FYI in the old days when people would salvage chips of
old unmarked cards
a popular way to remove them was a propane torch and pliers! Obviously
the board would get toasted but you could get the chips off fairly clean
and fast. Though once I seriously over did it on the heat. The result
is a old 7400 that is bent some in the middle...it still worked!
My usual practice is to place the board to be unsoldered upside down in the
oven raised above a tray. Heat until solder melts and gravity has it's way.
Fast, neat, clean. Pity you can't speed the process up by using a microwave :-)
