Homebrew PCBs

I would have thought the multi-core was better too, I was surprised by
the results I had. You have my sympathy on the Lead-Free. I don't know
about anyone else, but me and Lead-Free haven't gotten along to well
so far. Outside of plumbing (the no lead plumbing solder seems to
still sweat pipes just fine) I haven't liked the lead-free results. It
just doesn't seem to reflow like the tin-lead does. Takes a lot more
heat which crusties up the tip faster and also is hard on some of my
boards. Sure not like the Kester '44'.  Maybe I need to switch to
using a torch for the pcb's too ;-)
