There have been peojects in Elektor and Circuit Cellar Ink (IIRC) to
convert small versions of that device into SMD soldering units. The one
in Elektor claimed it would do BGA devices. Basically, you replace the
thermostat with a microcontroller acting as a PID controller with a
thermocouple sensor.
It is recomended if you do this that you don't use the device for its
original application. Lead (from solder) in the products it was designed
for, or greases/fats on your SMD boards don't help.

Good for baking stuff that's been spray-painted, too, and for drying
plastic sheet prior to impact or thermoforming. Essential for
polycarbonate and some types of Perspex. If it's the type with a fan,
it's also good for the actual thermoforming, though you can also use
your infrared heater for that.
