I have also used a very thin feeler gage to do the same trick but no room for that in this situation. Thanks for the hint.

Re: looking for technics to replacing the IC4 FST3253
David,
A Hot Air SMD "Rework" gun is the way to go. And, can be a lot of fun.
Don't be afraid to give it a try, you might find it as much fun as I do. :)

Re: looking for technics to replacing the IC4 FST3253
If you're going to be doing ANY SMD repair, definitely buy a Chip-Quik kit. It comes with liquid flux, which you apply before removing the IC, and before soldering on the new one. As the old IC is

Re: looking for technics to replacing the IC4 FST3253
Agreed. Hot air rework station @$125 is the best investment for removing sm ICs.
No clean flux and solder wick will do wonders for the pads to prep for the new part.
