Socket A. This processor utilizes the Organic Pin Grid Array 
(OPGA) package type described in this chapter. For more

9.1
Die Loading
The processor die on the OPGA package is exposed at the top of 
the package. This feature facilitates heat transfer from the die 
to an approved heat sink. Any heat sink design should avoid 
loads on corners and edges of die. The OPGA package has 
compliant pads that serve to bring surfaces in planar contact. 
Tool-assisted zero insertion force sockets should be designed so 
that no load is placed on the ceramic substrate of the package.
Table 16 shows the mechanical loading specifications for the 
processor die. It is critical that the mechanical loading of the 
heat sink does not exceed the limits shown in Table 16.
