No IMEI after Audio IC repair (Intel)
After 10-20 successful Audio IC repairs recently I started failing. I started to get BB CPU issues after Audio IC job.
All the successful repairs so far were done using a preheater set to 170 and Quick 861 set to 380 and 80% air. When I put the board on the preheater I applied flux and when it started to smoke I started using hot air gun. This was my routine so far. But recently using same technique I started getting No Service/Searching issue after. I suspect it is due to BB CPU.
I tried reflecting what I have changed when those repairs started to fail. And the only thing that I could think of is the flux.
I tried calibrating the preheater but it was not far off about 5 degrees.
I am not confident at doing Audio IC repairs anymore. And I have three phones on my table with No Service/Searching issue on my table already.
I would appreciate your help.
