  • Patent number: 7291928
    Abstract: Semiconductor chips are connected to electrode terminals (6a, 6b) by wire bonding, and connecting conductors connect extending portions (60b, 60c) extending from a part of the electrode terminals (6b, 6c) to the circuit patterns (3a, 3b) by soldering, and thus the wire bonding points of the electrode terminals are reduced to thereby reduce an electric resistance and suppress heat generation and voltage drop.
    Type: Grant
    Filed: August 27, 2003
    Date of Patent: November 6, 2007
    Assignee: Mitsubishi Denki Kabushiki Kaisha
    Inventors: Junji Yamada, Seiji Saiki
  • Publication number: 20060048966
    Abstract: A shield cable, in which a winding looseness of a shield layer due to twisting can be decreased and a short-circuit between a shield layer and signal conductor as well as a disconnection of the signal conductor is prevented, and a wiring component and information apparatus having the shield cable are provided. A twisted conductor is covered with an insulator to form an insulated wire with an outer diameter of 0.3 mm or less. This insulated wire is covered with a shield conductor and a sheath so as to form a shield cable. The shield conductor consists of a plurality of shield layers. The first shield layer at an inner most part is formed by winding conductors spirally with a scroll pitch of 7 to 13 mm. One shield cable may contain two insulated wires.

  • Patent number: 6984883
    Abstract: An insulating substrate (17) includes a surface conductive layer (25) fixedly laminated on a surface of the plate-like semiconductor body (21) via a surface side fixing member (24, 26). The surface side fixing member (24, 26) includes a first fixing portion (26) for fixing one part (25a) of the surface conductive layer (25) located underneath the joint portion (15) of the electrode terminal (14), and a second fixing portion (24) for fixing the other part (25b) of the surface conductive layer (25) which is not located underneath the joint portion (15), and a fixing strength exhibited by the first fixing portion (26) is smaller than that exhibited by the second fixing portion (24).
