A further aspect is a provision for encasing each connector assembly or stack inside a thermoset layer or a thermoplastic layer before over-molding the same to a sealed housing.Type: ApplicationFiled: April 10, 2009Publication date: October 15, 2009Inventors: Farshid Dilmaghanian, Hugh Cook

Publication number: 20090243105Abstract: In semiconductor devices having a copper-based metallization system, bond pads for wire bonding may be formed directly on copper surfaces, which may be covered by an appropriately designed protection layer to avoid unpredictable copper corrosion during the wire bond process. A thickness of the protection layer may be selected such that bonding through the layer may be accomplished, while also ensuring a desired high degree of integrity of the copper surface.Type: ApplicationFiled: February 5, 2009Publication date: October 1, 2009Inventors: Matthias Lehr, Frank Kuechenmeister

Patent number: 7581961Abstract: Method for preventing solder from rising to a portion of an electric contact when the electric contact is being soldered to a copper foil so as to extend therefrom. The portion is plated with a noble metal and adapted to contact a mating object. Cooling means is brought into contact with at least the portion of the electric contact adapted to contact the mating object, and connection portion between the electric contact and the copper foil is heated by heating means. The rising of solder can be prevented and the electric contacts thus obtained are superior in mechanical property (sufficient bonding strength), electrical property (conductive property and low contact resistance), resistance to environmental conditions (impediment to oxidization), and physical property (limitation of rise of solder due to capillary action).Type: GrantFiled: August 9, 2007Date of Patent: September 1, 2009Assignee: Fujikura Ltd.Inventors: Tomonari Ohtsuki, Katsuya Yamagami

Publication number: 20090144975Abstract: A method of producing a flexible circuit according to an embodiment herein include supplying a substrate layer film and supplying a cover layer film. A conductive ink is printed on at least a portion of the substrate layer film using an ink jet printing technique. The cover layer film is then laminated over the substrate layer film to provide the flexible circuit. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.Type: ApplicationFiled: February 17, 2009Publication date: June 11, 2009Inventor: Norman P.

Patent number: 7530826Abstract: A method and apparatus for creating a sealed cavity includes a housing assembly (100) incorporating a molded connector (110) with an interior portion formed into a cavity (170) and a vent hole (160) that communicates with the cavity (170). The vent hole (160) permits escape of gas generated by solidification of sealant (410) used to attach lid (410) to housing lid seat (120). The vent hole (160) further prevents contaminants from reaching the cavity interior until the final connector seal is applied. The vent hole (160) can be interfaced with a final applied mating sealed connector which utilizes the mating connector seal to provide the final cavity seal. The molded connector (110) can then be adapted with a sensor module which circumvents the need for sealing the small vent hole (160) using additional processes.Type: GrantFiled: September 15, 2006Date of Patent: May 12, 2009Assignee: Honeywell International Inc.Inventor: Gregory J. Zeigler

Publication number: 20090050488Abstract: The present invention relates to electrolytic cathode assemblies typically used in the refining or winning of metals and to methods of manufacturing and using same. The cathode assembly comprises an electrically conductive hanger bar and a deposition plate attached along an upper end to the hanger bar to define a joint. The cathode assembly further comprises a protective covering having lateral edges and surrounding the hanger bar and a portion of the upper end of the deposition plate so as to substantially enclose the joint and to leave end portions of the hanger bar exposed outside of the lateral edges of the protective covering. Each end of the protective covering includes a corrosion resistant material positioned to form a substantially continuous seal between the protective covering and the hanger bar, thereby to at least hinder fluid flow into the protective covering. Methods of manufacturing and using the electrolytic cathode assemblies are also described.Type: ApplicationFiled: August 24, 2007Publication date: February 26, 2009Applicant: EPCM Services ltd.Inventors: Robert Stanley Jickling, Gordon Steven Iverson
