Patent number: 7325299Abstract: A method of making a circuitized substrate. A conductive layer having a substantially planar upper surface is formed on and in direct mechanical contact with an upper surface of a substrate. A portion of the conductive layer is removed to form an interim side wall in the conductive layer. A layer of patternable material is formed on the substantially planar upper surface and on the interim side wall. A portion of the layer of patternable material on the conductive layer is removed to expose the interim side wall. A portion of the substantially planar upper surface is removed to form a side wall in the layer of patternable material. Portions of the interim side wall in the conductive layer are removed to form a second side wall and a bottom wall defined by the upper surface of the substrate. The second side wall is substantially perpendicular to the bottom wall.Type: GrantFiled: January 4, 2007Date of Patent: February 5, 2008Assignee: International Business Machines CorporationInventors: Frank D.

Patent number: 7290333Abstract: A conductive film has a plurality of clearances (openings) and a plurality of auxiliary clearances. The plurality of clearances and the plurality of auxiliary clearances are formed to have such numerical apertures and locations that generate no bias in the distribution of conductive film in consideration of the entire conductive film. The conductive film can disperse stress caused by thermal expansion etc., to ease by having the plurality of clearances and the plurality of auxiliary clearances. Accordingly, the conductive film is less prone to being peeled off the insulating film. Further, since the distribution of conductive film is substantially uniform as a whole, the transfer characteristics that are fixed by the distribution become substantially uniform as a whole.Type: GrantFiled: December 3, 2004Date of Patent: November 6, 2007Assignee: NEC CorporationInventor: Isao Matsui

Patent number: 7290330Abstract: A system including a circuit board and several pluggable modules coupled to the circuit board. The several pluggable modules are insertable through side-by-side slots in an enclosure in which the circuit board resides. A first pluggable module is coupled to the circuit board via a first connector, while a second pluggable module is coupled to the circuit board via a second connector such that the second pluggable module is laterally offset from the first pluggable module. The first and second connectors are right angle connectors, and the second right angle connector is inverted relative to the first right angle connector. The first and second pluggable modules are I/O modules for transporting high speed differential signals, and wherein the first pluggable module includes several XFP connectors, and wherein the second pluggable module includes several SFP connectors. The second pluggable module includes several SFP connectors arranged on both sides of the pluggable module.Type: GrantFiled: April 26, 2005Date of Patent: November 6, 2007Assignee: EMC CorporationInventors: Steven D.

Patent number: 7284321Abstract: A method for testing a chip with a package having connecting pins and mounting the package on a board combines the advantages of a package with inline connecting pins with that of a package with offset connecting pins. The package with inline connecting is inserted into a socket for testing. Before mounting on the board, at least one connecting pin, preferably every second connecting pin, of the package is bent inward by a bending tool to achieve an offset arrangement of the connecting pins. The package is preferably mounted on the board using the bending tool. Since every second connecting pin is not bent inward immediately before insertion of the connecting pins, no subsequent corrective alignment of the offset connecting pins is required.Type: GrantFiled: May 17, 2005Date of Patent: October 23, 2007Assignee: Micronas GmbHInventors: Wolfgang Hauser, Heiko Dreher, Christian Kimstedt, Markus Rogalla

Patent number: 7263770Abstract: Provided is an electrical connector having first and second surfaces and configured to establish electrical communication between two or more electrical devices. The electrical connector includes an insulative housing and a resilient, conductive contact retained in an aperture disposed from the first surface to the second surface. To contact the electrical devices, the contact includes a center portion from which extends two diverging, cantilevered spring arms that project beyond either surface of the electrical connector. To shorten the path that current must travel through the contact, one spring arm terminates in a bellows leg that extends proximate to the second spring arm. When placed between the electrical devices, the spring arms are deflected together causing the bellows leg to press against the second spring arm. For retaining the contact within the aperture, the contact also includes retention members extending from the center portion that engage the insulative housing.Type: GrantFiled: January 4, 2005Date of Patent: September 4, 2007Assignee: Cinch Connectors, Inc.Inventors: David W. Mendenhall, Hecham K. Elkhatib, Richard Miklinski, Jr.
