Would you be so kind as to give me a couple of part numbers so that I can check
out the specs?

I've hand soldered SMT devices to boards, but you describe a technique that I
haven't used--"use a flux pen to wet solder wick and use that to remove the
excess solder from the pins". That sounds really clever--how exactly to you
"wet solder wick?" I've been trying to be so compulsive, this may help my
sanity ;)

Thanks, David. I use gEDA and have fab houses build the boards, but I've been
so into the whole breadboard it all up first concept that I hadn't really
thought how cost effective it would be to hybrid breadboard/circuit fab. What
a great idea.
Thanks,
Craig
