Dave is absolutely right! A question is there free standing DI water left on Parts after wash and rinse, if so this can definetly exacerbate the problem. You can try to remove excess DI water by using an IONIZER air source to blow off any water. S

Good Morning, I'm a relatively new engineer, and i've been experiencing a lot of anomalies when it comes to our inline wash. We have an Austin American Hydrojet, and no matter how many times i clean the tank, it still foams like crazy! its been happe

We're a CM doing low volume/high mix and are considering buying from one of the two big names, TR** or Sp*******/El*********. We need saponified wash for some of our no-clean over wave; the great majority is OA from our SMT lines. Any thoughts?

We had a similar problem with foam in our inline cleaner (TD). The problem were the solder paste flux residues. Boards went straight from SMT to Wave process and then washed. Anyway we changed the solder paste and problem solved. Are you using saponi

Kevin, Hot DI water will leach ions form stainless steel over time � much like an acid effect on metal. If you have ever seen a Steam Age Chamber after about 6-months use, you will know what I mean. DI water is �hungry� for ions and it will take th

Dunno, but if I had to guess, your DI is corroding the stainless. But then again, some saponifier concentrations can be overly caustic

Bill: I'm with you on the first thing that you said about DI water, but in the second paragraph, how do you reckon the saponifier affects the DI water?

Ok....this is the last time asking this question. Does anyone know how to clean the dull residue of the inside of a stainless steel batch cleaner. The system has always been DI based and run with a saponifier. I am not sure what the redusue is or

Dave, The saponifier (or any additive) will supply free ions and contaminate the DI water. If no contamination is introduced (very difficult) or if fresh hot DI water is constantly added as in a steam age chamber, the DI water will begin to obtain

You have a lot to think about! What does the flux manufacturer recommend as far as specifics like water temp or pressure? Do they recommend high temp di-water a detergent or saponifier? Do you currently have a cleaning machine, batch cleaner or inl
