Oh I've done it successfully, I just don't like it. lol
These boards at least don't have a bunch of electrolytics to heat up and pop anyway, and if I'm removing chips that are malfunctioning anyway no risk overheating them and killing them.... But yeah, I still don't like hot air. I got both of those chips off with just a soldering iron.
I recently had to do some really detailed rework on an incredibly rare/irreplaceable board in a Sony CRT projector. There was just no way I was using hot air on that, but chipquik got it done!
-Cheers!
