Parametric Study for High-Frequency, High-Intensity Ultrasonics in Removal of Sub-Micron Particles

Vetrimurugan, J. Michael Goodson, and Terry Lim
Abstract—In this paper, we describe an experimental study undertaken to investigate ultrasonic and megasonic fields in the frequency range 25 kHz – 360 kHz, temperature range 30 οC – 70 οC and re-circulation range 0 – 10 GPM with respect to their surface cleaning and erosion potential. Measurements are performed using three different methods – LPC, cavitation intensity and aluminium foil test – to assess these mechanisms mainly for disk drive components. Conclusions are drawn regarding the nature of interactions between high-frequency, high-intensity ultrasonic fields and temperature. Recommendations are provided for optimal settings to maximize surface cleaning for variety of disk drive components.

Index Terms—Ultrasonic cleaning, megasonic cleaning, LPC, removal efficiency, cavitation intensity, erosion rate.
