What to do when the FPC connector encounters scratches？
In the industry, FPC connectors are also known as flexible printed circuit boards. Generally speaking, they are made of soft materials into pcbs, mainly 0.5mm pitch products. 0.3mm pitch products have also been widely used. When customers purchase FPC connectors, they will inevitably encounter scratches during use, so do you know what to do when the FPC connectors encounter scratches?
There are five main points for the solution when the FPC connector encounters scratches, as follows:
1. The simplest solution is to ask the mold factory to make some transparent casings. After installing the whole machine, observe the movement state of the FPC in the via hole, find the interference position between the FPC and the shell, and solve the problem by changing the length of the FPC. the question.
2. The most traditional solution is not when there is no FPC sample, we can print out the FPC2D drawing paper 1:1 (the paper should be as hard as possible), cut out the shape, install it in the mobile phone, and replace the FPC to find and Analyze and solve problems. Or you can ask the FPC connector manufacturer to make some FPC blank samples without wiring and only the shape, and install them in the mobile phone for analysis.
3. A layer of foam can be pasted on the FPC where it is in contact with the aperture, so that the housing will not directly contact the FPC during rotation, thereby reducing damage to the FPC and increasing its lifespan, but the method is a temporary solution. I feel that it is best to find the reason from the design itself to truly solve it.
4. In order to avoid scratches between the FPC and the casing, it is often used abroad to install an iron shaft in the casing, and the FPC is fixed on the iron shaft to avoid collision and wear between the FPC and the casing when opening and closing the flip.
5. There are many flip + rotating mobile phones. When choosing FPC, first consider wrapping the PFC on the shaft (method 4 above), or simply use coaxial cable instead of FPC to avoid FPC being easily twisted and broken. happened.
