Halide and Non-halide Contam. in Plating
Solution [Philippines]
+++
We have an MSA based plating solution. A chilled water is passed
through cooling coil to maintain the temperature of plating at
optimum during operation. At one instance, the fitting of chilled
water broke loose and the chilled water contaminated the plating
solution.
Question: We know that chilled water/hard water contains
chlorides, sodium etc... On what chloride level can we say that the
plating bath is still acceptable for use? Literatures have different
figures, but the bottomline is that chloride is a NO NO to
plating...but to what level?

You haven't given enough info to help. You've said that you are
plating in an MSA bath, but what are you plating, what is the
substrate, etc?

You forgot to say what kind of metal, plating chemistry and
substrates you are talking about.
