A method and apparatus for attaching heatsinks having a disproportional size relative to the electronic component to which they are attached. In general, the apparatus comprises variable-length attaching means for attaching each corner of the heatsink to the circuit card while maintaining sufficient contact with the electronic component. The variable-length attaching means includes a post and a receiving well. Both the post and receiving well include attaching means, such as threads and nuts, for attachment to the heatsink and circuit board, respectively. The variable-length attaching means accommodates height variations between parts, establishes high structural integrity after assembly, controls static and dynamic loading of the solder columns, allows for module re-work while re-using the heatsink and card, and provides adequate protection from shock, vibration, and handling.
