Here's a link to an article regarding foam mitigation techniques. It my be helpful. There are many causes of foam. Water alone does not foam. Flux, solubilized in to the water can produce foam. Defluxing additives contain defaming agents which should

I may be mistaken but I believe that the solvents have defoaming agents in them. I get less foam when I use the solvent than when I don't. If you dissolve the flux in water and agitate it I believe it will foam. I haven't had any over flow issues w

I wanted to bump this up. I am having the same problems. I cannot convince folks it is a solder mask issue and not our process issue, even though it shows up after wave and wash. I can heat the boards and even send them back through the wave preheate

we received assembled PCBs with spots that look like a bleach spots all over the PS and CS . The board house said that this is normal due to flux aqueous wash process. Can it cause problems (e.g. corrosion ) in the long run or cause issues when wor

What temperature were you running it at previously? We are having the same issue when using WS488 flux. Which flux was causing you issues?

Hi, Stephen. Thank you for the feedback. I want update my situation with the batch cleaner. I fallow all the suggestions that I received and I find out that; the water temperature was the reason. I raised to 150*F Regards Roberto
