Use some heat-tape and cover all areas of the mainboard, exposing ONLY the IC for removal. Using a kitchen pancake/food griddle, preheat the board to 275 for about 10 minutes.

Remove IC with heat gun. Buy some tin/lead solder paste, like Zephaste.

Turn off griddle, let board cool down

Wick up all solder from board after IC removal. Take the solder paste and apply a thin bead across all IC pads on the board. And i mean a THIIIN bead. you dont want too much, as it will bridge and short during a reflow, you dont want too little either or some pins may not connect

Place the chip into place. then use a small nozzle fitting to heat gun, and carefully go around the IC with the hot air nozzle. the paste will melt and reflow new solder on the IC

a reflow/rework station is about $132 bucks on ebay right now. Yellow faced, VFD display, etc...
