Bummer. I'm not good at desoldering chips without
potential damage
to the board. Joe.
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.
