Five Star Technologies announced that it will introduce ElectroSperse P-series silver-based conductor pastes at Display Week 2008 in Los Angeles on May 18-23. The new pastes are designed for use on low temperature plastic substrates typically found in such applications as display electrodes, touch screen sensors, heaters, RFID antenna, biosensors and membrane switches. ElectroSperse silver conductor pastes are rheologically stable, easy-to-process materials, designed for screen printing of electrodes and conductive traces on glass or other high-temperature substrates.
All ElectroSperse conductive pastes are characterized by exceptional fineness of grind and particle size uniformity, resulting in ease of processing and the ability to print fine features. ElectroSperse pastes also provide excellent adhesion to ITO or F-doped tin oxide-coated glass. A range of conductivity levels are available. The product line includes lead-free grades and grades designed for low-temperature processing. The initial P-series products are targeted for use in touch screen sensors, combining high productivity and ease of use with excellent conductivity and exceptional printability. The new pastes demonstrate excellent adhesion to a variety of flexible media, including ITO-coated polyester.
Like all pastes in the ElectroSperse line, the P-series products contain a highly uniform dispersion of silver with a tightly controlled particle size distribution in the low to sub-micron range. The ElectroSperse line also includes D-series silver-based cermet pastes, designed for firing onto glass and other high temperature substrates. D-series pastes are available in both leaded and lead-free versions and offer a unique combination of high conductivity, fine line printing, strong adhesion to coated-glass substrates.
Such uniformity enables customers to directly print features as small as 50 um with much greater precision and consistency than conventional pastes, eliminating the need for costly subtractive processes. Initial grades are intended for screen printing applications, but Five Star will soon introduce a series of products with controlled rheology to match a variety of printing processes.
Specific grades are available with firing temperatures as low as 380C, a temperature that often lends itself to significantly greater overall product stability. D-series pastes are ideal for printed interconnects and linearization patterns in capacitive and 5-wire resistive touch screen sensors.
Five Star employs its Particle Management Technology in the form of two basic platforms: a bottom-up synthesis method and a top-down dispersion processing approach. Combining Five Star’s unique, patented hydrodynamic cavitation process with innovative dispersion chemistries, these platforms allow the creation of a broad spectrum of advanced materials, dispersions, and formulations.
Kenwood has created prototype terrestrial DTV receivers based on the MPH in-band mobile DTV system, developed by Harris Corporation, LG Electronics and LG's U.S. R&D subsidiary, Zenith. Prototype in-car Kenwood MPH receivers - designed to bring terrestrial broadcast digital TV to consumers on the go, particularly those in fast-moving vehicles - will be demonstrated publicly for the first time at the 2008 International CES in January at the Kenwood booth N1001, Las Vegas Convention Center, North Hall.
