PRISM: Optimized for Semiconductor Packaging Applications
The PRISM-500 is a fully programmable X-Y-Z coating system for the precise application of photo-resists, polyimides, photoimagable soldermasks, conductive inks, silver paints and other materials. Available in batch configuration or with an in-line conveyor, the PRISM leverages USI's patented, nozzle-less ultrasonic spray technology that is industry-proven for a more accurate, thinner coating than conventional air atomizing nozzle or spin coating methods.
