Preparation method for safety chip type multilayer ceramic capacitors

Abstract

The invention discloses a preparation method for safety chip type multilayer ceramic capacitors. Internal electrode patterns are printed in parallel on each ceramic dielectric film, a predetermined number of ceramic dielectric films are laminated in a way that the opposite internal electrode patterns of the neighboring ceramic dielectric films at the same position are laminated in a staggered manner, so that a laminated plate is formed, and the laminated plate is cut to obtain a safety chip type multilayer ceramic capacitor green body; and as the laminated plate is cut, the cut surface has the internal electrode patterns which appear at intervals, and the interior of the cut laminated plate comprises internal electrodes which are suspended relative to the surface of the cut laminated plate. As the interior of the safety chip type multilayer ceramic capacitor prepared by the preparation method for safety chip type multilayer ceramic capacitors has the suspended electrodes, the open circuit state of a circuit is guaranteed, the problem that short-circuiting can easily take place when the capacitor is cracked under stress is prevented, and the problem that personal safety is endangered by electric stock as the result of the short-circuiting of the capacitor is also prevented.

Description

technical field [0001] The invention relates to the field of capacitor preparation, in particular to a method for preparing a safety chip multilayer ceramic capacitor. Background technique [0002] Chip multilayer ceramic capacitors (Multi-layer Ceramic Capacitors, MLCC) are multilayer ceramic capacitors composed of alternating layers of ceramic dielectric and metal internal electrodes. The alternate and unconnected internal electrodes are respectively connected to the external electrodes at both ends to form a parallel structure of multiple capacitors. [0003] Conventional chip multilayer ceramic capacitors are prone to cracking when subjected to stress, and the capacitor will fail, which will easily cause a short circuit in the circuit where it is located, resulting in electric shock and endangering personal safety. Contents of the invention [0004] Based on this, it is necessary to provide a safety chip capacitor that avoids the above-mentioned problems in view of th...
