Microphone not working iPhone 7. This is a very common failure in Apple devices.

We can also find the case when the iPhone 7 lasts a long time to turn on because of a track that is cracked below the audio IC.


This repair is a bit complicated and we have to lift the audio IC, scrape the track and solve the pad. We have used a JBC air station at 380ºC and 50% air, a JBC power welder, FLUX Amtech, isopropyl alcohol, tin paste, 0.01mm copper wire, tin wire.
If you have any doubt, question or suggestion, please leave your comment above and i ll be glad to answer it!
Thank you for watching!
