Mechanical Specifications
The Quad-Core Intel® Xeon® Processor 5400 Series is packaged in a Flip Chip Land
Grid Array (FC-LGA) package that interfaces to the baseboard via a LGA771 socket. The
package consists of a processor core mounted on a pinless substrate with 771 lands. An
integrated heat spreader (IHS) is attached to the package substrate and core and
serves as the interface for processor component thermal solutions such as a heatsink.
Figure 3-1
shows a sketch of the processor package components and how they are
assembled together. Refer to the LGA771 Socket Design Guidelines for complete details
on the LGA771 socket.
The package components shown in
Figure 3-1
include the following:
• Integrated Heat Spreader (IHS)
• Thermal Interface Material (TIM)
• Processor Core (die)
• Package Substrate
• Landside capacitors
• Package Lands

Package Mechanical Drawings
The package mechanical drawings are shown in
Figure 3-2
through
Figure 3-4
. The
drawings include dimensions necessary to design a thermal solution for the processor
including:
• Package reference and tolerance dimensions (total height, length, width, and so
forth)
• IHS parallelism and tilt
• Land dimensions
• Top-side and back-side component keepout dimensions
• Reference datums
Note:
All drawing dimensions are in mm [in.].
