Liquid-borne acoustic energy in the frequency range from 350kHz to approximately 5MHz is becoming increasingly useful in a number of cleaning applications that require processing of extremely delicate parts and assemblies to remove particles ranging from a few microns down to a fraction of a micron in size. This ‘megasonic’ energy varies from the traditional ‘ultrasonic’ energy in that the frequency of operation is more than an order of magnitude higher than that of a conventional ultrasonic system. New generator technology makes it possible to operate ultrasonic transducers efficiently at more than one megasonic frequency, thereby extending their process
effectiveness.
