The URS retention transfers load to the server board through the unified backplate assembly.
The URS spring, captive in the heatsink, provides the necessary compressive load for the
thermal interface material. All components of the URS heatsink solution are captive to the
heatsink and only require a Philips* screwdriver to attach to the unified backplate assembly.
See the following figure for the stacking order of the URS components.
