Some years ago when I was a Materials Engineer for Hewlett Packard,
solder was one of my categories.
The purpose of flux is to "reduce" (eat away) the oxide coating on the
copper so the solder can stick to it and also as a wetting agent to
reduce the surface tension of the molten solder and to pre
ok, thanks for that, the latest RS stuff says:
Crystal 400 60/40 Tin/Lead EN29453, S-Sn60Pb40E
the Elecraft HAGC mod instructions for SMD say
63/37 or 60/40 Sn/Pb-content rosin-core solder, 0.015" to 0.025"
diameter
so my S-Sn60Pb40E looks like thats the same alloy, not sure what the

Hi Dave,
Your 60/40 solder could possibly result in what are referred to as
"cold" or "disturbed" solder joints. If I were you I'd only use that stuff
