Sono-Tek Corporation Common Stock
stock NASDAQ

founded in 1975 by dr. harvey berger, inventor of the ultrasonic nozzle, sono-tek designs and manufactures precision ultrasonic spray nozzle systems used for thin film coating, spray drying, moisturizing, web coating, fine line and selective coating applications. ultrasonic coating systems are used in energy (fuel cell and solar cell), electronics (pcb fluxing), semiconductor (photoresist coatings), medical device coatings (implantable stents, balloon catheters, blood collection tubes, medical textiles and diagnostic device coatings), glass manufacturing, textiles, industrial, food, and nanotechnology coating applications. our ultrasonic nozzle systems operate by converting high frequency sound waves into mechanical vibrations to create nano to micron think coatings with very high uniformity and excellent transfer efficiency, minimizing overspray of expensive chemistries. the droplets produced by ultrasonic atomization are mathematically defined according to the nozzle's operating fr
