摘要： In a method of forming an external electrode by growing plated depositions on exposed ends of a plurality of internal electrodes in a component main body, the component main body is polished to increase exposure of the internal electrodes. To prevent decreased external electrode fixing strength, a radius of curvature is reduced to about 0.01 mm or less for an R chamfered section formed in a ridge section of the component main body during polishing by ion milling, and exposed ends of the internal electrodes are recessed from end surfaces of the component main body with a recess length of about 1 μm or less. Plating films to serve as external electrodes are formed to extend from the end surfaces of the component main body across the R chamfered section, and include end edges located on at least one of the principal surfaces and the side surfaces.

摘要： When an external terminal electrode of a ceramic electronic component such as a laminated ceramic capacitor is formed by plating, plating growth may be also caused even in an undesired location. The ceramic surface provided by a component main body is configured to include a high plating growth region of, for example, a barium titanate based ceramic, which exhibits relatively high plating growth, and a low plating growth region of, for example, a calcium zirconate based ceramic, which exhibits relatively low plating growth. The plating film constituting a first layer to define a base for an external terminal electrode is formed in such a way that the growth of a plated deposit deposited with conductive surfaces provided by exposed ends of internal electrodes as starting points is limited so as not to cross over a boundary between the high plating growth region and the low plating growth region toward the low plating growth region.

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.

摘要： A region where a plating film constituting an external electrode is formed can be accurately controlled in an electronic component in which the external electrode is formed by directly plating a particular region in a surface of a component body. In a component body, a bump is provided in a position in which a region where an external electrode should be formed is partitioned. In a plating process, growth of the plating film constituting the external electrode is substantially stopped or delayed in the bump. As a result, a termination point of the growth of the plating film constituting the external electrode can be accurately controlled in the position of the bump.

摘要： A method is used to manufacture a multilayer electronic component including a multilayer composite including internal electrodes having ends that are exposed at a predetermined surface of the multilayer composite. In the method, the exposed ends of the internal electrodes are coated with a metal film primarily composed of at least one metal selected from the group consisting of Pd, Au, Pt and Ag and having a thickness of at least about 0.1 μm by immersing the multilayer composite in a liquid containing a metal ion or a metal complex. Then, a continuous plating layer is formed by depositing a plating metal on the ends of the internal electrodes exposed at the predetermined surface of the multilayer composite, and subsequently growing the deposits of the plating metal so as to be connected to each other. Thus, exposed ends of the internal electrodes are electrically connected to each other.
