Doug, See appendix B-2 of IPC J-STD-006 rev A, Requirements for Electronic Grade Solder Alloys and Fluxed and Non-Fluxed Solid Solders for Electronic Soldering Applications. There are good discussions as to the whys are wherefores in the Soldering books by Manko or Wassink. Both are highly recommended.

Percentages of the following elements would be useful: - Tin, lead, antimony, copper, zinc, iron, nickel, bismuth, cadmium, Silver, gold, arsenic, aluminium etc. We are using 63 / 37 bar solder into the machine. Also any mil-spec equivalents would be useful.
