The easiest way to not damage the board is to cut the leads to the chip,
and then use a solder sucker to remove the solder in the hole along with
the remnants of the chip leads. Hopefully if one or more of the leads is
soldered to the ground plane, those pads used thermal isolation to
separate them from the ground plane.
Hi
In most cases, I find that heating from one side and sucking
from the other works fine, even for ground planes.
If I can get the solder to melt at all, it always clears this
way.
As another mentioned, if it only has a little solder in
it, you need to add solder to fill the hole before sucking.
Solder wick is almost impossible to use in such cases
without damaging the board ( too many heat sinks ).
