In the past, I have sent back old solder paste to our bar solder supplier with
our dross. I got rid of old paste, didn't have to worry about scrapping
hazardous materials and they paid us for the "scrap" metal.
Just a thought.

Hi Steve -
Well, your wave solder pot will get pretty messy, definitely smell
bad/different for a period of time and you will generate quite a bit
of excess dross but I believe that as long as the solder alloy
originally met the ANSIJ-STD-006 specification requirements you won't
introduce any metallic type contamination that would cause you solder
joint reliability concerns. Have fun(??), wear a mask, and let us know
what happens.

Good day all!
This might seem like a pretty dumb question, but I was wondering if
there's
anything wrong with putting old solder paste in yer' wave solder pot? I was
feeling bored the other day, so I cleaned out our solder paste 'fridge, and
I've
got some jars of a bunch of different samples of no-cleans and water solubles
that were played around with in the past, and I just want to get rid of them
before an operator grabs one and uses it. They're all the same alloy (63/37)
but
there are different flux types. We're in a water soluble process now, and we
don't build missile guidance systems, just class-II stuff.
I wouldn't think it would hurt anything, but I don't wanna' do it if
there's
something I'm not thinking about and I wind-up contaminating the pot
somehow...
(BOY, the operations boss would have my "keester"!!!)
Any problems with doing that? I mean with adding old paste to the solder
pot? NOT with kicking my keester if I contaminated the solder pot...heck, I
would kick my OWN keester if I did that...heh,heh...
