Because of the progress of the times, the rapid development of science and technology, in recent years the development of electronic and electrical industries in all aspects of the FPC connector applications are becoming more and more widespread, but because the FPC connector is a delicate, easy to break the product, so in the ordinary use of time to be more necessary to avoid FPC connector breakage and some of the problems of the solution. The following is a small number of DIKAI precision for you to explain these problems and solutions!

First, the FPC connector folding process has a strange sound:

1, FPC itself is multi-layer, and with the inner wall of the hole in the cover has been interfered with, so in the flip-flop, can always hear the noise. We can let the manufacturer tape the multi-layer tied or glued together to look like a layer, but in the winding and folding part of the best not to be glued together, retaining the multi-layer structure, but also can reduce the length of the FPC.

2, FPC in the shaft hole length over the diameter of the hole (when the cover is closed, there is no interference), but in the flip to a certain angle, FPC will have a twisting process, it will touch the inner wall of the hole, we can hear the noise. At this time we can reduce the length of FPC to ensure that the folding is not scratched with the inner wall and can work properly.

Second, the FPC connector and the shell have scratches:

1, in order to avoid FPC and shell scratch, foreign practice is often installed in the shell of an iron shaft, FPC fixed to the iron shaft, to avoid opening and closing the cover when the FPC and shell collision, friction.

2, can be in contact with the aperture on the FPC paste a layer of foam, so that when turning the shell will not be directly in contact with the FPC, thus reducing the damage to the FPC to increase its life. However, this method has a kind of symptomatic feeling, it is best to look for reasons from the design itself to achieve a real solution.

3, you can let the mold factory to do some transparent shell, installed after the machine to observe the FPC in the hole in the state of motion, to find the FPC and shell interference position, by changing the length of the FPC to solve the problem.

4, now a lot of flip + rotating cell phone, in the selection of FPC, first consider the FPC around the shaft (method 1 above), or simply use coaxial cable coaxial cable instead of FPC, to avoid FPC easy to twist, breakage and other problems occur.
