METHOD FOR PRODUCING A HEATING SYSTEM ON A 3D PLASTIC PANE LIKE A 3D PLASTIC MOTOR VEHICLE PANE

摘要

A method for producing a heating system on a 3D plastic window, such as a car window. The heating system having an electric heat conductor structure with at least two bus bars and a grid line pattern with a plurality of grid lines. The method having: a step in which the two bus bars, made of a first electrically conductive paste are screen-printed onto the window by a displaceable squeegee; a step in which the grid line pattern is applied onto the window such that it respectively overlaps the two bus bars with at least one second electrically conductive paste which has a greater electrical resistance than the first electrically conductive paste, and a final step in which the two bus bars and the grid lines overlapping these bus bars are at the respective overlapping points electrically connected into the electric heat conductor structure by means of electrical connectors.
