Hi Dave, It may be. DI water alone will not build up residue. It can attack the finish of electro-polished (mirrored) stainless steel though. I have seen a white / chalky buildup on poly inline cleaners, usually isolated in the wash section. The

Hi Dave, To close-loop or not to close-loop, that is the question� I can not speak for all machines, but in our case, close-loop systems are actually less costly to operate than open-loop systems (we make both). First, determine the volume of wate

Your question may be answered in two parts. First, if you are using a water soluble (OA) paste, then water is an excellent �solvent�. Water, in one way or another, is used to clean all fluxes and pastes from PCB�s. In some cases, a chemical is add

Dreamy, Adding chemistry to the wash section in a cleaner does have its advantages. It reduces the surface tension of the liquid and will remove contaminates such as fingerprints. It does however complicate the process in respect to water treatment

Most batch cleaners are "dishwashers" with stainless steel pipes and cabinets. Heated DI water is a good thing. Are you cleaning Watersolubles or no-cleans? You will need some chemistries for the No-Clean and the W.S. will eventually eat through al

"The fluid sometimes heats up to 105 deg F." Not sure what you mean here...is it set at 105 but rarely gets there, or is your temperature dependant upon another process to heat it up? Also, what temp is your rinse water? We used to use a U/S clean

Greetings All, Anybody out there experiencing white residues after cleaning? We currently use a batch cleaner to clean water soluble fluxes. this cleaner makes its own DI water by means of carbon and resin tanks. After cleaning there are residues

Hey there Dave! We used to use a batch cleaner when we used water-clean paste. It was similar to a dishwasher, except that it had a digital menu for entering the number of wash cycles, water temp., amount of saponifier (we just used DI water),

We have a need to clean boards. Can we use a regular dishwasher if we feed it with DI water thru a water heater? What kind of issues can come up with doing it this way as opposed to an industrial type batch cleaner? Any thoughts or comment would be a
