Abstract
Abstract Apparatus and process for directly printing an electrical circuit component onto a substrate includes structure and steps for providing a printing station, and for transporting the substrate to the printing station. Structure and steps are provided for printing, at the printing station, an electrical circuit component on the substrate using an electrically-conductive liquid. Preferably, the printed electrical circuit component is capable of performing its circuit function directly after printing, without the need for post-printing process steps such as etching, catalytic ink activation, electroless bath, etc.
