Hi Denis - Take a look at publication 656 Solder Alloy Data: Mechanical properties of solders and soldered joints by the International Tin Research Institute- it is a good apples-to-apples of Sn62 vs. Sn60 (sorry, no Sn63). One word of caution - comparison of solder alloy properties needs to take into account the use environment, stress/strain conditions, solder joint design, test method, etc - a simple solder tensile strength comparison would be misleading. There are many reports of the "improved" fatigue/creep properties of the Sn62 alloy over either Sn60 or Sn63 - I have found that all three alloys have equal properties in the use and design environments I deal with (and I recommend that we buy the most cost effect choice). Good Luck.

Does anyone know of a good publication I can refer him to?
