Patent number: 5953214Abstract: An electronic package assembly for being electrically connected to a conducting member (e.g., a printed circuit board) wherein the assembly includes a pair of substrates. The first substrate includes opposing circuit patterns, those on one surface being of higher density and thus adapted for having high density electronic devices mounted thereon. This high density pattern is electrically coupled to the lesser density second pattern which is connected to contacts of a second substrate. These contacts are of the lesser density also, and extend through a dielectric member for being coupled to conductors (e.g., copper circuit pads) on the conducting member. Ready separability of various parts of the assembly is thus assured.Type: GrantFiled: May 24, 1996Date of Patent: September 14, 1999Assignee: International Business Machines CorporationInventors: David William Dranchak, Robert Joseph Kelleher, David Peter Pagnani, Patrick Robert Zippetelli

Footprints designated in the layout receive components which provide the option flexibility of mother board 10M. Memory module connectors are to be emplaced within the memory region depending on the space requirements of component options. The M memory connectors may be arranged in any configuration selected from a set of multiple possible configurations permitted by M module connectors of T types emplaced in F footprint sites (where F>M). F minus M footprint sites remain vacant without a module connector emplaced therein. These vacant sites provide empty spaces which may be "shuffled around" to accommodate the various system component options.Type: GrantFiled: December 7, 1995Date of Patent: December 30, 1997Assignee: Micronics Computers Inc.Inventor: Xiao Feng Zhu

Patent number: 5703759Abstract: An electrically reconfigurable multi-chip module (MCERD) comprises three electrically reconfigurable integrated circuits (ERICs) enclosed in a package. The package provides for more "extra-package" connections between the ERICs and package pins than it does "intra-package" inter-chip connections. However, configuration connections between ERICs are intra-package. The MCERD is mounted on a daughterboard which provides connections between package pins and between package pins and pins of the daughterboard. The connections between package pins define "extra-package inter-chip" connections that typically far exceed the number of intra-package inter-chip connections. The connections between package pins and daughterboard pins connect the MCERD to a host system when the daughterboard is mounted on the host system motherboard. When the MCERD and daughterboard are installed in a host system, the MCERD can be electrically configured and then operated as configured.Type: GrantFiled: December 7, 1995Date of Patent: December 30, 1997Assignee: Xilinx, Inc.Inventor: Stephen M.

Patent number: 5692913Abstract: A PC card wherein a housing of a socket connector is provided with a guide boss and a stopper protruding on the circuit board side, and with a cutout for fitting the guide boss in the circuit board. In this cutout the guide boss is fitted to position the socket connector in the direction of x. And the forward end of this stopper is held in contact with the circuit board to position in the direction of y, thus facilitating positioning of a socket connector in relation to a circuit board without a fear of socket connector displacement in subsequent processes.Type: GrantFiled: March 8, 1996Date of Patent: December 2, 1997Assignee: Alps Electric Co., Ltd.Inventors: Yasunari Takano, Hidehiro Nakamura, Shin Yoshida

Patent number: 5687064Abstract: A integrated circuit card having a rigidized frame to surround the electronic devices on a printed circuit (PC) board. The card includes a frame and integral cover for the top and bottom. The top and bottom are constructed out of a material that does not interfere with the use of an antenna coupled to the board assembly within the card. The bottom and top are coupled together using pins. When the two are coupled together the frame is better supported.Type: GrantFiled: June 20, 1996Date of Patent: November 11, 1997Assignee: Wireless Access, Inc.Inventor: Jeffreys R. Nichols

Patent number: 5686697Abstract: A device and method wherein electrical components are mechanically suspended and electrically interconnected in an insulative elastomeric body, such as silicone, thereby eliminating the need for a circuit board or other circuit substrate. The device can change shape through compression, distension, flexure, and other external forces while maintaining its electrical performance and mechanical integrity. The device can be compressed and deformed to fit snugly within another device, such as the shell of an electrical connector or a plastic clamshell, simultaneously creating spring forces for reliable electrical contacts and an environmental seal. Accordingly, the device and method can be used for a wide variety of purposes such as electrical filtering for avionics, computer or automotive connectors, or a non-intrusive manner to package electronics for medical implants.Type: GrantFiled: January 6, 1995Date of Patent: November 11, 1997Assignee: Metatech CorporationInventors: Paul J. Miller, Kevin G. Foreman

Patent number: 5650921Abstract: An electronic component assembly including a connector hole built as part of an enclosure serving as a cabinet of electronic device, where the connector hole is used for passing through an electric connector connecting a component inside the cabinet to an external device installed outside the cabinet, has a knurled portion with a plurality of dents provided around the inside of the hole for preventing the connector from rotating by engaging the corners of the flange in the connector with any of the dents. As a result, other parts, including a rear terminal assembly for preventing the connector from rotating, and the number of the assembly operations can be eliminated. The cost and processes of molding other parts can also be eliminated.Type: GrantFiled: June 16, 1995Date of Patent: July 22, 1997Assignee: Sony CorporationInventors: Yumi Imaizumi, Ryoji Naito, Scott Pinizzotto
