Ultrasonic Coating System to Be Highlighted at SEMICON West

Jun 10, 2013

Sono-Tek Corporation (OTC BB: SOTK), a global ultrasonic  technology company, will exhibit its ExactaCoat Ultrasonic Coating System in Booth #411 in the South Hall at the 2013 SEMICON West exhibition & conference, scheduled to take place July 9-11, 2013 at the Moscone Center in San Francisco, CA. The ExactaCoat is ideal for coating Photoresist onto MEMS and deep well topographies as well as other uniform coatings such as TCO layers, CNTs, polymers, AR, CIGS, and more.

The automated ultrasonic tabletop XYZ coating system has been designed for precision electronics manufacturing or R&D. The ExactaCoat is an economical system for coating thickness from 50nm to100 um.  Designed for precise spray processes where high precision, control, and uniformity is required, the system includes uniform and repeatable thin-film coverage of plus or minus two percent. Additionally, the system features complete process control with user-friendly Windows®-based software.

The programmable XYZ motion system offers a spray area of 14x14" with controllable drop size depending on nozzle frequency (25-180kHz). The integrated ultrasonic nozzles provide up to 80 percent reduction in material consumption, non-clogging performance, and precise, targeted spray patterns. Several liquid delivery options are available depending on the flow rate, and several spray shaping options are available, depending upon coating requirements.

Sono-Tek’s ultrasonic coating systems can be easily be scaled to higher volume production scale equipment. For more information about the ExactaCoat Ultrasonic Coating System, see Sono-Tek in Booth #411 in the South Hall at SEMICON West or visit

Sono-Tek is the world leader in the development and application of liquid ultrasonic atomization technology into nozzle systems and spraying and coating application systems. Compared to conventional pressure spraying methods, the company’s ultrasonic nozzles do not clog, reduce liquid usage, waste, and environmental impact while achieving much more precise, uniform, thin film coatings. Sono-Tek is continually developing new applications for its unique technology, replacing wasteful practices in a world that is growing ever more environmentally sensitive.
