Sorry, Joe, if my question was mistakable. I wanted to know your
application. Maybe I'd recommend not using a special solder alloy rather
than going the long way of aquiring it.
I give you an example: When fixing a 6.5 digit DMM (HP34401A) I wasn't
sure if I might use a special alloy to solder the pins of an input
relay. In the end I did not. Comparing this fixed unit to a second one
in several automated 24 hours tests with varying room temperatures,
there seem to be no measurable differences between the two. So in this
case it appears to be of no great importance using a special solder.
Enthough the thermoelectric voltages at these pins are not negligible
and therefore have to be considered, other effects obviously are of much
more effect. So, as I mentioned, using a special soldering alloy drops
in the priority list.
Now, that I'm curious, please let us know, what you are using the solder
for.

As I asked in my original message, I'm trying to find out where I can buy a
small quantity of rosin-core 10/90 (tin/lead) solder. I don't want to buy
it in bar form from China.

sorry, spelling mistake:
"What do you _want_ it for?"
Remember, those solder alloys are optimized for a specific alloy
combination only, e.g. Cu-Cu.

Hi Joe,
What are you looking for, Cadmium-Solder, or Sn10Pb90, which is
Stannum/Plumbum-only?
And what do you what it for? In (very high) precision applications there
are so many issues to consider that the solder doesn't appear to be at a
high priority...

Reading through the archives, I saw that there was some discussion about
a
safer alternative to cadmium-based solder. The low tin, high lead alloy
was
recommended as a good low-thermal EMF substitute. However, I did not see
any recommendations on where to buy some of this.
I just did some searching and all I come up with is bar solder, mostly
from
China. Where can I buy a small quantity of rosin-core 10/90 solder?
Mouser,
which is my preferred vendor certainly didn't list any. I would think
that
even 1/2 pound would last me a lifetime.
