Abstract
A fixture to facilitate fabrication of a heat sink includes a base plate to support a lower section of the heat sink, and multiple registration pins extending from the base plate. A platen is provided over a heat transfer element (HTE) of the heat sink, with the platen including slip fit regions to slip fit around respective registration pins, and with the lower section and HTE disposed between the base plate and the platen, and forming a fixture stack segment aligned with an active region of the cold plate. A load plate is provided which includes slip fit regions configured to slip fit around corresponding registration pins with the load plate disposed over the fixture stack segment. The load plate includes a single load pin centrally disposed to apply a load to the fixture stack segment and facilitate bonding the lower section and HTE together.
