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 %.

摘要： In a laminate type ceramic electronic component, when an external electrode for a laminated ceramic capacitor is formed directly by plating onto a surface of a component main body, the film that is directly plated may have a low fixing strength with respect to the component main body. As the external electrode, a first plating layer composed of a Ni—P plating film with a P content rate of about 9 weight % or more 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 P is formed on the first plating layer. Preferably, the first plating layer is formed by electroless plating, whereas the second plating layer is formed by electrolytic plating.

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.

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： 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.
