However, this is not the right tool for soldering/desoldering BGA chips (the chip will move, and you can't reliably melt the balls without overheating the chip or the board anyway). The best way is to use an IR soldering station with a temperature profile. The cheapest way is to use a small toaster oven - you can watch the temperature with a thermocouple, or you can set a profile in an automatic controller.[/QUOTE]
There are toaster oven ramp controller kits for doing pcbs.
