Ultrasonic Systems, Inc. (USI), the leading manufacturer of high-performance ultrasonic spray coating equipment for solar, fuel cell, medical, and semiconductor applications, has been awarded a patent for their CAT ILDS series of nozzle-less ultrasonic spray heads by the United States Patent and Trade Office. The CAT ILDS spray head is an integral part of USI’s versatile Prism spray coating machine, optimized for the thin, uniform application of a variety of low viscosity materials.

The CAT ILDS nozzle-less ultrasonic spray head features a coating pattern range of 3mm to 25mm, and is available in 35 kHz or 60 kHz frequencies, depending on the viscosity of the liquid. The CAT ILDS can handle a variety of coating liquids, including fuel cell coatings, conductive inks, fluxes, photoresists, dopants, and conformal coatings, as well as other proprietary liquids. All process parameters such as liquid flow rate, air pressure, the height and speed of the CAT ILDS head are set electronically for maximum control and flexibility.

"USI is honored to announce its newest patent for the CAT ILDS series of spray heads", said Stuart Erickson, President of Ultrasonic Systems. "Our engineering team is constantly improving our technology, especially regarding the spray heads, so our customers can benefit from the most accurate and efficient coating equipment available."
