So I'm a newbie using the hot-air station (cheapie from China), and am possibly having issues properly soldering on a QFN package (i.e. BQ24780S) on a laptop motherboard, where most of the pad is under the chip.
When I look at the repair under a scope it looks fine to me, but when I apply power, I'm getting various different results each time I try to re-flow or replace it. I know it takes practice, and am willing to do it, just want a good reference video to verify I'm doing it correctly.
Does anyone have a link to a favourite YT video that they think is the proper way to replace a chip similar to this?
