Kenneth,
Okay you have me curious, so what else would one run through a
HASL solder pot, other than bare copper?
Franklin D Asbell
Julie,
You must be soldering bare
copper/OSP boards if your getting copper
contamination in your bath.
There is not much you can do about it but the
contamination will build up
quicker in small solder pots as opposed to the
larger (1000 lbs +)pots.
If
your not soldering copper boards then start looking for the person that
is
throwing pennys into the bath. (Yes, I have seen this happen) If
you
have any doubt about the solder your using then you should have it
analysed
by someone other than your vendor.

solder pot
TechNet,
We have sporadic problems with the
copper level rising in our solder pot.
We
reduce the temp and dross each
morning. Could you recommend a specific PM
program to keep our SnPb clean? We
believe per the certicates of analyses
that
our supplier gives us good
product. Any other reasons it might
rise?
Thanks,
Green
