Ruby makes all kinds of flux. http://www.imsspssales.com/page46.html They
type I used turned a water pipe green. It was intended for plumbing and
stained glass. They do make something for electronics but I have never used
it. Careful!

Many years ago we used a product called Ruby flux. With this stuff, you
could solder to anything, especially stainless (we used to use it for this
application). It does, for obvious reasons, need to get thoroughly cleaned
(water soluble) right away. All I know is that is was pink in color, don't
have any other information, though.

Subject: [TN] soldering to stainless
Here is my problem. One of them anyway. We have an assembly with a
stainless
steel pin that has a flex soldered to the end. Currently the pin is
nickel
plated. Due to some problem which has not been explained to me very
clearly, it
has been proposed to eliminate the nickel plate. My problem is
obvious. How do I
solder a little flex to the end of this stainless steel pin? This is
a high
dollar, high reliability assembly. ( Navy pilot wants this to work )
Any
suggestions or advice are welcome. It may be posssible to have the
pin plated
only on the area that gets soldered but I am looking at the worst
case because I
have been around long enough to know that somebody who does not have
to deal
with a problem can always make it harder on those who do.
Thanks in advance,
