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 of forming a plating layer for an external terminal electrode by applying, for example, copper plating to an end surface of a component main body with respective ends of internal electrodes exposed, and then applying a heat treatment at a temperature of about 1000° C. or more in order to improve the adhesion strength and moisture resistance of the external terminal electrode, the plating layer may be partially melted to decrease the bonding strength of the plating layer. In the step of applying a heat treatment at a temperature of about 1000° C. or more to a component main body with plating layers formed thereon, the average rate of temperature increase from room temperature to the temperature of about 1000° C. or more is set to about 100° C./minute or more. This average rate of temperature increase maintains a moderate eutectic state in the plating layer and ensures a sufficient bonding strength of the plating layer.

摘要： A method for manufacturing a laminated electronic component in which, when first plating layers that respectively connect a plurality of internal electrodes to each other and second plating layers that improves the mountability of a laminated electronic component are formed as external terminal electrodes, the entire component main body is treated with a water repellent agent after the formation of the first plating layers, and the water repellent agent on the first plating layers is then removed before the formation of the second plating layers. The gaps between the end edges of the first plating films on the outer surface of the component main body and the outer surface of the component main body are filled with the water repellent agent.

摘要： In an electronic component, a laminate includes a plurality of laminated ceramic layers and a mounting surface defined by outer edges of the plurality of laminated ceramic layers, the outer edges being continuously located adjacent to each other. Capacitor conductors are disposed on the ceramic layers and include exposed portions that are exposed at the mounting surface between the ceramic layers. An electroconductive layer defining an external electrode is arranged to directly cover the exposed portions and is formed by plating so as to be made of plated material. Another electroconductive layer covers the above-mentioned electroconductive layer and partially covers surfaces of the laminate, and it is made of a material including metal and one of glass and resin.

摘要： A laminate includes ceramic layers laminated to each other. Internal conductors are embedded in the laminate and include exposed portions that are exposed between the ceramic layers at a lower surface and an upper surface of the laminate. External electrodes are directly plated on the lower surface and the upper surface so as to cover the respective exposed portions. Regions of the lower surface at which the exposed portions are provided are arranged to protrude from the other regions of the lower surface, and regions of the upper surface at which the exposed portions are provided are arranged to protrude from the other regions of the upper surface.

摘要： A laminated electronic component includes a first plating film that defines a base for external terminal electrodes and that includes a plurality of layers including a first layer made of, for example, copper and a second layer provided on the first layer. The total thickness of the first plating film is about 3 μm to about 15 μm, and the thickness of the second layer is about 2 to 10 times as thick as the thickness of the first layer. The first layer is formed by electroless plating, and the second layer is formed by electrolytic plating. This formation results in a grain size of about 0.5 μm or more of a metal grain included in the second layer, and thus makes the film less susceptible to oxidation.
