When doing this I typically use a very small and controllable butane torch with tin foil as a heat shield over nearby components. Even then I always communicate to the person that the repair is intended to facilitate RECOVERY ONLY and that all bets are off on the machine being long-term usable again. Usually this is only useful for large BGA chips. Unfortunately Apple laptops made the past 10 years use BGA chips almost exclusively through logic board design.
