The foil really helps to absorb the heat so nothing else except the chip heats up. I have one that I need to do,
Some general electronics advice: Be careful with the heat. In general components are never rated for exposed to temperatures over 200 C for more than a few seconds as the temperature profiles in data sheets show. There are usually limits on safe temperature rise and fall times as well. LEDs are the most sensitive I've seen so far, but nothing likes 400 C very well.
I would not expect the chip to function well after heated to 370.
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.
If I get time this weekend I will do it and take some picks if you want.
In any case I think that would be great!
Ok, will do.
