The nozzle-type megasonic cleaning system uses specially designed nozzles to generate high-frequency sound waves and focus high-pressure, high-speed fluid onto the surface, which, combined with cleaning chemistry, efficiently removes particles and grease. It enables directional, efficient sound energy transmission, reducing energy loss by over 30% compared with tank systems, avoiding uneven sound fields and secondary contamination, and providing efficient, flexible ultra-clean solutions for semiconductors, precision optics, and medical devices.
