Stick high-temperature tape around the touch module on the replacement screen. Then wrap the screen with protective film.
Now we will grind the touch module with the electric chip grinding tool.
Be patient during the grinding. Start with the top layer then move on to the next layer. Also, be careful not to damage flex cables nearby.
With solder joints coming out, stop the grinding work. Clean the bonding pad with PCB Cleaner soaked cotton swap afterwards.
