Abstract
A method for forming electrical traces on a substrate includes the steps of: providing a substrate; printing an ink pattern using an ink on the substrate, the ink including a aqueous medium containing silver ions and a heat sensitive reducing agent; heating the ink pattern to reduce silver ions into silver particles thereby forming an semi-finished traces; and forming a metal overcoat on the semi-finished traces by electroless plating thereby obtaining patterned electrical traces.
