Topic: Solder: The US Military does not allow lead-free. The only reason we have lead-free is that old electronics fill the land-fill. Lead-free does not solder as well as lead. A special solder is used. If you are hand-soldering, try to not buy lead-free parts.

Topic: Solder iron: PCB's are made by gluing a sheet of 1 to 4 oz. copper sheet to an epoxy sheet. So your copper runs on your delivered PCB are glued on. Therfor you should use an iron temperature controlled at 700 deg. Don't hold the iron on the joint longer than needed, and don't PUSH sideways on the joint. Weller irons on ebay are the best, but for some reason they demand almost a "NEW" price! You can buy a "scope cheaper!
