RE: Why does solder have a lower melting point than Lead or Tin.
Solder alloys typically involve 2 or more of the following: Ag, Bi, Cu, In, Pb, Sn.
Present researches on solder alloys are directed toward 1) replacement of toxic Pb and 2) increased reliability (resistance toward thermal fatigue and the growth of Sn whiskers, etc.). A portion each June issue of JOM is devoted to lead-free solders, e.g.,
