Any one tried a Skillet rather than Toaster Oven?
I know a rather skilled tech who uses a hot plate for putting down QFN
packages. These are the ones with a large ground pad completely
underneath the part.
He uses small syringes loaded with solder paste. These are sold for
this purpose. Then it ties into a foot pedal which controls compressed
air. The whole thing lets him quickly put solderpaste on the board
manually. Then stick the part on and reflow. I've not priced the foot
pedal, but the actual applicator tips aren't too expensive. They are
considered to be consumables.
