You should check the archives, there has been much written on this subject in the past. Asking about the correct chemistry is wise. It never ceases to amaze me how many people think ultrasonics will work without the proper chemistry. Without the rig

I've worked at several companies that have used Smart Sonic ultrasonic cleaners. About a year ago, we purchased the Smart Sonic 1550 and Enviroguard. The Enviroguard produces DI water for rinsing and also handles the solder waste. Also, Smart Sonic h

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
