Patent number: 9111690Abstract: 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 ?m 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.Type: GrantFiled: August 19, 2009Date of Patent: August 18, 2015Assignee: Murata Manufacturing Co., Ltd.Inventors: Akihiro Motoki, Makoto Ogawa, Toshiyuki Iwanaga, Akihiro Yoshida, Takayuki Kayatani

Patent number: 8587919Abstract: 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.Type: GrantFiled: August 12, 2011Date of Patent: November 19, 2013Assignee: Murata Manufacturing Co., Ltd.Inventors: Makoto Ogawa, Akihiro Motoki, Takehisa Sasabayashi, Takayuki Kayatani
