DuPont Microcircuit Materials Introduces New Silver Conductor for PE

DuPont Microcircuit Materials (MCM) has introduced its latest screen printed silver conductor material for the printed electronics market. Utilizing proprietary technology and under typical processing conditions used for many printed electronic applications, DuPont 5064H silver conductor ink provides resistivity less than or equal to six milliohms per square per mil, making it among the most conductive and cost-effective screen printed silver conductor material on the market today. DuPont continues to expand its portfolio of functional inks and pastes for the growing printed electronics industry.

“Printed electronics manufacturers are looking for ways to do more with less material, and this new development is filling that critical need,” said Scott Gordon, market segment manager — DuPont Microcircuit Materials. “DuPont 5064H can reduce silver cost by providing higher conductivity with thinner prints of conductor traces. Some of our customers with applications requiring high current, who previously required the conductivity achieved by a double print step, are now able to save the second print process step with a single print of 5064H and still achieve the desired conductivity.”

DuPont 5064H can be printed onto a variety of substrates, including polyethylene terephthalate (PET), polyethylene-naphthalate (PEN), DuPont Kapton polyimide films, paper,and more. The composition is solvent-based and was designed to be screen printed in semiautomatic or high volume reel-to-reel applications.

This and more DuPont MCM products will be featured at this year’s Printed Electronics USA trade show, Nov. 30-Dec. 1, 2011, which is co-located with Photovoltaics USA 2011 in Santa Clara, CA. Also highlighted will be the new low temperature processing DuPont Solamet PV414 photovoltaic metallization paste, designed for rotary screen printing to enable high speed roll-to-roll processing of thin and flexible solar cells and modules.
