Chris,

If you do not need to save the pic then easiest way is to cut
Pic's pins from top then remove them one by one. If you need
To save the pic too you are going to need 2 soldering irons.
DO this

solder all pins together on both sides have some one
ready to pull the pic from the other side.
take both soldering irons and start heating both sides
at the same time and move your irons back an forward let
the person slowly pull it. I was able to remove 40 pins pics
without any damage. You need to do this fast

I really despise PTH's in boards. However, I have some 40 pin PDIP PICS
soldered into thru-hole proto boards that I need to remove. The boards
are
prototype quality with mask & silk, etc, but I notice that this
particular
vendor's copper tends to de-laminate very easily when re-working. I need
these boards to survive without visible scars. Solder wick is out,
likewise
my inexpensive suction type tools since they tend to lift pads when
enough
heat is applied to get the solder out of the barrels.

What is the safest and surest way to remove these chips? I will gladly
buy
another tool, as long as I won't need a new mortgage to pay for it...

please, HELP!

Chris
