Abstract

The invention relates to a miniaturized high-reliability patch type safety ceramic capacitor and a processing method thereof. Ceramic capacitance powders prepared by using BaTiO<3>, SrTiO<3>, Bi<2>O<3>, Nb<2>O<5>, ZnO and MnO<2> raw materials are subjected to compression molding, calcinations and sintering to prepare fully symmetrical ceramic edge-retaining-free copper electrode chip prepared by utilizing a chemical deposition method or a plasma vacuum sputtering method. The miniaturized patch type surface mount ceramic safety container is achieved through adoption of overmolding warping and opening package of the leading-out end material. The advantage is that voltage withstand performance of the product is improved.
