......motion control platform with advanced material handling capabilities. The ultrasonic spray head uses ultrasonic energy to break the liquid into small drops to form the spray however the liquid does not pass through the device. Liquid is applied externally to a solid surface, which is vibrating at an ultrasonic frequency (>20kHz). Directed air streams are used to expand or focus the ultrasonically produced spray, providing a rectangular, uniform spray pattern. The liquid flow and airflow to the spray head are electronically controlled, providing complete control of the spray pattern shape and velocity. The coating system incorporates advanced liquid delivery systems to ensure that the coating liquid properties remain consistent during the coating process. The “nozzle-less” ultrasonic spray technology is widely used for applying various coatings in the electronic assembly industry. This paper considers a particular advancement in thin film application of fuel cell coatings using the “nozzle-less” ultrasonic spray head known as ultraspray technology with the integrated fluid delivery applicator and X-Y-Z-q-Æ motion control platform……continue
