The principle of ultrasonic PCB circuit boards is mainly to generate small bubbles through ultrasonic vibration. These bubbles adsorb pollutants on the surface of the object and continuously rupture under the high-frequency vibration of ultrasound, releasing energy to clean the pollutants off the surface of the object. This process can effectively remove pollutants such as dirt, grease, dust, and bacteria from the surface of objects, achieving the goal of cleaning and purification.
