2.1.3

Package Loading Specifications

Table 2-1
These mechanical maximum load limits should not be exceeded during heatsink
assembly, shipping conditions, or standard use condition. Also, any mechanical system
or component testing should not exceed the maximum limits. The processor package
substrate should not be used as a mechanical reference or load-bearing surface for
thermal and mechanical solution.
.
Table 2-1.

Processor Loading Specifications

Static Compressive Load
Dynamic Compressive Load
Notes:
1. These specifications apply to uniform compressive loading in a direction normal to the processor IHS.
2. This is the maximum static force that can be applied by the heatsink and retention solution to maintain the
heatsink and processor interface.
3. These specifications are based on limited testing for design characterization. Loading limits are for the
package only and do not include the limits of the processor socket.
4. Dynamic loading is defined as an 50g shock load, 2X Dynamic Acceleration Factor with a 500g maximum
thermal solution.

Package Handling Guidelines

maximum loading on the processor IHS relative to a fixed substrate. These package
handling loads may be experienced during heatsink removal.
Table 2-2.

Package Handling Guidelines

Notes:
1. A shear load is defined as a load applied to the IHS in a direction parallel to the IHS top surface.
2. A tensile load is defined as a pulling load applied to the IHS in a direction normal to the IHS surface.
3. A torque load is defined as a twisting load applied to the IHS in an axis of rotation normal to the IHS top
surface.
4. These guidelines are based on limited testing for design characterization.
2.1.5

Package Insertion Specifications

The processor can be inserted into and removed from an LGA1155 socket 15 times. The
socket should meet the LGA1155 socket requirements detailed in
2.1.6

Processor Mass Specification

The typical mass of the processor is 21.5g (0.76 oz). This mass [weight] includes all
the components that are included in the package.
