  • Patent number: 8179225
    Abstract: A ceramic electronic component has a chip element body having a conductor arranged inside, external electrodes, and a discrimination layer. The chip element body has first and second end faces facing each other, first and second side faces being perpendicular to the first and second end faces and facing each other, and third and fourth side faces being perpendicular to the first and second end faces and to the first and second side faces and facing each other. The external electrodes are formed on the first and second end faces, respectively, of the chip element body. The discrimination layer is provided on at least one side face out of the first side face and the second side face in the chip element body. The chip element body is comprised of a first ceramic. The discrimination layer is comprised of a second ceramic different from the first ceramic and has a color different from that of the third and fourth side faces.

  • Patent number: 7799409
    Abstract: A ceramic green sheet structure has a ceramic green sheet including at least a ceramic material and a resin and a conductive layer formed on the ceramic green sheet. An electrode non-formed area has a porosity equal to or greater than 17%, and preferably, equal to or less than 25%. Moreover, an electrode formed area where the conductive layer is formed may have a smaller porosity than the electrode non-formed area where no conductive layer is formed.

  • Patent number: 7751176
    Abstract: A ceramic electronic component includes a ceramic body and an internal electrode layers disposed within the ceramic body. The ceramic body is covered with a diffusion layer, wherein said diffusion layer is an oxide layer into which at least a part of elements contained in the ceramic body are diffused and is located closer to a surface of the ceramic body than an outermost internal electrode layer.

  • Patent number: 7735713
    Abstract: A method for mounting a chip component includes the steps of: flattening a solder deposit adhering onto a land terminal of a circuit board; forming grooves on the solder deposit simultaneously with or after flattening the solder deposit; coating the solder deposit with a flux; and placing a chip component on the solder deposit with the flux interposed therebetween.

  • Publication number: 20090211687
    Abstract: The present invention aims to provide a method for manufacturing a multilayer electronic component capable to remove a multilayer body very easily from the press mold without breaking the multilayer body when removing a green sheet multilayer body applied with a pressure from the press mold, furthermore has no waste of material, contributes to the environment conservation, and also easy to automate. Among the plurality of green sheets constituting a multilayer body 4a, the adhesive force of at least one of the outer green sheet 14a1 contacting to the lower mold 20 of the press mold 20 is made weaker compared to that of other green sheet 14a2, 10a, 14a3, and 14a4 of which are stacked with said outer green sheet 14a1. Next, a pressure is applied to the multilayer body 4a on the lower mold 20 of the press mold. Then, the press mold 25 is removed from the multilayer body 4a which is applied with the pressure.

  • Patent number: 7177138
    Abstract: A chip-type electronic component comprises a chip element body including an inner circuit element, and a pair of terminal electrodes electrically connected to the inner circuit element. The pair of terminal electrodes are positioned at respective end portions of the chip element body. The chip element body has one side face acting as a mounting surface opposing a circuit substrate. The pair of terminal electrodes include an electrode portion formed on the mounting surface. Here, it is assumed that a first direction is a direction orthogonal to the mounting surface, a second direction is a direction along which the pair of terminal electrodes oppose each other on the mounting surface, and a third direction is a direction orthogonal to the first and second directions.
