DuPont: New Silver Conductor for Printed Electronics
Thin-line printing on a variety of substrates is possible with new functional inks.
Research Triangle Park, NC — DuPont Microcircuit Materials (MCM), a business unit of DuPont Electronics & Communications, 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.

According to the company, printed electronics manufacturers are looking for ways to do more with less material, and this new development is filling that critical need. The new product can reduce silver cost by providing higher conductivity with thinner prints of conductor traces. Some customer applications that require high current had previously required the conductivity achieved by a double print step. Now these applications can be enabled while saving the second print process step with a single print, which will still achieve the desired conductivity.

The new DuPont ink can be printed onto a variety of substrates, including Polyethylene Terephthalate (PET), Polyethylene-Naphthalate (PEN), DuPont Kapton® polyimide films, paper, and other materials. The composition is solvent-based and was designed to be screen printed in semiautomatic or high volume reel-to-reel applications.
