摘要： In a method of manufacturing a laminate type electronic component, when a heat treatment is carried out after plating films, which at least partially define external electrodes, are formed by growing plated depositions deposited on exposed ends of a plurality of internal electrodes in a component main body, the presence of the plating films may not only interfere with moisture release, but may also cause blisters or bulge defects in the plating films, while moisture such as a plating solution in the component main body is removed by evaporation. To avoid such problems, cuts to divide exposed ends into multiple sections are formed in extending sections of internal electrodes. Thus, plating films include slits extending in the stacking direction at locations corresponding to positions of the cuts.

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： A method for manufacturing a laminated ceramic electronic component enables formation of a plating film as at least a portion of an external electrode which connects exposed ends of internal electrodes. A component main body including a plurality of ceramic layers and a plurality of internal electrodes partially exposed from the component main body is prepared such that the component main body has a conductive region formed by diffusion of a conductive component included in the internal electrodes at the end surfaces of the ceramic layers located between adjacent exposed ends of the plurality of internal electrodes. The ceramic layers are preferably composed of a glass ceramic containing a glass component of about 10 weight % or more. A plating film is formed directly on the component main body by growing the exposed ends of the internal electrodes and the conductive region as nucleuses for plating deposition.

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： In a laminate type ceramic electronic component, when an external electrode is formed directly by plating onto a surface of a component main body, the plating film that is to serve as the external electrode may have a low fixing strength with respect to the component main body. In order to prevent this problem, an external electrode includes a first plating layer composed of a Ni—B plating film and is first formed such that a plating deposition deposited with the exposed ends of respective internal electrodes as starting points is grown on at least an end surface of a component main body. Then, a second plating layer composed of a Ni plating film containing substantially no B is formed on the first plating layer. Preferably, the B content of the Ni—B plating film constituting the first plating layer is about 0.1 wt % to about 6 wt %.
