Patent number: 6771517Abstract: Apparatus and methods for reducing circuit board flexing is presented. The apparatus is fastened to a printed circuit board to provide rigid support for reducing bending and flexing. In one embodiment, a rigid frame is provided that is adapted to be fastened to one or more components and to be fastened to a printed circuit board. The frame is adapted to elevate the attached component from the PCB surface allowing components to be mounted on the PCB therewith. The frame is adapted to occupy minimal printed circuit board surface area so as not to displace electronic components. In another embodiment, an elongated truss-like stiffener is provided that is adapted to be fastened to one side of the printed circuit board and adapted to span the printed circuit board. The elongated stiffener is adapted to have an open structure to minimize cooling flow disturbance and weight. The elongated stiffener includes a plurality of legs forming a truss-like structure.Type: GrantFiled: July 26, 2002Date of Patent: August 3, 2004Assignee: Silicon Graphics, Inc.Inventors: Thomas Alex Crapisi, Jeffrey Scott Cogner, Stephen Cermak, III, Stephen A. Bowen, Rodney Ruesch, David Paul Gruber, Bonnie Kay Dobbs

Patent number: 6726505Abstract: New methods and configurations are provided that allow for a large memory capacity, as well as minimized interconnect distances between the memory chips and one or more processors, and the HUB chip-set. The apparatus, configurations and methods include providing a printed circuit board having one or more processor conductive portions and one or more z-axis connector conductive portions in close proximity with each other, and connecting the one or more processors on one side of a printed circuit board, and connecting the one or more z-axis connectors for the memory daughter cards on the opposite side of the processor board. Standoffs are used to support and secure the horizontally disposed z-axis memory daughter cards and to ensure proper spacing between the z-axis daughter cards and the processor board Standoffs include an alignment pin portion and a spacer portion. The alignment pin portion includes an alignment portion, foot, and urging portion.Type: GrantFiled: August 29, 2002Date of Patent: April 27, 2004Assignee: Silicon Graphics, Inc.Inventors: Stephen Cermak, III, Jeffrey S. Conger, David Paul Gruber, Thomas Alex Crapisi, Stephen A. Bowen, Steven Shafer, Mark Ronald Sikkink

Patent number: 6487082Abstract: A printed circuit board apparatus, configurations and methods are presented which provide for close spacing between the HUB and multiple processors as well as a common configuration for two or four processor boards. A printed circuit board is provided with conductive apertures and portions corresponding to an efficient Packaging allowing for the attachment of the processor-chip on one side of the printed circuit board, and the HUB and other supporting electronic components on the other side of the printed circuit board. This configuration allows for the close spacing of the electrical conductors of the HUB and the processors without the limitations imposed by the physical dimensions of the respective hardware. Additionally, a symmetric packaging of the conductive apertures and portions about a centerline of the printed circuit board allows for a simple design modification to allow for a two two-processor board to be manufactured from a similarly configured four-processor board.Type: GrantFiled: July 20, 2000Date of Patent: November 26, 2002Assignee: Silicon Graphics, Inc.Inventors: Thomas Alex Crapisi, Jeffrey S.

Patent number: 5963428Abstract: The present invention discloses a method and apparatus for bridging the gap between an integrated circuit package or component mounted on a circuit board and a heat sink such that there is little stress placed on the component, but there is still a connection between the component and the heat sink for dissipation of heat. The invention provides mechanical integrity for delicate component packages, and in doing so allows for the use of a variety of heat sinks to provide cooling. A printed circuit board has integrated circuit packages or other components mounted to the circuit board. A cooling cap comprised of a thermally conductive material is mounted on the circuit board, such that the component is enveloped by the circuit board and cooling cap. A layer of thermally conductive material may be deposited between the component and the cooling cap to provide a thermally conductive path from the component to the cooling cap.Type: GrantFiled: August 20, 1998Date of Patent: October 5, 1999Assignee: Cray Research, Inc.Inventors: Richard B. Salmonson, Stephen Cermak, III

Patent number: 5131859Abstract: A circuit board module for a supercomputer includes quick connections for power, ground, coolant quick connects, and circuit quick connects. The quick connections provide for insertion of modules with substantial savings in time and effort. The electrical power and ground connections and the liquid coolant connections engage and disengage automatically upon insertion and removal of the modules. The circuit quick connects require only insertion of a camming tool for connection and disconnection. The modules require no bolting or unbolting of clamps or hoses for the various connections.Type: GrantFiled: March 8, 1991Date of Patent: July 21, 1992Assignee: Cray Research, Inc.Inventors: Stephen A.
