Onda to Present Acoustic Measurements of 3 MHz Transducers for Mask Cleaning

September 12-14, 2016 – Onda is pleased to collaborate with Honda Electronics, SUSS MicroTec, and the University of Arizona to present a study which evaluates the acoustic performance for two 3 MHz transducers used for photomask megasonic cleaning.

The poster is titled:

Acoustic Characterization of Two Megasonic Devices for Photomask Cleaning

Abstract:

New methods to measure stable and transient cavitation were applied to two megasonic cleaning devices. One is a novel design consisting of a transducer coupled to a tilted, truncated quartz cone with a 4 x 6 cm elliptical flat surface, coupled with the substrate by cleaning fluid infused through the cone. The second device is a spot shower that uses a smooth jet of cleaning fluid to convey the sound. Results of the measurements, acoustic maps and schlieren imaging are used to explain the cleaning performance of each device.

Onda’s Cavitation Meter Wins Best Monitoring/Instrumentation Product

May 16, 2016 – Onda is pleased to announce that the MCT-2000 Cavitation Meter has been voted the Best Monitoring/Instrumentation Product in Controlled Environments’ 2016 Readers’ Choice Awards.

This validates the long-standing need for a measurement solution to quantify the acoustic cavitation useful for various applications, such as ultrasonic cleaning and sonoprocessing. The MCT-2000 measures the fundamental frequency and pressures from the direct field, stable cavitation, and transient cavitation in SI units (i.e., Hz and Pa).

This announcement appeared in the May/June 2016 issue of Controlled Environments Magazine, as well as in the digital edition HERE.
