Patent number: 6896525Abstract: A socket for testing integrated circuit has opposite cantilever probing pads hinged at the far ends of the cantilevers to a circuit board. The leads of the IC are pressed over the free nearer ends of the cantilevers. Cushions are inserted under the two free nearer ends of the cantilevers to absorb in the pressure of the IC leads. For in-line lead IC packages, a common cushion can be used for each line of leads. Metallic pedestals can be mounted on the between the nearer ends of the cantilever and touching the IC under test for heat sinking and common ground. The pedestals can be inserted through the circuit board from a base plate at the bottom of the circuit board.Type: GrantFiled: December 16, 2002Date of Patent: May 24, 2005Assignee: Eutrend Technology Inc.Inventor: Ying-Fan Kuo

Patent number: 6812060Abstract: The present invention provides bumpless ultrasonic bonding of flexible wiring board pieces. A metal coating 26 is formed on the surface of a contact region 181 of a metal wiring 28 of each of two flexible wiring board pieces 10, 30 and ultrasonic wave is individually applied by an ultrasonic resonator 45 to the contact regions 181 in contact with each other. The metal coatings 26 are bonded to form a multilayer flexible wiring board 50. The bumpless process eliminates any plating step for forming bumps without being influenced by non-uniformity bump height. A thermoplastic resin film 33 may be formed on the surface of one flexible wiring board piece 30 to bond flexible wiring board pieces 10, 30 by the adhesion of the resin film 33.Type: GrantFiled: October 16, 2000Date of Patent: November 2, 2004Assignee: Sony Chemicals CorporationInventors: Hideyuki Kurita, Hiroyuki Hishinuma

Patent number: 6702589Abstract: An apparatus for mounting a semiconductor device to a circuit board for testing is disclosed. The semiconductor device includes semiconductor circuitry and leads to connect the semiconductor circuitry to the circuit board. Additionally, the semiconductor device is decapped so that at least a portion of the semiconductor circuitry is exposed. The apparatus includes a frame and a fastener. The frame is adapted to mate with the semiconductor device, and forms an opening for accessing the semiconductor circuitry and an edge surface for receiving the semiconductor device. The fastener is connected with the frame for removably connecting the frame to the circuit board. By using a frame instead of a socket, the distance to the semiconductor device once the device is mounted to the circuit board, and particularly the top side of the semiconductor device, can be reduced so that the device may be tested using a probe.Type: GrantFiled: August 16, 2002Date of Patent: March 9, 2004Assignee: Infineon Technologies AGInventors: David SuitWai Ma, Bing Ren, James J.

Patent number: 6672912Abstract: An integrated circuit socket includes one or more cavities formed in a top surface of the socket, where the one or more cavities are formed in a region over which an integrated circuit can be placed. Multiple conductive contacts are attached to the socket, where each contact includes a first member that extends into one of the cavities, and a second member that provides at least part of a conductive path between the first member and the socket. The first member at least partially holds in place a discrete device inserted into the cavity. An integrated circuit package or interposer attached to the top surface over the cavity also can at least partially hold the discrete device in place. The first member makes electrical contact with the discrete device, thus completing a conductive path between the discrete device and the integrated circuit.Type: GrantFiled: March 31, 2000Date of Patent: January 6, 2004Assignee: Intel CorporationInventor: David G.
