FPC circuit board design needs to pay attention to issues [Copy link]

FPC stands for flexible circuit board, flexible printed circuit board, flexible circuit board, abbreviated as soft board or FPC; it has the characteristics of high wiring density, light weight and thin thickness. So when designing FPC circuit boards, in order to use them better, what requirements do we need to follow? Let's follow us one by one to understand. Generally speaking, the thickness of the board will be affected by the number of signal layers, the number and thickness of power boards, the aspect ratio of the aperture and thickness required for high-quality punching and electroplating, the length of the component pins required for automatic insertion, and the type of connection used. Designing the size of the FPC soft board Regarding the size of the electronic board, the main optimization choice is based on the application requirements, system box size, circuit board manufacturer's limitations and manufacturing capabilities. In addition to the above two factors, in order to minimize the chance of distortion of the FPC soft board and obtain a flat finished board, the layering of the FPC substrate should be kept symmetrical. That is, it has an even number of copper layers and ensures that the copper thickness and the copper foil pattern density of the board layer are symmetrical. Therefore, in order to ensure the normal use of circuit boards, the above steps need to be followed when designing them.

Pay special attention to the edges of the flexible board. After all, it is a connected device and is easy to break. The design of the plug-in edge is very important.
