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

Hi, colleagues! We only start using pb-free tehnology Our wave have foam fluxer What kind of flux would be best if we will use Sn100 solderbar What is your experience Best regards Peter

Indium Corp. has some, 3549-HF and 3590-T, both are OK for foaming. Most of the better performing newer fluxes require spray application for best performance. Alpha, Kester and others have wave fluxes too. http://www.indium.com/products/circuitboar

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 haven't seen a hydrometer used in years. Are you still foam fluxing? There used to be automatic units available, but with the advent of the spray fluxer, they may have dried up. If you are still foam fluxing with alcohol thinner, place ping pong
