Robert: I use flux past to weaken the soldering joints and it helps to take off the IC without burning what beneath it of course with some heat..

In reply to Waleed Rishmawi.

Yeah, I need to build myself a heat table to heat the backside of the PCB to make removing the bottom center-grounded IC's easier. But I don't think it will help for IC's that use adhesive. We need to figure out what chemical that we can safely use to help weaken the adhesive.

Robert: yeah, most of the time and sometimes I see solder beneath it and that is why I applied heat..I guess I applied too much of it.

In reply to daniel suo.

Daniel: not, actually it was taken out of a similar board and the same exact part number.
