PCB circuit boards are the most primitive cardboard in the initial stage, such as the old-fashioned radio, and now in the production of circuit boards are mostly hard boards, can also be processed according to the actual needs of some special boards. And polyimide or polyester film is also one of the common types of board, this kind of FPC board flexible circuit board reliability is extremely strong, excellent in the manufacture of flexible printed circuit board, then how to ensure the quality of FPC board flexible circuit board processing?

How does FPC board flexible circuit board ensure machining quality?

1. The most practical FPC boards are known to have relatively high wiring density, but they are lightweight and bend-resistant. The best quality FPC versions are used in mobile phones, tablets and notebooks used offline. They are compatible with lightweight electronic products. In order to ensure the overall quality of the FPC version, the core of such circuit boards is Layer is an ultra-thin polymer film, the first step in the production of adding FPC board is to cut the polymer film into a uniform rectangular sheet, and then use a laminate to isolate.

2. In order to make the FPC board adhere to an organic whole, it needs to be sent into the vacuum pump box to make the layers bond tightly. Generally speaking, it needs to be processed for several hours in the high temperature and high pressure chamber. At this time, there is a thermal activation adhesive coating on the polymer film of the middle layer of the FPC board, so that the purpose of combining the FPC board and substrate can be easily realized.

3. If we want to ensure the most stable processing quality of the FPC board is far from this, after stacking the board, we must scientifically cut and cut into a fixed size of the board, and use high-tech equipment to drill holes for later assembly preparation, through the film machine on the board surface of the fourth layer of photosensitive film, FPC board Processing must draw the integrated circuit diagram with the computer according to the needs of users.

Finally, the key step of the FPC plate plate is to put the board into the exposure machine, and use the automatic equipment and computer to scan the controller with the photosensitive laser. Then the surface of the photosensitive layer irradiated by the equipment will gradually improve the hardness. The reason why the FPC plate has strong acid wash resistance is that it benefits from this step. After finishing the above items, the FPC version should be optimized before it can guarantee its overall processing quality.
