Latest Patents

Ching K Chieng's latest patents include a method for applying a conductive trace pattern to a substrate. This innovative fabrication method utilizes an ink composition that is applied to a selected substrate through an ink delivery system. The ink contains an adhesive along with various additives, including solvents. The ink is delivered in a specific pattern, followed by the application of powdered metal that adheres to the adhesive. After removing excess powder, the substrate is heated to melt the powder, resulting in a pattern of conductive traces that correspond to the initial ink pattern. Another significant patent involves the formulation of new inks for thermal ink-jet printers. These inks replace a large percentage of the aqueous component with an organic liquid that can adhere to and penetrate plastic films, acting as a solvent for the dyestuff. The resulting printed ink is water-fast, smear-resistant, and substantially indelible.
