Gene,
Unfortunately, I have occasionally seen "60/40" solder for
sale that, upon reading the SMALLER print, is 60Pb/40Sn.
I have never seen that. But of course, it might happen... We should be
aware though that anyone selling "60/40" solder that contains 60% lead
is a crook, because by long standing international standards the tin
content is ALWAYS given first! So a solder with 60% lead and 40% tin
MUST be labelled "40/60" and not "60/40".
That some hams don't know the difference between 40/60 and 60/40 solder
is another matter. It happened to me, when I was starting in
electronics, at age 12, and bought some 40/60 solder thinking it was the
same as 60/40.
