USI Advances Adoption of Package Level EMI Shielding with Advanced Silver Conformal Coating

Haverhill, MA – Haverhill, MA, USA, September 25, 2018 – Ultrasonic Systems, Inc. (USI), a leader in high performance coating application equipment, is announcing the sale of several of its PRISM ultra-Thin Coating Application Technology (tCAT) spray coating platforms for use in package level electromagnetic interference (EMI) shielding using advanced silver conformal coatings.

Since first announcing this capability, USI has shipped multiple systems to semiconductor manufacturers in China, Taiwan, and the United States to support manufacturing using advanced silver materials from major providers. Unlike sputtering-based coating equipment, this new process has proven to have excellent EMI shielding effectiveness (1-10 µm), improved design flexibility, and lower overall cost of operations and ownership.

“The use of silver coatings for package level EMI shielding has rapidly moved from the lab to the production floor,” said Stuart Erickson, President at USI. “Smartphones and other smart devices have increasingly-compact form factors that demand higher performing EMI shield effectiveness. Our PRISM systems with our tCAT technology have proven to outperform other coating systems when measured against our customer’s technical and business objectives.”

Key to the acceptance of these new silver EMI materials was the superior coating capabilities of USI’s core technology called tCAT. This proprietary nozzle-less ultra-Thin Coating Application Technology is used for thin, uniform application of a wide variety of coatings from pure solutions to high-solids suspensions and slurries. USI’s tCAT utilizes “nozzle-less” ultrasonic spray technology combined with a precision metering pump liquid delivery system, which is part of a coating system platform with a motion and positioning system for the spray head, and a transport system for the substrates to be coated.

Electromagnetic Interference (EMI) is a process by which disruptive electromagnetic energy is transmitted from one electronic device to another via radiated or conducted paths, or both. In electronic components, devices, and systems, EMI can adversely affect the performance of today’s faster, smaller, electronic devices that contain digital circuits. EMI shielding helps designers obtain the highest possible operating and processing speeds from the smallest possible physical package without performance-degrading interference.

USl’s PRISM-500 Selected for Precision Coating App at European Biomedical Company

Haverhill, MA – Haverhill, MA, USA, April 5, 2018 – Ultrasonic Systems, Inc. (USI) announced today the installation of its PRISM-500 high-speed, high performance spray coating system at a European-based medical company that sells instruments used to perform medical diagnostic tests. USI’s patented, nozzle-less tCAT ultra-Thin Coating Application Technology was chosen to apply an activation agent (coating) to the surface of a biomedical diagnostic instrument carrier that holds multiple test samples.

USI’s tCAT ultrasonic spray technology is a novel application method that deposits an ultra-thin, uniform and defect-free coating to the test substrates, which are about the size of a playing card and contain multiple test locations used for diagnostic testing.

With coating transfer efficiency of up to 99% and finished film thicknesses as low as the sub-micron range, the PRISM-500 handles high-precision applications. USI’s nozzle-less design delivers a much thinner and uniform coating layer than is possible with nozzle-based spray coating systems.

“Our systems provide a superior solution for a variety of medical applications ranging from implantable devices to diagnostic tools. Applied coatings include drug eluting coatings, reagents, protective coatings, and more,” said Stuart Erickson, President of USI. “We meet the real-world needs of medical device manufacturers.”

USI’s PRISM systems provide greater process control and uniformity than other spray technologies can deliver. The product line includes PRISM-400, PRISM-500, PRISM-800, and PRISM-1200 for larger format coating applications.
