Must be the new math - 361 - 354 = 100. <Grin!> Or have I managed to
miss something?

Actually, silver bearing solder has a lower melting temperature than 63/37 tin/lead
solder...63/37 melts at 361 degrees...The silver bearing solder that McMaster-Carr sells
is listed at 354 degrees, almost 100 degrees cooler than 63/37, and is called "low
melting point " solder...It's composition is 62% tin, 35.75% lead, 2% silver, 0.25%
antimony, and it has a multi-flux core...It meets J-STD-006 federal specs, which is the
same as 63/37 and tells me it safe to use...It costs about $10 a pound more than 63/37
and seems ideal for SMT...
