摘要： When external electrodes of a multilayer ceramic capacitor are formed by performing direct plating on surfaces at which internal electrodes are exposed without forming paste electrode layers, bonding forces of plating layers are relatively weak, and in addition, when glass particles are included in the plating layers, blisters are often generated. To overcome these problems, a multilayer ceramic capacitor is formed by performing electrolytic plating using a plating bath including glass particles, electrolytic plating layers including glass particles dispersed therein are formed as the external electrodes.

摘要： A multilayer ceramic electronic component includes external terminal electrodes that are formed by depositing metal plating films on exposed portions of internal conductors embedded in a ceramic body, depositing a copper plating films that cover the metal plating films and make contact with the ceramic body around the metal plating films, and heat-treating the ceramic body to generate a copper liquid phase, an oxygen liquid phase, and a copper solid phase between the copper plating films and the ceramic body. The mixed phase including these phases forms a region at which a copper oxide is present in a discontinuous manner inside the copper plating film at least at the interfaces between the ceramic body and the copper plating films. The copper oxide securely attaches the copper plating films to the ceramic body and enhances the bonding force of the external terminal electrodes.

摘要： In a method for manufacturing a laminated ceramic electronic component, after a plating layer for an external terminal electrode is formed by applying copper plating to an end surface of a component main body at which respective ends of a plurality of internal electrodes primarily including nickel are exposed, when a heat treatment at a temperature of about 800° C. or more is applied in order to improve adhesion strength and resistance to moisture of the external terminal electrode, voids may occur in the plating layer. The step of applying a heat treatment at a temperature of about 800° C. or more to a component main body with plating layers formed thereon includes not only a step of maintaining a top temperature of about 1000° C. or more but also a step of maintaining a temperature of about 600° C. to 900° C. at least once before the step of maintaining the top temperature. These steps preliminarily diffuse copper included in the plating layers, which has a relatively high diffusion velocity, into the internal electrodes primarily including nickel, thereby reducing a difference in diffusion velocity between copper and nickel at the top temperature, which causes the occurrence of voids.
