Processor Package

The processors covered in the document are packaged in a 775-Land LGA package
that interfaces with the motherboard via a LGA775 socket. Refer to the datasheet for
detailed mechanical specifications.
The processor connects to the motherboard through a land grid array (LGA) surface
mount socket. The socket contains 775 contacts arrayed about a cavity in the center
of the socket with solder balls for surface mounting to the motherboard. The socket is
named LGA775 socket. A description of the socket can be found in the LGA775 Socket
Mechanical Design Guide.
The package includes an integrated heat spreader (IHS) that is shown in Figure 2-1
for illustration only. Refer to the processor datasheet for further information. In case
of conflict, the package dimensions in the processor datasheet supersedes dimensions
provided in this document.
