Yes, heat on electronics is like a swear word.... bad :-(
Maybe I'm lucky, but I have never fried a chip using the foil and heat gun
method (and I have done alot).
The trick is to blow the heat at an angle to the side of the chip at the
solder joints going around and around in a circle. Never directly on top.
If that makes sense.
