Finally figured out why my hot air rework was always burning pads

I was fixing an old tablet from 2015, trying to lift a tiny chip. For months, I kept getting tiny brown spots on the board under it. My buddy in Phoenix saw my setup and said, 'Your nozzle is way too big, man.' I was using a 10mm tip on a 6mm part, blasting the whole area. Switched to a 5mm nozzle, dropped the temp to 320C, and the next one came off clean. Has anyone else had a simple tool choice mess up a basic job for that long?

Remember my friend who melted a whole row of caps using a heat gun for shrink tubing?

My cousin's garage still smells like burnt plastic from that.
