[dorkbotdc-blabber] Soldering tiny connectors

Man, hate when e-mails don't auto-shorten. Thread was huge!

Don't think anyone has mentioned the obvious (excuse me if I missed it, it
is quite late) but why not drop some solder paste on the pads, chuck the
connector in there and throw some reflow heat onto it... hold it down with a
tool to be safe. Is there any reason why that wouldn't work? It's hard to
tell what's going on with the pictures because nothing was marked or
labeled. If you're going to be around HacDC, shoot me an e-mail and I'll
help you out.

Cheers,

-Q
