Correlation of Dispense Characteristics of Conductive Inks to Substrate Temperature

Formation of conductors on a substrate can be achieved by dispensing conductive materials on its surface. The quality and reliability of these conductors depends upon the ink characteristics, substrate characteristics and the dispensing parameters.

In this study, two materials were dispensed on a substrate commonly used in the industry at various temperatures. Results of the effect of substrate temperature on the quality of conductors dispensed on it are presented. The line width, its cross section area and its resistance and resistivity were measured at increasing temperature of the substrate and correlated to the substrate temperature.
