Abstract: A socket may comprise an array of first contacts and a set of second contacts having a greater conductive cross-sectional area than the first contacts. The set of second contacts may also have a greater conductive area efficiency than the array of first contacts, with conductive area efficiency defined as a total conductive cross-sectional area divided by a total occupied area. The array of first contacts may electrically couple signal pads of a land grid array (LGA) component with a plurality of signal lines in a printed circuit board (PCB). The set of second contacts may electrically couple power delivery land pads of the LGA component with power and ground planes of the PCB.

Abstract: A electronic assembly is disclosed and claimed. The electronic assembly includes a first substrate and a second substrate. A plurality of power connections are coupled between the first substrate and the second substrate and a multiplicity of signal connections separate from the plurality of power connections are also coupled between the first substrate and the second substrate. Each of the plurality of power connections have a substantially different size and shape compared to each of the multiplicity of signal connections.

Abstract: The heat sink is described which is used to cool an electronic component of a computer. The heat sink is constructed from a metal sheet which is bent so as to have a horizontal thermally conductive plate and four walls extending upwardly from the plate and jointly define an enclosure. Openings are formed in the walls through which air can flow by natural convection.

Abstract: Solder bumps are created on a substrate of an electronic assembly having lengths that are longer than the widths. The solder bumps are created by locating solder balls of power or ground connections close to one another so that, upon reflow, the solder balls combine. Signal solder balls however remain separated. Capacitors are created by locating power solder bumps adjacent ground solder bumps and extending parallel to one another.

Abstract: An assembly includes a substrate with mounting apertures. A frame is disposed through the apertures, optionally in a non-core area of the substrate, where a chassis at least partially encompasses a portion of the substrate. A component is coupled with the frame, and the frame is coupled with the chassis.

Abstract: Coupling components to an underlying substrate using a composition of a polymer and magnetic material particles. Upon applying the composition between the component and the printed circuit board, the composition may be subjected to a magnetic field to align the magnetic material particles into a conductive path between the component and the underlying substrate. At the same time the polymer-based material may be cured or otherwise solidified to affix the conductive path formed by the magnetic material particles.

Abstract: A method and apparatus to thermally control multiple electronic components, such as field-effect transistors for voltage regulation in processors and chipsets in computers, allow more effective convective cooling by grouping the electronic components in an at least essentially closed loop configuration about a passageway which is open at both ends to permit air flow therethrough. The electronic components form respective side walls of the passageway or are in heat conducting relation with the side walls of a heat sink which forms the passageway. Mounting the electronic components to stand upright off the motherboard allows air to enter below the components and rise up through the passageway producing an increase in air speed and better convective cooling.

Abstract: A protective coating of insulating material is formed around a clearance hole in a conductive layer of a printed circuit board, so that the conductive material in a via within the clearance hole will not contact the conductive layer and create a short circuit. In one embodiment, the protective coating is sufficiently hard to deflect a drill bit being used to drill the via hole, thus protecting against misregistered drilled holes.

The vapor chamber includes at least one extension on a vapor chamber upper surface which is adapted to direct a condensed working fluid toward a desired location on a vapor chamber lower surface.

Abstract: Piezoelectric wafers are affixed to a circuit card to control displacement of the circuit card when vibrated. A trigger wafer located at an anti-node of the dominant mode shape produces a voltage as a function of modal displacement. A control system responsive to the trigger wafer produces voltages that are applied to flex wafers at a different anti-node of the dominant mode shape. The flex wafers expand and contract in a manner that reduces the modal displacement of the circuit card. Multiple flex wafers can exist, affixed to the circuit card substantially opposite each other, or a single flex wafer can exist with a single trigger wafer. The trigger wafer can be located substantially opposite the flex wafer or can be located elsewhere on the circuit card.
