Abstract
A solvent-free method for fabricating conductors is disclosed. A thick patterned layer up to 13 microns containing metal precursor and reducing agent precursor are initially deposited onto a substrate using laser printing technology. The deposited patterned precursor materials are then irradiated with a newly developed high energy intense pulsed light (IPL) system in order to transform the deposited materials to thick conductive metal patterns. The easy metallization of printed patterns makes this invention an especially effective method for massive production of flexible printed circuits.
