LCD Touch screen For iPhone 13Pro

         The solution to the failure of the mobile Phone Touch Screen and the application of the shrapnel microneedle module

1. The touch screen and buttons of the mobile phone are all out of order

Solution: Add soldering or replace the touch IC, add soldering or replace the CPU, write software

2. The touch screen of the mobile phone fails, but the buttons are normal

Solution: Replace the touch screen, add welding or replace the touch IC, install the CPU, check for broken wires or short circuits

3. The touch screen of the mobile phone is biased, and it is still biased after calibration

Solution: restore the factory or the grid code chip, deliberately correct the deviation during calibration, and replace the touch screen

4. The calibration screen appears when the mobile phone is turned on, but the calibration cannot be completed

Solution: Replace the touch screen grid chip, write the full character library, install the CPU, add soldering or replace the touch IC, check whether there is an open circuit in the components around the touch IC, and replace the cable

5. The touch of the mobile phone fails, the disassembly is normal, and the installation fails

Solution: The four sides of the touch screen of the mobile phone are too tight, remove the sealing strip, the root of the touch screen lead is broken and virtual connection, and the related components of the motherboard are soldered

Test its current transmission capability and ability to withstand voltage. As a connection module, the high-current shrapnel microneedle module can transmit and conduct current within the range of 1-50A. It has strong over-current capability and stable connectivity. In the field of small pitch, there is also a reliable way to deal with it, which can adapt to the pitch value between 0.15mm-0.4mm, and there will be no broken needles or stuck pins. The average service life can reach more than 20w times, and there is no need for frequent testing. Replacement effectively saves time and material costs.
