I�m using Zestron's Vigon sc 200 in our ultrasonic cleaner. It works great for cleaning our adhevises and pastes (RMA and no clean) from stencils and misprinted PCBs. We used to use a saponifier which did a terrible cleaning job and was a real pain t

Pete C Thank you for answer. Yes we have to remove solder flux so we need chemistry for no-clean flux residue. What kind of damage can i expact from ultrasonics device? you said damage IC and clock types?. We have all components in solid encapsulat

It was a resonant frequency that brought down the Narrows bridge. Memorex can shatter a wine glass with resonance. Ultrasonic washers use frequency to do what they do. If anything on the pcb has a length width or mass that resonates at the washers fr

Now you are putting your assembly to vibrate with frequency of 30-60kHz. What kind of flux/paste are you using? If it is NC there is no reason to clean. If it is water wash, you should consider a proper way of cleaning it according to your paste/flux

Hello Paul, Prior to 1980, I would say that your concerns were real regarding the resonant frequency. However, since then all major ultrasonic cleaner manufacturers use a "sweep" frequency technology. By "sweeping" or alternating the frequency bet
