One that i have done quite a few of lately was drop damage iphone 6 and 6 plus with no touch. Customers come in for screen replacement of course. Most of these are touch IC chip issues and after talking to a friend with 1 way they did it, i decided to try my own method. Sure enough aside from 1 6+ that was bent pretty badly, all the others that i reflowed the the touch IC chip were recovered with no issues.
