| 20090210190 | HEAT SINK METHOD, SYSTEM, AND PROGRAM PRODUCT - Where an attachment means connects a heat sink to a system component, heat is thereby conducted to the heat sink from the component, a temperature sensor is located on the heat sink and another on the component or the attachment means, a portion of the attachment means is disposed between the sensors. Temperature readings from the sensors are compared to identify a failing one of the heat sink, the attachment means portion, and the component, with respect to heat conduction. Corrective action may be identified, and self-power means may also be provided to supply operative power. A wireless output circuit may be provided. Multiple heat sink sensors may be provided in any element. Rate-of-rise temperature readings may be observed and compared, including to historical values. | 08-20-2009 |

| 20080239683 | Method and Apparatus for Electrically Connecting Two Substrates Using a Land Grid Array Connector Provided with a Frame Structure Having Power Distribution Elements - A method and apparatus for electrically connecting two substrates using a land grid array (LGA) connector provided with a frame structure having power distribution elements. In an embodiment, the frame structure includes a frame having one or more conductive layers sandwiched between non-conductive layers. The frame may, for example, be a printed wire board (PWB) having power planes that distribute power from a first substrate (e.g., a system PWB) and/or a power cable to a second substrate (e.g., an electronic module). The frame includes one or more apertures configured to receive an LGA interposer for electrically connecting the two substrates. Preferably, the frame includes four apertures arranged in quadrants that each receive an interposer, and at least one power plane extends between two quadrants and/or adjacent to a peripheral edge of one or more quadrants in the form of stacked and/or parallel bus bars each defining a power domain. | 10-02-2008 |
| 20080259572 | Mounting a Heat Sink in Thermal Contact with an Electronic Component - A heat transfer apparatus comprises a load frame having load springs and an open region that exposes an electronic component. The load frame is mounted to a printed circuit board on which the electronic component is mounted. A heat sink assembly is disposed on the load frame and has a main body in thermal contact with the electronic component through a thermally conductive material. The heat sink assembly has load arms for engaging the load springs. A load plate extends between the load arms and has an actuation element operative to displace the main body relative to the load plate and thereby resiliently deform the load springs and produce a load force that compresses the thermally conductive material to achieve a desired thermal interface gap between the main body and the electronic component. Non-influencing fasteners secure the heat sink to the load frame and maintain the desired thermal interface gap. | 10-23-2008 |
