Hi, Maybe Yes� Maybe No� Actually, it most likely is acceptable to clean assembled boards in an ultrasonic cleaning system (40 kHz). There are some concerns in some circles about possible damage to wire bonds in components. There have been publi

Eric, The Kolb RB6D (and the RB5D) are not ultrasonic cleaners. They are high pressure spray cleaners. I would not recommend high pressure spray cleaners for misprinted assemblies with previously placed components (unless you don�t mind solder pas

There are a few good de-fluxing chemicals and many more �not-so-good� de-fluxing chemicals. As a manufacturer of cleaning equipment, it is imperative that our customers use a de-fluxing chemical that: #1: Removes flux #2: Is environmentally safe

Never use a water softener for defluxing. They add sodium to the water which is bad for boards. The white residue may be flux. If that's the case, either the dishwasher is not powerful enough or the wash water is not hot enough. Another possibili

Thank you for your replies. We use No-Clean Paste and some customers do not want any residue left around solder joint even so, so little. They want the residue washed completely. If we use water-soluble flux, we still need to wash, anyway. Their conc

This is a No-Clean solder paste, therefore, it's intended not to be cleaned. If you need your assemblies to be cleaned post assembly, I would highly recommend a water soluble solder paste. It will provide much better looking boards in the long run.
