Reflow vs. hot air station, I was wrong for years

Back when I started fixing boards in 2008, I swore by my $40 heat gun for reflowing cracked BGA chips. Took me three failed laptop motherboard repairs before a guy at a shop in Akron told me to get a proper hot air station. The controlled airflow and temp curve made all the difference, even on older gear. If you're still using a heat gun, what's holding you back from switching?

Man, that Akron guy did you a solid. But here's the thing nobody talks about: a heat gun is actually fine for the board, the problem is what it does to the parts around the chip. I've seen people melt plastic connectors and blow off tiny capacitors because the airflow is like a tornado. A hot air station lets you focus the heat and actually watch the solder melt, its way more precise. Plus you can use different nozzle sizes depending on the chip. What really sold me was when I ruined a $200 GPU board with a heat gun, that hurt worse than the failed laptops. Have you noticed a big difference in how long your boards last after the rework?

Ouch, that GPU story hurts just reading it. Solidarity, man.
