preheating SMD parts prior to hand soldering?

1587 1 Sep 12.2019, 17:55:27

If you are doing something funky like hand soldering a QFN package or even doing a ceramic capacitor, does it make any sense to preheat the part prior to soldering to reduce thermal shock? Like on a hot plate. If you have aversion to hot air pencils (its easier to drag solder or use solder channels to route solder into a flat no leads IMO).
