High serviceability heatsink retainer method and apparatus

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.
