace single panel with double panel to reduce the width of fpc. The Fpc soft board has good flexibility, and there is a margin when designing the fpc length, so there is no need for complete precise calculation. On the premise of not affecting the performance of the fpc, the appearance design of the fpc is also very important. When designing the appearance, we need the gap between the fpc soft board and the B/C parts and vias to fully satisfy the B/C part wall In the case of thick and strong, try to leave more space for the fpc circuit board, which is also a very important part of our design.

When we use Pro/E to design FPC soft boards, do not use part-solid modules, but sheet metal modules. Why do you say that, because in the sheet metal module, the fpc soft board can make the fpc appearance that is closest to the real thing. Fpc bending and flattening are easy, and the modification is also simple. It can simulate the FPC in the most realistic way. The theoretical real position in the hole. ?

The above introduction is only some knowledge of the structure of fpc flexible circuit board design, and does not mention some hardware-related indicators. When we are really designing, we need to combine the hardware to make the most perfect design.
