Advice on Desoldering an IC

[Mike Katz]

I have to second this comment.

I learned to solder in the early 70s building kits and again 
professionally in the early 80s.

In the early days of thicker circuit boards (2 layer only).  A solder 
sucker and solder wick would work.

However, the most expedient and safest way in terms of potential board 
damage, is to cut out the bad chip, then take the pins out one at a time 
and then suck and wick out the holes.

This presents the smallest risk of damaging traces or the plating inside 
the holes.
