I use that trick to get parts off board where I don't care about the board.
Sometimes I apply a propane torch. I get good parts but the boards a mess.
I use a solder pot, originally designed for mass-production wire tinning, but
if you overfill it, creating a menescus of solder, you can refloat the boards
a bit at a time and pull the parts off with tweezers.
The solder pot is thermostatically controlled, but the solder mass is a bit
thermally sluggish. I usually have to take a break after a couple of passes
and let it equilibrate.
I was astonished to find bar solder at Fry's. Sold by the pound bar, right
out on the shelf with the other prototyping supplies.
