maybe its in the thread but I missed it.. but..
how do you preheat the bottom of the board?
I get the rework station on low air and a set temp for so long on the top of the chip but what do you use to preheat it? toaster oven ??

If you don't want to buy a specialized pre heater, an electric skillet works great. Something that can get up to 400F. Make sure it's not placed directly on it, prop it up on some screws or what ever you deem suitable. It may not be necessary but it has given me nothing but 100% success putting chips on. Good luck bud, and remember the flux.
You want to preheat the board to prevent flexing cracking large temp differences that break things. Warping or breaking your board would probably ruin your day.
