From the last ten fixes, I have the experience that there is no need to change or rebaling audio ic, just re hot with a good flux paste. Temperature 405 Air 19. Station Quick, flux Kaisi625A Lead-free Solder Paste Flux.

The first one I repair this procedure about November 2018 and not one complaint. Total repaired as 20pcs iP7. Beware, of if the iPhone cannot be started after this fix, you need to reball audio ic. When water damage iPhone, the IC is exchanged.

Reflow doesnt help to fix the broken traces under the audio ic. The iPhone 7 suffers from board flexing and the traces under the ic need to be reconnected with jumpers to make a proper repair.

Paths are just destroyed when you remove the Audio IC. Broken paths are always in the place of shielding that dissipates heat.
