Two basic categories of particle type classes were operationally defined: "heavy metal" and "other inorganic." The former consisted of those classified as Pb type ([+ or -] Ca, and/or P), Sn type (containing predominantly Sn), Zn type (composed almost exclusively of Zn), SnZn type, Sb-containing type, SbPb type, and "other metal" particles (Cu-, Ni-, Cd-, or Mn-containing).

Abstract: A copper substrate was coated with SnZn lead-free solder (SnZn9 and SnZn8Bi3), and the following corrosion tests were performed: salt mist, gas corrosion and weathering.
Tin-zinc (SnZn) and tin-zinc-bismuth (SnZnBi) are still outsiders for reflow soldering for the foreseeable future.
