Hi ya'll!

Just brainstorming a bit...when you have two different flux processes, what
do ya'll think makes most sense, have two different and separate cleaning
systems, or have one system that will cover both?

Precisely; we do both RMA and water soluble, and have two different cleaners
here... an Electrovert MCS-1000 for our RMA boards (which is basically a
fancy batch cleaner) , and a old Hollis Polyclean for our water soluble stuff.

I'm thinking that if we had the type of cleaner that would cover all the
different types of residues would be more cost effective than having two
separate cleaners. Sure, there would be saponification used (or some other
type of process to clean RMA residues that wouldn't be necessary when
cleaning water soluble flux residues) but still, wouldn't that make more
sense than trying to support two separate cleaners?

Does anybody else do this? Do any of ya'll use one cleaner that does it all?
Is it cost effective? I know it depends on the percentage of boards that are
RMA vs. water soluble...I would estimate our percentages are about
50/50...with the percentages increasing towards water soluble...don't think
that we'll ever consider no-clean anytime in the near future, it's just the
nature of our business...

As usual, thanks ya'll!
