ABSTRACT:
A group of monolithic ceramic capacitors are made by repeatedly passing a substrate under a falling curtain of a ceramic slurry, drying each layer and screen printing an electroding ink pattern on successive of the dried ceramic layers to provide a green cake containing buried electrode patterns. The cake is diced using a razor blade. It is then removed from the supporting substrate and flooded with liquid nitrogen. The chilled cake is then mechanically stressed to provide near perfectly separated green bodies along the cutting planes.
