If you do not get both pieces of metal hot enough to melt the solder you will end up with what is called a 'cold solder'. Sometimes you can tell by the fact that the joint will look hazy rather then nice and shiny. A cold solder can lead to high resistance and cause lots of problems including extra heat. I still have a v1 first batch running strong, but I have soldered many, many times.
I am sure many know this, but you heat the metal, then apply the solder to the metal, NOT the iron.

Yea.. I hear what you are saying.. I have been soldering crap longer than I was ever in school and in the service.
I'll reflow everything tomorrow.
