So I’m still a beginner in microsoldering but I like to experiment with boards. This is how I learn. I have a board here that was working perfectly fine but when a friend of mine want to put the logic board in a new backcase and he powered the phone one, it showed the temperature warning and I felt that the left/long side of the logic board got very warm. i was inspecting under my microscope because I thought this might of been the power button connector which might be bended or something but i think it might be screw damage, can anybody tell me for sure? I will post pictures I appreciate your help and support the screwholes warm up the most and immediately cool down when i disconnect the battery
I have seen worse screw holes than that. The only one to be concerned about would be BS0402 I think it has two voltage lines under or beside it 1V8 and a 2V line. The other screw holes I think just have a ground plain. If you are just learning or an experienced repairer the next step would be to put the board into another known good housing with a known good screen. If it is still throwing out the temp warning start checking your voltage lines.
