Fine Silver Conductor Trial Kit from DKN
Fine-line traces produced with new screen printing process.
Haverhill, MA — DKN Research is now offering a Fine Silver Conductor Trial Kit (capable of producing fine lines down to 80 microns) to companies interested in producing high density thick film circuits. The Trial Kit provides a low-cost practical solution for companies to experiment and overcome challenges with fine polymer thick film circuits and functional printable & flexible electronics.

The company has developed a broad range of technologies linked to advanced thick film circuits to target printable and flexible electronics.

Technical advances with ink materials and printing equipment have trickled down, and the wiring capabilities from the new thick film circuits are closer to traditional etched copper circuits. DKN has been developing a series of Advanced Screen-Printing Technologies and can build functional thick film circuits by partnering with equipment and material manufacturers. This new technology can result in fine silver traces down to 30µ lines and spaces for double and multilayer circuits with 80µ via holes. The conductivity is one order higher than traditional thick film circuits.

The conductor traces are available for soldering, unlike traditional polymer thick film circuits where soldering is impossible. In addition, this technology makes it possible to build embedded passive components and EL-based optical components on flexible substrates. It makes possible to build new electronic devices such as high-density touch panel switches, functional sensor modules, large size signboards, and flexible displays. The technology is also beneficial to build additional fine conductive traces on other circuit devices including multi-layer rigid boards, flexible circuits, ceramic circuits and monolithic IC chips.

The technology does not require a large investment in manufacturing equipment, and provides incredible capabilities for traditional printed circuit board manufacturers and screen-printing shops. The trial kit includes 100 grams of special silver ink, flexible film substrates with special treatments, a processing manual, MSDS (material safety data sheet) and examples of finished flexible circuits.
