CA 1335190

A method for producing a circuit board having conductive circuit elements with a specific resistivity of less that about 0.05 ohm-cm2 patterned on a non-conductive substrate comprises the steps of printing a UV-curable ink onto the non-conductive substrate in a desired circuit pattern, and effecting UV radiation cure of the UV-curable ink by exposing said UV-curable ink to a UV source having an output of from about 360 nm to 420 nm in a pulsing manner comprising from 5 to 8 one-half second exposure periods, each exposure period followed by a non-exposure period of from about 2 to 3 seconds.
