Abstract
An apparatus is provided having an integrated circuit device disposed on a printed circuit board and a heat dissipation device on the integrated circuit device. An actuation screw in a spring plate is urged against a portion of the heat dissipation device by tightening the actuation screw. The actuation screw may be prevented from being tightened beyond a mechanical constraint corresponding to a pre-set calibration for the specific compressive force, which may be greater than or equal to a minimum compressive force corresponding to the greater of a minimum thermal interface pressure and a minimum contact interface pressure. Additionally, a method is provided in which the actuation screw is tightened, but prevented from being tightened beyond the mechanical constraint.
