One of the more interesting changes that I am seeing in processing of PCB's
these days, and I suspect strongly that it is due to mousebites, is a switch
away from air agitation in Copper plating to in-tank pump agitation. The
pumps are usually VERY powerful, and they do entrain small, and I do mean
small, amounts of air into the solution, but the level of agitation is, if
anything, even higher than air agitation, and the level of air entrainment
drops to virtually nil.
Something to consider strongly for your situation.
