Thick film inking system where circuit patterns are written by ink feed through an orifice of a writing pen. Line cross-section is controlled by synchronous positive displacement pumping of ink through the orifice with the motion of the substrate with respect to the pen. A dynamic pen control system

Thick film inking system where circuit patterns are written by ink feed through an orifice of a writing pen. Line cross-section is controlled by synchronous positive displacement pumping of ink through the orifice with the motion of the substrate with respect to the pen. A dynamic pen control system provides spring and mass compensation and maintains positive, prescribed pen force on the extruding ink thereby maintaining the desired thickness to width ratio of the lines.

For use in producing patterns on a substrate with viscous material and with the aid of flexurally supported member having an orifice, a system comprising means for moving said substrate with respect to said member, means for controllably feeding said viscous material through said orifice at a volume

For use in producing patterns on a substrate with viscous material and with the aid of flexurally supported member having an orifice, a system comprising means for moving said substrate with respect to said member, means for controllably feeding said viscous material through said orifice at a volume rate synchronous with the rate of relative movement of said member and substrate, and means coupled to said member and responsive to the viscous forces on the viscous material flowing from said orifice upon said substrate for allowing said viscous forces to determine the vertical displacement of said member to maintain a constant thickness of line of said material in said pattern for a given cross-sectional area of said line.
