When it comes to repairing the green flex of iPhone x, I believe what I hear most is that it is difficult to press and the yield is low. What's the matter? Before unlocking this problem, we should find out which kind of cable can be pressed.
The first case: backlight screen broken row can be pressed, but the value of the screen is low, maintenance is troublesome;
The second case: the cold light screen can be pressed as long as there is no corrosion in the liquid crystal water and the line is broken;
The third case: curved screen broken drainage water does not show can also be repaired;

Broken Flex

The fourth type is also the key point we are going to talk about today-Apple X and above flexible screens, this kind of screen is broken and water enters and causes no display or IC breaks, which can be pressed but the maintenance is difficult. If the operation error is caused by the process of removing the bracket/cover If the screen has lines such as green lines and white lines, it cannot be repaired, and it is squeezed by external forces, such as the screen falling to the ground or squeezed out of the trouser pocket. The repair yield is very low. This type of drop and extrusion is generally The green line or the big white line, the small pink line has the highest repair yield but not 100% can be repaired.

It is not difficult to see from this that repairing the Apple X green row is not an easy task, and we must start with the repair process.

The first disconnection of the cable, because the Iphone x LCD terminal connected to the green terminal is flexible, the integrity of the circuit must be ensured when disassembling, a little care will cause damage to the circuit; in addition, the Iphone x is a flexible circuit, so turn it over There is a risk when starting the screen cable, because it is a PCB board that extends from the screen and has many lines, which requires suitable temperature and skilled techniques.

Soft Flex

In short, when removing the cable, the cable should not be subjected to force such as folding, topping, or warping. At the same time, uneven strength will also affect it. Therefore, when removing the cable, use a special tool to remove it and master the strength.

For the second cleaning aspect, the Iphone x green line is very delicate and fragile. Use the special potion for Apple X line to clean with gentle strength. In addition, nano sponge and cotton swabs are relatively rough, so you must use very soft cleaning consumables when cleaning. Clean the line.

The third alignment, because the Iphone x cable is bent to the back of the screen, the cable cannot be kept level with the screen after flipping, or lines will easily appear. Therefore, it is necessary to maintain a slightly slanted state after flipping for compression. ZWX's new CT-1 press alignment platform is designed for this feature, which can keep the cable in the best condition for pressing and reduce the chance of lines.

Finally, let’s talk about the machine. Since the Apple X green row and the extended PCB board contact positions are flexible and the circuit is very delicate, it cannot be completed without a stable pressing temperature, precise balance and stable body structure. Iphone x green row repaired. The prospect of adopting an integrated steel key structure. ZWX's new CT-1 compressor is not only stable, but also improves the precision of the cable pressing through the heating uniformity of the precision ceramic cutter head, and the adjustable high-power lens on the machine can be perfect Auxiliary circuit alignment, so as to realize the double improvement of the efficiency and yield of the cable repair.

Therefore, in order to improve the yield rate of Iphone x green row, not only must there be a skilled operation method, but also precision equipment including the body, cutter head, and air pressure to assist.
