A Note From The President

"From electronics assembly and fuel cell applications to semiconductor packaging and wafer processes the demand for a precise, uniform coating continues to expand. USI's patented ultrasonic technology meets these requirements for uniform coating thickness and reapeatability. The Prism system continues to evolve as a coating solution for many markets, applying a precise coating for a wide range of materials."

Stuart Erickson, President, Ultrasonic Systems, Inc.

USI's Curing Module offers
fast and safe topside curing of conformal coatings, and other UV curable materials. The UV curing system utilizes a modular design to deliver consistent curing of various width substrates up to 18" wide. Learn more...
Ultrasonic Systems, Inc.

Ultrasonic Systems, Inc. manufactures high performance spray coating equipment based on patented ultrasonic spray coating technology. Products include the PRISM Ultra-Coat Spray Coating System platform and a line of spray fluxing systems for the wave soldering process.

All USI systems feature patented nozzle-free ultrasonic technology which delivers a thinner, more uniform coating application than conventional spray nozzles, film coaters and jetters.

Electronics Assembly - Selective application of conformal coatings to printed circ uit boards.

Fuel Cell  - Precision application of low viscosity solutions and suspensions including carbon, platinum, ceramic and other proprietary materials.

Semiconductor Wafer - Precise deposition of photo resist, flux and conductive inks to wafers.

Semiconductor Packaging  -  Very thin film deposition of flux on BGA, microBGA, Flip Chip and Chip Scale Packaging.

Medical - Uniform application of low viscosity drug infused polymers and other coatings.

Prism Selective Coating Systems

The Prism Ultra-Coat is a line of programmable coating systems designed for the application of a wide variety of conformal coatings, semiconductor coatings, fuel cell coatings, medical coatings and solar cell coatings. The Prism employs a precision X-Y-Z-Rotate positioning system for the coating heads and is easily programmed with a Windows XP based graphical user interface.

Applications Lab Available for Trials
Conduct Your Coating Trial at USI's Lab 
 
Since many applications are proprietary and protected by non-disclosure agreements, the best way to see what USI's technology can do for you is to send your substrate and coating material to us for a trial. We will coat your substrate using our technology and return it to you with a video of the process. For details contact our applications lab at sales@ultraspray.com.

Prism Semiconductor Coating System

USI manufactures a high performance line of semiconductor coating systems based on patented ultrasonic technology.   The Prism Ultra-Coat is a line of programmable semiconductor coating systems designed for the deposition of very thin layers, flux, photo resist and conductive inks to wafers.  The Prism is ideal for spray coating wafers with micro-vias and non-traditional wafer designs.

Ultra-Spray Technology

All Prism Systems feature USI's patented Ultra-Spray  technology, which is industry proven and delivers a more precise spray coating application than conventional spray, spin coating, dispensing and other coating technologies.  Ultra-Spray coating heads employ ultrasonic energy to form a spray and low pressure directed air streams to shape and focus the pattern.

Lead-Free Wave Soldering Case Study:
Measuring Through-Hole Penetration

Lead-free solder alloys do not "spread out" and fill the plated-through holes of circuit boards as well as lead bearing alloys. As the industry moves toward lead-free soldering, applications are more dependent upon good flux chemistry and a robust fluxing system able to deliver flux into all plated-through holes of a circuit board.

USI and a leading EMS company conducted a recent Case Study  to measure the ability of USI's Optima Fluxing System to achieve complete flux through-hole penetration on extremely wide and thick circuit boards for lead-free assembly.
