Thermal/Mechanical Specifications and Design Guide 17
Package Mechanical Specifications
2.1.3 Package Loading Specifications
Ta b l e 2 - 1 provides load specifications for the processor package. These maximum
limits should not be exceeded during heatsink assembly, shipping conditions, or
standard use condition. Exceeding these limits during test may result in component
failure. The processor substrate should not be used as a mechanical reference or load-
bearing surface for thermal solutions.
.
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 Independent Loading Mechanism
(ILM).
3. These specifications are based on limited testing for design characterization. Loading limits are for the
package constrained by the limits of the processor socket.
4. Dynamic loading is defined the maximum heatsink mass from Tab l e 5-3 with an 11 ms duration average
load superimposed on the static load requirement.
5. See Section 5.3 for minimum socket load to engage processor within socket.
2.1.4 Package Handling Guidelines
Ta b l e 2 - 2 includes a list of guidelines on package handling in terms of recommended
maximum loading on the processor IHS relative to a fixed substrate. These package
handling loads may be experienced during heatsink removal.
2.1.5 Package Insertion Specifications
The processor can be inserted into and removed from an LGA2011-0 socket 15 times.
The socket should meet the LGA2011-0 requirements detailed in Chapter 3 and
Chapter 5.
2.1.6 Processor Mass Specification
The typical mass of the processor is currently 45 grams. This mass [weight] includes all
the components that are included in the package.
