Here's a pretty good thread from the fine SMTnet Archives on water wash foaming http://www.smtnet.com/Forums/Index.cfm?CFApp=1&Message_ID=50623

We just stepped into the inline wash world with a techical devices new clean galaxy plus. We are noticing a significant amount of foaming when washing our boards after selective solder. One theory is that the water soluble flux used is not being cu

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

We used to have a Nuclean 324 that was running closed loop with a DI water recirc system. We also had problems with foaming that was solved with a relatively simple fix. We bypassed the final rinse solenoid so that it was always running. This allo

The presence of agitation at an air / solution interface and a foaming agent causes foaming. Most water soluble fluxes contain surficants. Surficants are foaming agents. First, it's likely this foaming is caused by poor control of the temperature of

I had the same situation at a facility a few years ago. We moved our wash from one building to another and it was fine for months and then we had the foaming issue similar to yours. We tried everything from adding anti foam agents to even having th

Hi all, we have a Speedline Technologies ELEOCTROVERT/Aquastorm 200. In January we stared supplying it with pre-filterd to the DI cabinet next to machine so our large media would last longer. All was fine for about 4 months and then we started gett

I relate to your problem. We face this issue sometimes. It's mostly flux from SMT, TH process or rework boards. To avoid foam in our Washer, we soak the boards in hot water for 10-15 min before running it through the washer. Or you can spray the boar

We have a batch washer. When it was being installed I noticed their was some foam when testing empty. We had already ran a load previously. I asked the installer and he said that it takes very little for there to be foam.
