I think a heat gun would + tweezers would probably be sufficient enough, however, he'll probably need to reference ifixit images to figure out where things need to go. I think it's a bit too difficult to hold a heat gun, an infrared thermometer, a set of tweezers and flux, so I would just get a feel by testing it out with some other busted PCB.
