Now we need to solder the reballing-finished touch module onto the replacement screen.
Before soldering, insert a pry piece under the touch flex cable. For better operation, we can apply some alcohol here. The metal plate and paper are used here for heat insulation. So that the screen won’t be damaged by high temperature during soldering.
Apply some paste flux to the bonding pad. Get the touch module in the right position. Solder with Hot Air Gun.
