Patent number: 9332638Abstract: An electrically conductive path is configured from a first copper plate, a second copper plate, and solder. The first copper plate has a first bent section extended from a first joining section joined to an electrically insulative board and bent toward the rear surface of the electrically insulative board. The second copper plate has a second bent section which is extended from a second joining section joined to the electrically insulative board, is bent toward the front surface of the electrically insulative board, and is disposed so as to cover, together with the first bent section, the inner wall surface of a base-material through-hole. Through-holes are provided in the portions of the second copper plate which face the inside of the base-material through-hole. Solder is filled between the first bent section and the second bent section.Type: GrantFiled: May 23, 2012Date of Patent: May 3, 2016Assignee: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Kiminori Ozaki, Yasuhiro Koike, Hiroaki Asano, Harumitsu Sato, Hiroki Watanabe, Tadayoshi Kachi, Takahiro Suzuki, Hitoshi Shimadu, Tetsuya Furuta, Masao Miyake, Takahiro Hayakawa, Tomoaki Asai, Ryou Yamauchi

Patent number: 8917495Abstract: Provided is a circuit board manufacturing method capable of securing circuit patterns on a plate-like insulator while keeping the relative position between the circuit patterns, and also provided is a circuit board in which the relative position between a plurality of circuit patterns is kept. A first coil (30) having one turn is formed in a planar shape from a metal plate. Next, a second coil (40) having four turns is formed in a planar shape from a metal plate, wherein both of the ends (41, 42) of the coil are linked to other adjacent regions via linking portions (43, 44). A pair of the first coil (30) and the second coil (40) are then overlapped so as to face each other through a plastic plate (50) in which a plurality of prepregs are stacked, after which the links by the linking portions (43, 44) are disconnected.Type: GrantFiled: September 1, 2010Date of Patent: December 23, 2014Assignee: Kabushiki Kaisha Toyota JidoshokkiInventors: Hitoshi Shimadu, Takehiko Sawada, Tomoaki Asai, Ryou Yamauchi

Publication number: 20140251659Abstract: A circuit board, onto which an electronic component is to be mounted, is provided with insulating core substrates and patterned metal plates. The metal plates are bonded to at least one side of the insulating core substrates. The insulating core substrates and the metal plates form a laminated body, in which a gas-vent hole is provided. The gas-vent hole is formed so that when the electronic component is mounted, the gas present between the insulating core substrates and the metal plates expands and is released to a side open to the atmosphere via the gas-vent hole.Type: ApplicationFiled: July 2, 2012Publication date: September 11, 2014Applicant: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Hiroaki Asano, Yasuhiro Koike, Kiminori Ozaki, Hitoshi Shimadu, Tetsuya Furuta, Masao Miyake, Takahiro Hayakawa, Tomoaki Asai, Ryou Yamauchi

Publication number: 20140226296Abstract: This multi-layer wiring board is provided with an insulating substrate, an inner layer copper sheet, and an outer layer copper foil. The inner layer copper sheet is disposed within the insulating substrate and has been patterned. The outer layer copper foil is disposed in a state of having been patterned at the surface of the insulating substrate, is thinner than the inner layer copper sheet, and has a cross-sectional area of the current path that is smaller than the cross-sectional area of the current path of the inner layer copper sheet. As a result, provided are: a multi-layer wiring board that can flow a large current and a smaller current while suppressing an increase in the projected area of the substrate; and a method for producing the multi-layer wiring board.Type: ApplicationFiled: February 10, 2012Publication date: August 14, 2014Applicant: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Hiroaki Asano, Yasuhiro Koike, Kiminori Ozaki, Hitoshi Shimadu, Tetsuya Furuta, Masao Miyake, Takahiro Hayakawa, Tomoaki Asai, Ryou Yamauchi
