Quite a bit of the iPhone production is automated from what I understand. Basically many of the sub components before they get to Foxconn for final assembly have huge chunks automated. Apple uses a lot of automation and people. Their idea is to use the combination of both to hit the highest quality mark they can get. Some companies will basically accept some fall off in quality because they can automate more things and save time and or money, but apple tries to get the best of all worlds. It’s not an accident that when you get your phone it has almost assuredly no defects electrically, mechanically and cosmetically. Of course they aren’t perfect but they do try hard to be close to it.
