NovaCentrix Awarded U.S. PatentNovember 9, 2010
The technology covers the use of flash lamps to sinter metal-based inks and materials on low-temperature substrates, which is critical for the advancement of new products in photovoltaics, displays, RFID tags, sensors, batteries, capacitors, and smart packaging.
AUSTIN, TX /PRNewswire/ -- NovaCentrix, a leader in printed electronics manufacturing technologies, announced that U.S. Patent 7,820,097, entitled "Electrical, Plating and Catalytic Uses of Metal Nanomaterial Compositions," has been issued by the U.S. Patent and Trademark Office.
NovaCentrix's patent covers in part the use of flash lamps to sinter metal-based inks and materials on low-temperature substrates, such as paper and plastic, and includes high-speed and roll-to-roll processing. The process is critical to the advancement of innovative new products in photovoltaics, displays, RFID, sensors, batteries, capacitors, and smart packaging. As industry recognition, NovaCentrix received an R&D100 award for the development of this technology in 2009, as well as recognition by industry analyst group IDTechEx in 2008.
"One of the most exciting aspects of this technology is its scalability and economy. Inexpensive flexible substrates can now be used. Furthermore, processing can be performed at hundreds of feet per minute in a roll-to-roll environment," said Dr. Kurt Schroder, Chief Scientist and lead patent author. "In addition to processing silver, gold, and nickel used in conductive inks, the high-speed process can sinter easily oxidized particles, such as copper, in an ambient air environment, thus eliminating the need for a reduction furnace or inert atmosphere. The room-temperature process enables truly inexpensive conductive traces for printed electronics."
"Our patent validates and sustains NovaCentrix's position as a lead innovator in commercialized printed electronics technologies, including our PulseForge tools that apply Photonic Curing processing," said Charles Munson, CEO and President of NovaCentrix. "Our customers may use licensed PulseForge tools in their manufacturing processes without infringing this valuable patent."
PulseForge tools use the Photonic Curing process to heat thin films on low-temperature substrates, using novel flash lamp and power supply technology to deliver continuously adjustable, megawatt-intensity, microsecond-resolution pulses of broad-spectrum light. Unlike traditional oven technologies, the transient nature of the patented process heats thin films to a high temperature on low-temperature substrates, such as polymers, without causing damage. By adjusting the pulse attributes, using the touch-screen interface, temperature profiles in the film and substrate can be closely controlled and optimized for drying, sintering, annealing, and modulating chemical reactions in thin films to achieve high-performance properties at high-speed roll-to-roll photosintering processing rates.
NovaCentrix, based in Austin, TX, is a leader in printed electronics manufacturing technologies. The company's PulseForge tools sinter functional inks in milliseconds on low-temperature, flexible substrates, such as paper and plastic. NovaCentrix's tools process a wide array of metal-based conductive inks, as well as nonmetallic and semiconductor inks. NovaCentrix also offers high-performance, economical Metalon conductive inks, which work optimally with PulseForge tools.
