Repair iPhone 6 Plus ”Touch Disease” Issue

When your iPhone 6 Plus suddenly touch no response, and the it shows a flashing gray line., what should you do？ If you don't want to spend too much money on a cell phone repair shop, you want to save some money can follow this article in the following detailed description of how to solve the touch and flashing gray lines. 




Repair Process:

1. disassembling the iPhone and removing the iPhone 6 Plus motherboard to access the touch IC's that reside on the back of the logic board. 

2. Once the motherboard has been removed, the next step is to use a hot air station to carefully remove the Meson U2402 integrated circuit.  


3. Removed the Meson IC, its best to clean the pads with leaded solder to remove the manufactured-applied unleaded solder. 

4. After the pads have been cleaned and prepped for a new IC, its time to add some flux so the new pre-balled IC has better luck sticking to the solder pads.

Once we align and reflow a new Meson IC to the motherboard, we will affix a "future-proof" shield by soldering a metal shield onto the housing so it strengthens the area around the touch ic's. This will lessen the chance that the device will come back for any more issues.  


5. After use cleaning tools and testing the motherboard after re-assembly. We monitor the touch with a special program to calibrate the screen. Once we confirm the phone is fully functional again and regained touch sensitivity on the screen we will mark the repair as successful.
