3.4 Package Handling Guidelines
Table 18 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 heat sink removal.
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 and incidental applications (one
time only).
5. Handling guidelines are for the package only and do not include the limits of the processor socket.
3.5 Package Insertion Specifications
The Low Voltage Intel
®
Xeon™ processor with 800 MHz system bus can be inserted and removed
15 times from an mPGA604 socket, which meets the criteria outlined in the mPGA604 Socket
Design Guidelines.
3.6 Processor Mass Specifications
The typical mass of the Low Voltage Intel
®
Xeon™ processor with 800 MHz system bus is
25 grams [0.88 oz.]. This mass [weight] includes all components which make up the entire
processor product.
3.7 Processor Materials
The Low Voltage Intel
®
Xeon™ processor with 800 MHz system bus is assembled from several
components. The basic material properties are described in Table 19.
