Abstract
An improved method for screen printing fine lines of conductive paste on a substrate wherein a mask having a desired pattern of line shaped openings is placed on the substrate, and conductive paste screened in the openings in the mask in contact with the substrate, and also as a thin layer over the top surface of the mask. The mask is removed from the substrate before the conductive paste in the openings dries, thereby leaving a fine pattern of paste lines with a uniform height on the substrate.
