Knowledge of mobile phone cable

The mobile phone cable is the connection cable between the main board of the mobile phone and the display screen of the mobile phone, and the connection cable between the camera, the key board and the main board is also the cable.

The cable is small in size and light in weight. The original plan for the cable board is to replace the larger wire harness. On the current cutting-edge electronic equipment mounting board, the cable is usually the only way to meet the requirements of miniaturization and movement. Cables (sometimes called flexible printed circuits) are copper circuits or printed polymer thick film circuits etched on a polymer substrate. Regarding thin and light equipment with a compact and messy structure, its planning and processing solutions range from single-sided conductive lines to messy multilayer three-dimensional assembly. The total weight and volume of the cable are reduced by 70% compared to the traditional round wire harness. The cable can also increase its strength through the use of reinforced materials or liners to obtain additional mechanical stability.

The damage of the cable is nothing more than the disconnection and resistance. The former is generally more intuitive and can be found with the naked eye. It can be dealt with by changing or flying the cable; if it is the latter, it is relatively troublesome. One point is only known by demand measurement. However, the display circuit of the parallel port, if the small screen has a display, the display problem of the large screen will not be very messy. Because of the parallel port line, the large screen and the small screen are shared. If the screen has a display, the other is not. There is a problem with the enable signal of each screen, or a problem with the cable interface.
