Publication number: 20140015558Abstract: A current applying device is provided in which a contact body which surface-contacts with an inspection target body makes contact with the surface of the inspection target body uniformly; current can be favorably applied from the contact body to the inspection target body; and the contact body alone can be replaced. A probe device 1 for applying current by being in pressure-contact with the power semiconductor H includes: a contact body 2 which surface-contacts with the power semiconductor H; and a plurality of electrically-conductive two-tier springs 31 which press the contact body 2 onto the power semiconductor H; the contact body 2 and the plurality of electrically-conductive two-tier springs 31 are separate bodies, and the plurality of electrically-conductive two-tier springs 31 electrify the contact body 2 while providing pressing force F to each of a plurality of sections of the contact body 2.Type: ApplicationFiled: July 5, 2013Publication date: January 16, 2014Inventors: Shigeto Akahori, Hiroyuki Yamagishi, Satoshi Hasegawa, Yoko Yamaji, Nobuo Kambara, Shinyu Hirayama

Patent number: 8624616Abstract: A suspended IO trace design for SSP cantilever Read/Write is described. Instead of having the whole I/O trace attached to surface of the cantilever, the cantilever is designed with fish-bone-like support and the I/O traces are anchored to cantilever structures 110 at some specific attachment locations with dielectric insulation in between. This design provides very compliant trace compared to cantilever's see-saw actuation around the torsional beam pivot and is also insensitive to residual stress variations from I/O trace in fabrication.Type: GrantFiled: July 1, 2008Date of Patent: January 7, 2014Assignee: Intel CorporationInventors: Tsung-Kuan Allen Chou, David Harrar, II

Patent number: 8618828Abstract: In a connection structure of an electronic component and a wired circuit board, the electronic component includes a plurality of external terminals. The wired circuit board includes a metal supporting board, an insulating base layer formed on the metal supporting board, and a conductive pattern formed on the insulating base layer. The conductive pattern includes a plurality of terminal portions for connection with the plurality of external terminals. The electronic component and the wired circuit board are disposed such that the plurality of external terminals and the plurality of terminal portions face each other. The wired circuit board is bent such that the conductive pattern is warped, and by the reaction force of the warping, the terminal portions and the external terminals are abutted, and the electronic component and the wired circuit board are electrically connected.Type: GrantFiled: November 18, 2010Date of Patent: December 31, 2013Assignee: Nitto Denko CorporationInventors: Tetsuya Ohsawa, Hitoki Kanagawa

Publication number: 20130342234Abstract: Probes are directly patterned on a test substrate, thereby eliminating a need for an interposer. Probe contact structures are formed as a two-level structure having a greater lateral dimension for a lower level portion than for an upper level portion. First cavities are formed in a masking layer applied to a test substrate, filling the cavities with a conductive material, and planarizing the top surfaces of the conductive material portions to form lower level portions. Another masking layer is applied over the lower level portions and patterned to define second cavities having a smaller lateral dimension that the lower level portions. The second cavities are filled with at least one conductive material to form upper level portions of the probe contact structures. The upper level portion of each probe contact structure can be employed to penetrate a surface oxide of solder balls.Type: ApplicationFiled: June 21, 2012Publication date: December 26, 2013Applicant: Intenational Business Machines CorporationInventors: David M.

Publication number: 20130335111Abstract: A probe for transporting a nondestructive inspection sensor through a tube, that employs wheels to reduce friction. The radial travel of the wheels are mechanically linked through a cam and axially reciprocal plunger arrangement that centers the probe at tube diameter transitions. Internal wire bending is minimized and a dynamic seal is provided to facilitate an insertion force at the probe and reduce or eliminate compressive load buckling of the flexible cable carried by the probe. Like the wheel arrangement, radial travel of the seal segments are mechanically linked to provide probe centering.Type: ApplicationFiled: March 12, 2013Publication date: December 19, 2013Applicant: WESTINGHOUSE ELECTRIC COMPANY LLCInventor: WESTINGHOUSE ELECTRIC COMPANY LLC
