ABSTRACT:
The invention provides an article and process for producing electronic devices. More particularly the invention relates to an article and process for fabricating patterns of electrically conductive materials on non-electrically conductive substrates by laser ablation. Such an article and process find use in the production of RDIF devices, antennae, electrical circuits, microwave susceptors, contacts, leads, conductors, interactive displays, electrostatic shielding devices and the like. The process involves first providing an electrically conductive metal layer on an electrically non-conductive substrate. Then an electronic circuit is electrically connected to the electrically conductive metal layer. Thereafter a portion of the electrically conductive metal layer is ablated with infrared laser radiation to form a pattern of electrically conductive areas and electrically non-conductive areas on the substrate, wherein at least a portion of the electrically conductive areas are electrically connected to the electronic circuit.
