How to solve the scratching problem of FPC connector?

I. How to solve the FPC connector scratch problem?1, you can let the mold factory to do some transparent shells, installed after the machine to observe the FPC in the hole in the state of motion, to find the FPC and the shell of the interference position, by changing the length of the FPC and so on in order to solve the problem.2, one of the oldest way, not in the absence of the FPC samples, we can use the FPC2D drawing with a paper 1:1 printed out (paper should be as hard as possible electronic connector some), cut out the shape instead of FPC to find and analyze the problem. (paper should be as hard as possible electronic connector some), cut out the appearance, loaded into the phone, instead of the FPC found and analyzed to solve the problem, or you can let the FPC to do some no alignment, only the shape of the FPC blank samples, loaded into the phone to analyze the 3, you can stick a layer of foam in the FPC on the aperture contact, so that the shell will not rotate directly in contact with the FPC to reduce the FPC damage in order to increase its life. Damage to increase the life of the FPC, but the method of industrial connectors have a kind of treatment of the symptoms do not cure the root cause of the feeling, better or from the design itself to find the reasons can be done to solve the real problem. 4, in order to avoid the FPC and the shell with scratches, the foreign often practice is to install the shell of an iron shaft, the FPC is fixed to an iron axis, to avoid opening and closing of the flip cover when the FPC and the shell of the collision, wear and tear. 5, there are now a lot of flip + rotating cell phones, board to board, the first consideration in the selection of FPC will be the FPC, the FPC and the FPC. In the selection of FPC, first consider the PFC around the shaft (method 4 above), or simply use coaxialcable coaxial cable instead of FPC to avoid FPC easy to distort, fracture and other problems occur.
