摘要: A processor-inclusive memory module (PIMM) is disclosed. In one embodiment of the present invention, the PIMM includes a printed circuit board having first and second opposing surfaces. The printed circuit board also has an address line formed therein. A first SRAM is mounted on the first surface of the printed circuit board. The present PIMM is further comprised of a second SRAM mounted on the second surface of the printed circuit board. The second SRAM is mounted on the second surface of the printed circuit board directly opposite the first SRAM mounted on the first surface of the printed circuit board. The first and second SRAMs are coupled to the address line by respective cache buses. A processor is also mounted on the first surface of the printed circuit board, and is coupled to the address line. In one embodiment of the invention, a heat sink is thermally coupled to the processor. The processor has a plurality of contact pads disposed thereon. Electrical connectors extend from the second surface of the printed circuit board. The electrical connectors are electrically coupled to respective contact pads of the processor. In the present PIMM, the electrical connectors are adapted to be removably attached to a mother board. In so doing, the present PIMM is removably attachable to a mother board.

摘要: A support is provided for a component on a substrate to minimize unacceptable bending or displacement. In a preferred embodiment, a suitable amount of a thermoplastic material is injected through a hole in a PCB under the component after the component has been affixed to the PCB. This allows the support material to fill any space between the component and the PCB yet allow for variation in lead height and for thermal expansion of the support material.

摘要: A unitary heat sink including a planar contact portion for contacting the top of an IC. The heat sink is constructed from a material having a thermal conductivity of at least 150 watts per meter Degree Kelvin (W/m.degree.K.) but preferably is constructed from aluminum having a conductivity of 221 (W/m.degree.K.). A number of leg portions extend from the contact portion such that each leg portion has a distal end. The leg portions, being made of the same material as the contact portion, are configured to have a sufficient resiliency such that deformations of the leg portions provide a spring force in the range of 5 to 16 lbs against the top of the IC. A method for dissipating heat from an integrated circuit includes the steps of forming a unitary heat sink from a heat sink material, where the heat sink includes a contact portion and a number of integral, spring leg portions. The method continues with the attachment of an integrated circuit to a printed circuit board, and the attachment of the leg portions of the heat sink to the printed circuit board such that the contact portion of the heat sink is urged towards the heat transfer surface of the integrated circuit with a spring force in the range of 5 to 16 lbs.

摘要: A mobile home jack and coupler assembly is adapted for mounting to the A-frame or tongue of a mobile home. Both top mounted coupler assembly and inverted bottom mounted coupler assembly are disclosed. Each includes a screw jack which mounts from underneath. The screw jack carries, adjacent its lower end, a mounting plate which is received in underlying relation to a portion of the coupler, while the upper end thereof extends through a guide plate above the coupler. The mounting plate on the jack is welded to the jack body by an underlying weld, with the result that the tongue weight of the mobile home is carried directly by the jack support plate in compression, rather than in tension, and the compressive force is transferred by the underlying weld, also in compression, to the jack body. As a result, jack mounting screws do not carry the tongue weight applied to the jack, and greater tongue loads can more safely be carried.

摘要: An offset spindle and spindle support for a mobile home axle is disclosed, in which the wheel spindle is vertically offset with respect to a conventional axle tube. The offset support comprises a generally cup-shaped stamping and utilizes the backing plate of the brake to form a box-section, low-cost high strength offset support for a forged wheel spindle.
