A liquid curable adhesive is provided over the set of contacts of a first substrate, and the set of electrical contacts of the second substrate is aligned with the set of electrical contacts of the first substrate. The sets of electrical contacts of the first and second substrate are compressed to displace the liquid curable adhesive from the inter-contact region, and provide electrical communication between the respective sets of electrical contacts. The liquid curable adhesive is then cured to form a solid matrix which maintains a relative compression between the respective sets of electrical contacts. One embodiment of the module comprises a high-speed superconducting circuit which operates at cryogenic temperatures.Type: GrantFiled: April 17, 2012Date of Patent: August 12, 2014Assignee: Hypres Inc.Inventor: Vladimir V.

Publication number: 20140185217Abstract: A printed circuit board and a design method thereof are disclosed. The design method includes: wiring signal lines on an area basis at inner layers adjacent to outer surface layers; arranging the outer surface layers with no wiring or few wirings and interconnecting the outer surface layers through vias, so that the outer surface layers function as a primary ground; and setting parameters of a line width and a layer height to control a target impedance value. The printed circuit board includes outer surface layers and two inner layers therebetween. The inner layers adjacent to the outer surface layers are used for arranging signal lines on an area basis; and the outer surface layers are arranged with no wiring or few wirings and are interconnected as a primary ground through vias. The invention also discloses a mainboard of a terminal product using the printed circuit board.Type: ApplicationFiled: March 7, 2014Publication date: July 3, 2014Applicant: Huawei Technologies Co., Ltd.Inventors: Xiaolan SHEN, Qingsong YE, Konggang WEI

Patent number: 8760882Abstract: A wiring structure for improving a crown-like defect and a fabrication method thereof are provided. The method includes the following steps. A substrate, on which a seed layer and a patterned photoresist layer with an opening are formed, is provided. A copper layer, having a bottom covering the seed layer, is formed in the opening. A barrier layer covering at least one top portion of the copper layer is formed on the copper layer. An oxidation potential of the barrier layer is greater than that of the copper layer. The patterned photoresist layer is removed to perform an etching process, wherein the copper layer and a portion of the seed layer exposed are etched to form a wiring layer. An immersion process is performed to form an anti-oxidation layer comprehensively on exposed surfaces of the barrier layer and the wiring layer.Type: GrantFiled: November 18, 2011Date of Patent: June 24, 2014Assignee: Xintec Inc.Inventors: Yi-Ming Chang, I-Min Lin, Po-Shen Lin

Patent number: 8749989Abstract: An LTCC carrier composed of thermosetting polymer, woven glass fiber and ceramic has gold over nickel contact pads on top and bottom surfaces and conductive vias therethrough between aligned pairs of top and bottom pads. The vias prevent undesirable inductive paths from limiting high frequency operation of the circuitry. Solder deposits on the top pads attach the LTCC component, which is further secured to the carrier by epoxy, thus improving resistance to thermal stress and mechanical shock. A slot through the carrier body between top and bottom surfaces further reduces thermal stress and mechanical shock. Metallized castellations on opposite carrier sides provide additional surface area for reflow solder joints with the PCB, and a means for visually inspecting the solder joint quality. A gap in the metallization on the top layer of the carrier prevents solder spreading during multiple soldering cycles, which may result in poor solder joints.Type: GrantFiled: December 28, 2009Date of Patent: June 10, 2014Assignee: Scientific Components CorporationInventors: Harvey L.

Patent number: 8705249Abstract: Some invention embodiments relate to a method for forming a fuse which electrically connects two metal surfaces (2) that are arranged on a printed circuit board (4) next to each other and spaced apart from each other. It is provided according to the invention that the two metal surfaces (2) are each partially covered with a protective coating (5), wherein a partial region forming a contact region (2a) remains uncovered, liquid soft solder material (1) which bridges the gap between the two metal surfaces (2) is applied onto the two uncovered partial regions (2a), and the protective coating (5) in a surrounding area of the solder material (1) is removed after the soft solder material (1) has solidified, in order to form receiving regions (2b) which are wetted by the solder material (1) when the latter fuses, with the result that the solder material (1) flows off from a printed circuit board region (3) between the two metal surfaces (2) and the electrical contact formed by the solder material (1) is interrupted.Type: GrantFiled: September 1, 2010Date of Patent: April 22, 2014Assignee: Borgwarner Beru Systems GmbHInventors: Michael Luppold, Alexander Dauth
