Because of the progress of the times and the rapid development of science and technology, the development of various aspects of the electronic and electrical industry in recent years has made the application of FPC connectors more and more extensive. However, because FPC connectors are delicate and fragile products, they are usually used It is more necessary to avoid FPC connector breakage and solutions to some problems. The following is the editor of the Kaboer FPC manufacturer to explain these problems and their solutions.
Abnormal noise during FPC connector turning
1. The FPC itself is multi-layered, and it interferes with the inner wall of the hole when the cover is closed, so abnormal noises can always be heard when the cover is flipped. We can ask the manufacturer to tie up the layers with tape or glue them together to look like one layer, but it is best not to stick together in the folded part, keep the multilayer structure, and also reduce the length of the FPC.
2. The length of the FPC in the shaft hole exceeds the aperture (no interference when closing the cover), but when it is opened to a certain angle, the FPC will have a twisting process, it will hit the inner wall of the hole, and we can Hear abnormal noises. At this time, we can reduce the length of the FPC to ensure that it does not scratch with the inner wall when it is folded and can work normally.
The FPC connector and the shell are scratched
1. In order to avoid scratches between the FPC and the shell, a common practice abroad is to install an iron shaft in the shell and fix the FPC to the iron shaft to avoid collision and friction between the FPC and the shell when opening and closing the flip.
2. A layer of foam can be attached to the place where the FPC is in contact with the aperture, so that the shell will not directly contact the FPC when rotating, thereby reducing the damage to the FPC and increasing its life. However, this method has the feeling of treating the symptoms rather than the root cause, and it is best to find the reason from the design itself to achieve a real solution.
3. You can let the mold factory make some transparent shells. After installing the whole machine, observe the movement state of the FPC in the through hole, find the interference position of the FPC and the shell, and solve the problem by changing the length of the FPC.
4. Nowadays, when choosing FPC for many mobile phones with flip cover and rotating, first consider winding FPC on the shaft (method 1 above), or simply use coaxial cable instead of FPC to avoid the problem of FPC being easily twisted and broken. happen.
