An exemplary method for forming electrical traces on a substrate includes flowing steps. Firstly, a circuit pattern is formed on the substrate by printing a silver ions-containing ink. The ink comprises an aqueous carrier medium, and a silver halide emulsion soluble in the aqueous carrier medium. Secondly, an irradiation ray irradiates the circuit pattern to reduce the silver ions into silver to form a silver particle circuit pattern comprised of silver particles. Thirdly, a metal overcoat layer is electroless-plated on the silver particle circuit pattern thereby obtaining electrical traces.
