Method of mounting electronic component on substrate without generation of voids in bonding material
Patent number: 7159309Abstract: When an electronic component is mounted on a substrate, the electronic component is first placed on the substrate with a solid support interposed between the electronic component and the substrate.

A final overcoat of a material having superior electrical qualities (e.g., electrical conductivity and/or solderability) may be applied to the composite interconnection element.Type: GrantFiled: December 29, 2000Date of Patent: January 4, 2005Assignee: FormFactor, Inc.Inventors: Igor Y. Khandros, Thomas H. Dozier, Gary W. Grube, Gaetan L. Mathieu

Patent number: 6789308Abstract: A method of manufacturing a flat antenna is composed of the steps of entirely applying Ni plating to the front and back surfaces of a long metal sheet, bonding masking tapes to the front surface of the metal sheet where the Ni plating has been applied except two stripe regions, applying Au plating to the two stripe regions by dipping the metal sheet into an Au plating solution, making a plurality of conductive flat sheets by punching the metal sheet to a plurality of regions along the lengthwise direction thereof after exfoliating the masking tapes, and bending the portions of each conductive flat sheet acting as a power feed terminal and a ground terminal. The metal sheet can be simply masked by bonding a plurality of the masking tapes thereto linearly except the regions where the plating is to be applied, thereby the productivity of the flat antenna can be increased.Type: GrantFiled: June 14, 2002Date of Patent: September 14, 2004Assignee: Hitachi Cable, Ltd.Inventors: Shinichi Takaba, Takahiro Sugiyama, Shinichiro Suzuki, Morihiko Ikegaya

Publication number: 20040172818Abstract: A solder mask manufacturing method adapted to apply a solder mask on a surface of a substrate of a circuit board, said surface is provided with a conductor pattern having an unsheltered portion and a sheltered portion which is covered by said solder mask. The method comprises the steps of: a) disposing a layer of semi-solid solder mask material having an expansion coefficient substantially the same as that of the substrate on the surface of said substrate to cover said copper conductor pattern, and a metal foil covering the material layer; b) applying pressure to the metal foil and applying baking treatment to cure the solder mask material in to solid; c) utilizing chemical solution and plasma etching to remove the metal foil and the solid solder mask material above the unsheltered portion of said copper conductor pattern respectively such that the unsheltered portion can be exposed; and d) using chemical solution to remove the residual metal foil.Type: ApplicationFiled: March 16, 2004Publication date: September 9, 2004Applicant: S & S Technology CorporationInventors: Chong-Ren Maa, Wan-Kuo Chih, Ming-Sung Tsai

Publication number: 20040168315Abstract: The invention comprises filling a conductive adhesive on a hole end of a wire connection part in tubular shape of the terminal which has an electric contact part at one side and the wire connection part at the other side, inserting an electric wire from a hole opening of the wire connection part toward the hole end, and reducing evenly a size of a tubular wall of the wire connection part, thereby causing the conductive adhesive to infiltrate into a space of the electric contact part or between wires. The invention also comprises tightening the tubular wall of the wire connection part by a rotary swaging process. Further, the conductive adhesive is a nickel paste which is a mixture of nickel powders in a liquid epoxy resin based binder. In addition, at least one of a core wire portion of the electric wire or the terminal is aluminum or aluminum alloy.Type: ApplicationFiled: December 22, 2003Publication date: September 2, 2004Applicant: YAZAKI CORPORATIONInventor: Masanori Onuma

Publication number: 20040147825Abstract: A method of forming a device, such as an electrode array for a cochlear implant. The method comprises a step of forming a predetermined pattern of relatively electrically conductive regions and relatively electrically resistive regions in a sheet of biocompatible electrically conductive material, such as platinum foil. The method can comprise a step off working on the sheet to remove predetermined portions therefrom to form the one or more discrete relatively conducting regions. The step of working on the sheet can comprise embossing the sheet, cutting or slicing the sheet, or using electrical discharge machining (EDM) to remove unwanted portions of the sheet, the EDM equipment having a cutting tool comprising an electrode.Type: ApplicationFiled: November 7, 2003Publication date: July 29, 2004Inventors: Dusan Milojevic, John Parker

Publication number: 20040123457Abstract: By forming a terminal at a tip of a lead part of a lead frame, and by fixing this terminal and a connecting pad which was formed on an upper surface of a first printed circuit board, the lead frame is attached to the first printed circuit board. By cutting off a frame part and a tie bar part from the lead frame which was attached to the first printed circuit board, the lead part is separated, and forming is applied to the lead part so as for its tip to be extended over the first printed board. After the lead part which is expanded upward is inserted into a through-hole which was opened in a second printed circuit board, by soldering the lead part and the through-hole, the first printed circuit board and the second printed circuit board are electrically connected.Type: ApplicationFiled: October 9, 2003Publication date: July 1, 2004Applicants: FUJITSU TEN LIMITED, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takashi Ohta, Kazuaki Yamada, Kiyoshi Tsujii, Hidekazu Manabe

Patent number: 6751849Abstract: A movable contact arrangement suitable for use in a switching device has a rigid contact body and a flexible conductor piece connecting the contact body to a fixed conductor. The contact body is connected to the conductor piece by mechanically compressing a section of a semifinished product in the form of a cable or strand, with the flexible conductor piece being formed by an uncompressed part of the semifinished product. The compressing operation can also be used at the same time to produce the contact body from the semifinished product. The method described allows low-cost production of contact modules for power circuit breakers used in sophisticated mechanical and electrical equipment.Type: GrantFiled: July 20, 2001Date of Patent: June 22, 2004Assignee: Siemens AktiengesellschaftInventors: Ulrich Helmke, Harald Kurzmann
