You might get the rest off a board with
lots of solder wick, but you'll likely
take a few traces with it...

ChipQuik really works for this, although I haven't personally used it
on larger than 48 pin LQFP devices (and I prefer hot air now, having
gotten the necessary gizmo). It's even possible to re-use the removed
device (after cleaning) if it turns out that the problem was elsewhere
in the circuit (like THAT ever happens).

Not recommended for more than occasional use, since it's relatively
expensive (in the neighborhood of US$5 per foot) and a quad pack
probably takes 2" to 4".

Usual disclaimer: just a customer who buys too many gadgets...
