Actually I would make an argument against using a general purpose heat gun to reflow a motherboard. It's easy to exceed maximum temperature of component and fry everything using a high powered heatgun, where as it's much safer to use a hair dryer, which cannot generate too high a temperature. Of course, electronic quality heat guns are different story, as these allow temperature to be controlled precisely. But this is just a warning from my experience of frying multiple motherboards using a general purpose heatgun, despite constantly monitoring the board temperature with IR thermometer. I even physically melted a bga chip down, even though my IR thermometer never indicated temperature above 160 degrees C!! So extra precaution is in order when attempting to use a general purpose heat gun for reflowing motherboards without fine control over temperature output.
