Conductive line preparation on resin surfaces by laser micro-cladding conductive pastes

摘要

In this paper, a novel method named laser micro-cladding conductive pastes was used to fabricate silver conductive lines or patterns on resin surfaces directly. The effect of laser power, coating thickness, and the scanning rates on the conductive line widths was studied systematically, and the resistivity of conductive lines and its adhesion strength with the substrates were measured at different conductive silver particle content levels, based on which the composition and processes were optimized to obtain high quality conductive lines that was narrow, homogeneous with high conductivity and adhesion strength. Finally, the mechanism by laser micro-cladding conductive pastes was discussed.
