Hi Ron,
First, I hope to get onto the golf course tomorrow if I get home from APEX.
Second, when you combine different metals, the Liquidus, that is the
temperature above which the whole mixture is liquidous, as well as
theSolidus, that is the temperature below which the whole mixture is solid,
can either go up or down depending on the metals and their percentages.
That is part of the problem in the search for a suitable 'lead-free'
solder--not that I think we need 'lead-free'--since all the options are
environmentally less friendly than Pb.
