METHODS AND SYSTEMS FOR GEOMETRIC OPTIMIZATION OF MULTILAYER CERAMIC CAPACITORS

摘要

Methods and systems to improve a multilayer ceramic capacitor using additive manufacturing are disclosed. Conductive layer ends and dielectric layer edges of a multilayer ceramic capacitor may be modified to comprise a round shape, which may increase voltage limits by reducing electric field intensity that results from sharp corners. Further, the capacitor may comprise wave-like structures to increase surface area of a conductive layer and/or dielectric layer. The round shape of the conductive layer end may in-part reduce the need for a wide protective gap due to its dome-shape permitting the dielectric layer to be wider on top and bottom, and thinner at the center, e.g. concave, which provides strength support to the layers. The 3D Printing process permits the distance between the conductive layer end of the conductive layer to be much closer to the dielectric layer edge of the dielectric layer, such as below the standard 500 microns.

1. A multilayer ceramic capacitor, comprising:
a ceramic body; one or more dielectric layers alternately stacked with two or more conductive layers, wherein at least one conductive layer comprises a conductive layer end comprising at least one of a round shape, a bulbous shape, and a wavy shape; a pair of external termination disposed at opposite end portions of the body, and wherein the two or more conductive layers are alternately coupled to an external termination of the pair of external termination.
