Mechanical Specifications

Dual-Core Intel® Xeon® Processor 5000 Series Datasheet

10. R is defined as the radial distance from the center of the LGA771 socket ball array to the center of heatsink

load reaction point closest to the socket.

11. Applies to populated sockets in fully populated and partially populated socket configurations.

12. Through life or product. Condition must be satisfied at the beginning of life and at the end of life.

13. Rigid back is not allowed. The board should flex in the enabled configuration.

Package Handling Guidelines

Table 3-2 includes a list of guidelines on a 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.

Notes:

A shear load is defined as a load applied to the IHS in a direction parallel to the IHS top surface.

A tensile load is defined as a pulling load applied to the IHS in a direction normal to the IHS surface.

A torque load is defined as a twisting load applied to the IHS in an axis of rotation normal to the IHS top

surface.

These guidelines are based on limited testing for design characterization and incidental applications (one

time only).

Handling guidelines are for the package only and do not include the limits of the processor socket.

3.5

Package Insertion Specifications

The Dual-Core Intel Xeon Processor 5000 Series can be inserted and removed 15 times

from an LGA771 socket.

3.6

Processor Mass Specifications

The typical mass of the Dual-Core Intel Xeon Processor 5000 series is 21.5 grams [0.76

oz.]. This includes all components which make up the entire processor product.

3.7

Processor Materials
