Is there a way to fix the broken screen cable of the mobile phone?

Nowadays, it is difficult to repair the broken screen cable of the mobile phone, and it is basically repaired by directly replacing the screen. Because it is still relatively difficult to replace the cable.

First prepare some cutter heads and flux, then clean the wire connection points of the electronic circuit board, brush a thin layer of flux on the connection port, peel off the wire head coat of the wire to be connected, and brush a thin layer of flux on the stripped wire head, dock with the circuit board to be docked, and then brush a layer of flux, and then reinforce it with adhesives such as silica gel. This repair method is more complex and cumbersome, in order to prevent improper operation and potential safety hazards, you can ask professional maintenance personnel to deal with it.

Cables, also known as flexible circuit boards. It is used for data transmission in moving parts and active areas, such as the data cable connecting the internal motherboard of the computer to the hard disk and optical drive, the data cable connecting the mobile phone motherboard to the display screen, and the data cable between the connected devices are collectively referred to as the cable.

Due to its small size and light weight, the cable strip was originally designed to replace the larger wire harness wires. Cables can be moved, bent, and twisted without damaging the wires, and can be adapted to different shapes and special package sizes. The only limitation is volumetric space.

Because they can withstand millions of dynamic bends, cable cables are well suited to inline systems that move continuously or periodically, and become part of the final product functionality.

How to save the phone cable when it is broken, I will tell you the principle.

The flying wire is broken, and the general welding can be completed by skilled hands.

You can go to the mobile phone store for replacement and repair.

Changing the cable will do.

The damage of the wire is nothing more than two aspects of wire breakage and resistance, the former is generally more intuitive, and can be found with the naked eye, replaced or flying wire.

It can be solved; If it is the latter, it is relatively troublesome, and it needs to be measured to know. It has nothing to do with the screen, and there is no need to change the screen.

The cable is connected to the mobile phone motherboard to the mobile phone display, and the connection cable of the camera, button board and motherboard is also the cable. On the inside of the screen, after changing the cables, use a knife to flatten and widen the case at the place where the cables pass. In this way, the repair rate can be greatly reduced.

The phenomena caused by the broken cable of the mobile phone are:

1. The screen imaging is not clear, and the pattern is flashing;

2. Or simply the mobile phone screen is not lit;

3. In addition, the cable of some slide phones will be damaged, which will cause the camera to not work properly.

Everything you see on the display is controlled by the motherboard, and that's where the cables come in. It is responsible for the data transfer between the motherboard and the display of the phone. The mobile phone cable has the characteristics of small size and light weight, and its faults are manifested in the blurred screen, no display, no light, etc.

Summary. Dear, it can be repaired, and it can be repaired if the mobile phone screen cable is broken. The cable is the connection cable between the mobile phone motherboard and the mobile phone display, and the connection cable of the camera, button board and motherboard is also the cable.

The damage of the wire is nothing more than two aspects of the broken wire and the generation of resistance, the former is generally more intuitive, it can be found with the naked eye, and it can be solved by changing or flying wires; If it is the latter, it is relatively troublesome, and it needs to be measured to know.

You're a little broken, but as long as it's not big, it can be repaired.

How to fix it. 1.First fix the cable and wipe the cable clean2

Use a tool such as tweezers to flatten the broken position at the end of 3After flattening, use fingerprints to repair the flying wire, compare whether the broken wire and the flying wire are about the same width, only the same, too thin affects the stability of the signal, too thick is not good for welding. In addition, it is necessary to find the position of the line, like the light yellow vertical line in the figure is the gap of the line, not the line, and the golden line is the line.

4.Find a suitable position at both ends of the cable break to scrape the surface protective layer. Pay attention to a trick is to scrape different wires as far away as possible, not too close, otherwise it is easy to connect tin when welding flying wires, resulting in the waste of previous efforts.

5.After that, the operation is the same as repairing the fingerprint. Put the soldering oil -> plating a layer of low-temperature tin-> the flying wire is coated with a layer of tin, and then soldered.

The place that needs to be paid attention here is that the temperature of the soldering iron cannot exceed 300 degrees, and if the temperature is high, it is easy to split the already broken cable. Causing irreparable damage. Therefore, be sure to lower the temperature, preferably slightly higher than the melting point of the solder.

Connect it this way.

If it hasn't been repaired, it is recommended to find a nearby electrical repair worker to get it.
