Profile: Sono-Tek is a supplier of ultrasonic spray technology products and related equipment. The non-clogging nature of our ultrasonic nozzles gives us significant advantages over other fluxing methods in precision selective fluxing of SMT circuit boards and components as well as fluxing through-hole and SMT circuit boards with stand-alone and inline systems. Some specific technology areas for solar cell manufacturing include solder bus fluxing of silicon solar cells, depositing suspensions for TCO layers in thin film solar cell manufacturing, phosphoric doping and spray pyrolysis applications. Fuel cell coatings for the production of PEMs include deposition of catalyst inks such as carbon black and other precious metal suspensions onto nafion membranes. Our ultrasonic technology offers uniform thin film nanocoatings that are highly durable and maximizes efficiency with minimal overspray of expensive inks. We offer modular spraying systems for use in coating moving webs of material for industrial applications such as continuous manufacturing float glass which requires non-clogging, reliable, uniform thin film coatings across a wide area. These systems have a significant impact on environmental manufacturing practices as well as dramatically reducing material usage. Our ultrasonic nozzles are used in nanotechnology applications such as spray drying, with unique benefits including deagglomeration of nanoparticles from aqueous solutions containing nanomaterials such as metal oxides and carbon nanotubes. Our systems are capable of producing a high yield of particles in the 150-300 nm range.
