This is a 3-pack of reballed audio ic chips for the iPhone 7 and iPhone 7 Plus. This chip also works for the 6s and 6s+, but they aren’t replaced as often as they are on the 7 series. These are good quality reballed chips, which I actually prefer because they use leaded solder, which melts at a lower temperature than the lead-free stuff. This is important because using too much heat on this repair causes “searching/no service” issues. The less heat that is used, then the better success rate without complications.
