Yes, that's what I just did with a board from a Dyna dm2400 cnc m/c. The L295 solenoid driver ( used as a stepper driver) had gone down with a few diodes gone with it. Not having sophisticated equipment snipping the leads is the way to go. Board now works a treat and the owner is well pleased - he bought it cheap on fleabay as it was faulty.
I remember the weller attachment, my dad made me something similar in work - it went between the pins and was a solid block without holes - worked well.

A fellow from plant engineering at an auto plant told me how they repaired boards at the plant, where down time is really expensive. They cut the ic from the leads, remove the leads one at a time and then put in a new ic.
It is fast and doesn't damage the board. Of course there isn't any old chip left.

From Tim P (UK)
further to the discussion on removing components
from boards, I remember Weller produced a device
for de-soldering ICs which was like a metal IC socket
on a soldering iron, which went over all 16 pins.
I think it's main problem was that the molten solder
would then short out adjacent pads, needing careful
clean-up. Tim
