Flameless torch... typically disguised as butane soldering irons. Remove the tip and you have a ceramic grid heater element (catalyzer?) that converts the flame to just glowing red heat. There is enough air flow to target small areas. Also does wonders for de-stringing. These are usually hand held.

But the surface mount components for PCB's using flameless heat tools... now that's professional grade! I use my flameless hobby torch for making printed board assemblies.
