U8100 was damaged due to water damage. I did not find CPU shorts but who knows. No water under U8100 but damage to a few caps in the area.
Unit would not engage 20v

I pulled U8100 in an attempt to split ball it which was unsuccessful. So I need a replacement. I don't trust the one I have.

Question: Can these be changed or is there some apple voodoo that married it to the machine? If they can be changed were do I find them. I was unsuccessful split balling this when I pulled so I am sure I would fail with a donor as well.

Is the PMIC married to the board like a T2?
I change chips like this all the time on ipads. Ipad 8th gen PMIC is common and I pop them on and off in 5 minutes.

I just don't want to stencil one to find out they are married. I am not able to split ball these. Too many balls just a little too big
