2.2 Package Loading Specifications
Table 1 provides static load specifications for the chipset package. This mechanical
maximum load limit should not be exceeded during heatsink assembly, shipping
conditions, or standard use conditions. Also, any mechanical system or component
testing should not exceed the maximum limit. The chipset package substrate should
not be used as a mechanical reference or load-bearing surface for the thermal and
mechanical solution.

Parameter Maximum Notes
Static 15 lbf 1,2,3
NOTES:
1. These specifications apply to uniform compressive loading in a direction normal to the
(G)MCH package.
2. This is the maximum force that can be applied by a heatsink retention clip. The clip must
also provide the minimum specified load on the (G)MCH package.
3. These specifications are based on limited testing for design characterization. Loading limits
are for the package only.
