For soldering QFNs at home, I think the easiest way (i.e. the least amount of stuff to buy) is to pre-solder all the pads (center and outside) on the pcb, so you know you have just the right amount of solder on all of them. Then put some flux on them and the part, put the part on the solder, and reflow it with a $20 hotplate from Target.
No paste, no funny vias, no special soldering irons. _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
