  • Patent number: 4347650
    Abstract: The present disclosure relates to a method of making a multi-layer ceramic capacitor and, in its more particular phases, to a capacitor having closely predictable tolerances. The method comprises the steps of providing or fabricating green ceramic sheets and imprinting or otherwise depositing on such sheets patterns of electrode material, the patterns each defining a continuous electrode area many times the anticipated area of the final capacitor. A multiplicity of layers of the ceramic and electrode are stacked and increments of the composite mass are cut therefrom in the direction perpendicular to the axis of elongation of the electrodes, which increments are thereafter fired, terminated and glazed or enveloped in an insulating coating whereby there are formed capacitors which are substantially marginless, i.e. do not include borders of ceramic material projecting beyond the electrode area.
