Many organizations around the globe are actively involved in the research and development of printed displays, circuits, printed batteries, RFID tags and other printed electronics applications. The requirements for using printing techniques in the manufacturing of circuits are much more demanding than for conventional printing.There are many challenges that have to be overcome for successful printing and functioning of the printed circuits. These challenges are not only for the printing process and the substrates, but also for the functional inks used for printed electronics manufacturing.
This work focuses on gravure printing of conductive inks, more specifically silver, graphite and silver-graphite composite conductive inks. Silver inks provide much lower electrical resistance than the graphite inks. In order to achieve a wider range of resistivities, graphite inks are often mixed with silver. The effect of mixing silver and graphite inks at varying proportions on the conductivity of gravure printed resistors was studied. Results show a significant correlation between the ratio of conductive fillers and printing conditions. Electrical performance of printed conductive traces based on silver-graphite composites can be better predicted and controlled by using relationships established in this work.
