Abstract
Abstract A method of making single layer capacitors of relatively high capacitive value by applying a multiplicity of conductors to opposite sides of a first green ceramic sheet, applying additional green ceramic sheets on either side of the first sheet, laminating the sheets, scoring the lamination between the conductors, sintering the green ceramic into a monolithic structure, and snapping or breaking individual capacitors from the structure along the score lines.

Claim 1
Independent Claim
101 words
A METHOD OF MAKING SINGLE LAYER CAPACITORS IN MULTIPLE WHICH COMPRISES PROVIDING A FIRST THIN FLAT SHEET OF CERAMIC GREENWARE, DEFINING A MULTIPLICITY OF CONDUCTIVE PATTERNS ON EITHER SIDE THEREOF IN ALIGNMENT TO FORM A MULITIPLICITY OF OPPOSED INDIVIDUAL CAPACITORS, PROVIDING SECOND AND THIRD SHEETS, LAMINATING SAID SECOND AND THIRD SHEETS TO EITHER SIDE OF SAID FIRST SHEET, THEREAFTER SCORING SAID LAMINATION TO DEFINE INDIVIDUAL CAPACITORS BETWEEN BUT NOT EXTENDING TO SAID SCORE MARKS, FIRING SAID LAMINATIONS TO PRODUCE A CURED CERAMIC ASSEMBLY OF A MULTIPLICITY OF SINGLE LAYER CAPACITORS, AND THEREAFTER BREAKING CAPACITORS FROM SAID ASSEMBLY ALONG THE SCORE MARKS.
