Ultrasonic cleaning Pot uses cavitation bubbles induced by high frequency pressure (sound) waves to agitate a liquid. The agitation produces high forces on contaminants adhering to PCBs. This process ensures contaminants like dust, dirt, oil, pigments, rust, grease, algae, fungus, bacteria, lime scale, polishing compounds, flux agents, fingerprints, are removed completely. To perform this activity we use multiple water based and other cleaning solvents like Acetone, IPA and MCS2.
