摘要:
Systems and methods of fabricating circuit board assemblies may provide for a circuit board assembly that includes an expansion card having a first side and a second side, a first set of semiconductor packages coupled to the first side and a second set of semiconductor packages coupled to the second side. The circuit board assembly may also include a synergistic combination of cooling solutions for the expansion card such as a metallic duct, centrifugal fan or secondary plate, structural solutions for the expansion card such as a clamp structure or retention interlock, and volume reduction solutions for the expansion card such as one or more flipped power connectors.

摘要:
A computer assembly is described. That computer assembly includes a plate that contains a plurality of receptacles for receiving a plurality of fasteners, and that has a plurality of openings for enabling components to pass through it. The computer assembly also includes a plurality of fasteners, each being coupled to a receptacle, and a printed circuit board. The printed circuit board is attached to the plate by the plurality of fasteners, and a plurality of components pass through the openings formed in the plate.

A method and apparatus for holding a screw captive to a printed circuit board (PCB), with a channel formed through the apparatus and a mounting hole formed through the PCB being in alignment to allow a screw to pass therethrough.
摘要:
A method and an apparatus for releasably retaining a heatsink in contact with an IC attached to a circuitboard in which the heatsink is inserted into a spring cage that is pivotally connected with an actuation lever, wherein at least a pair of spring tabs engage the heatsink to press a thermal conductive surface of the heatsink towards a circuitboard and an IC attached to the circuitboard when the combination of the heatsink, actuation lever and spring cage are inserted into the rectangular frame of a retention module mounted on the circuitboard so as to surround the IC and the lever portion of the actuation lever is pivoted towards the spring cage so as to cause retention points on the actuator portions of the actuation lever and on the rectangular frame of the spring cage to engage corresponding retention points on the rectangular frame of the retention module.
