I just skillet-soldered an Atmel flash IC in an 8-CASON package (leadless -- absolutely no exposed metal when mounted) for the first time, and while I don't have the tools to electrically test or program the PIC here at home, it appears to have worked. I'm very surprised at how easy it was, but I shouldn't be too proud until confirming that everything actually works. I was just thinking the same would work for BGA, though. I'll post a few photos to my site and send the link to this thread later. Anyone with any actual experience in doing BGA's in this way? -n.
