Reflow Audio Ic and CPU problem
Hi friends, I wanted an opinion, unfortunately iPhone 7 with audio chip problem there are really too many around, although I have a good success rate with a Reflow this time it went wrong. The phone does not turn on, I have an absorption of 0.4A from the cable but nothing appears on the display. Disassembled I noticed that the lines "PP_Soc_Var" "PP_CPU_Var" and "PP_GPU_Var" are all in short. So I think the processor is the problem ... I had used a high temperature tape to cover the rest of the logic board leaving only the Audio chip uncovered, with a temperature of 310C. I'm really baffled, I didn't think it could go so bad ...
Is dit een goede vraag?
