How to solve the problem of FPC connector scratching and what are its
characteristics?
1. You can let the mold factory make some transparent shells, and observe
the movement state of the FPC in the through hole after installing it into the
whole machine, find out the interference position between the FPC and the shell,
and solve it by changing the length of the FPC.
2. An older method is that when there is no FPC sample, we can print the
FPC2D drawing with paper 1:1 (the paper should be as hard as possible), and cut
the FPC2D drawing to 1:1 (the paper should be as hard as possible) Harder), cut
the phone into an outer shape. Or let the manufacturer make some FPC prototypes
with no wiring and only appearance, and install them in the mobile phone for
analysis.
3. A layer of foam that is in contact with the aperture can be attached to
the FPC, so that when the FPC rotates, the shell will not directly contact the
FPC, thereby reducing the damage of the FPC and extending its service life.
However, the method has a feeling that it is not a cure for the symptoms, and it
is recommended that the design itself be used to find the cause to really solve
it.
4. In order to avoid scratches between the FPC and the shell, an iron shaft
is usually installed in the shell in foreign countries, and the FPC is fixed on
the iron shaft to avoid collision and friction between the FPC and the shell
when the cover is opened.
5. Nowadays, when choosing FPC for many flip+rotating mobile phones, first
consider winding FPC on the shaft (method 4 above), or simply use coaxialcable
coaxial cable instead of FPC to avoid the problems of FPC being easily twisted
and broken.
While 5G is becoming more and more popular, the mobile phone industry is
also a huge market. In addition, its applications have been extended to
industrial fields, such as instrumentation, automotive electronics, medical
equipment, military equipment, etc., due to emerging applications. Demand
continues to grow, and the annual growth rate of this industry will reach 8-10%.
What is the reason why FPC connectors are widely used? What are its
characteristics? The main points are as follows:
1. Miniaturization of production, small and high-density integration.
2. Small size, saving space.
3, light weight.
4. Good flexibility, flexible application and foldable.
