5.2 Socketable Micro-PGA2 Package Dimensions
The mobile Pentium III processor is also packaged in a PPGA-B495 package (also known as
Micro-PGA2) with the back of the processor die exposed on top. Unlike previous mobile
processors with exposed die, the back of the mobile Pentium III processor die may be polished and
very smooth. The mechanical specifications for the socketable package are provided in Table 29.
Figure 23 shows the top and side views of the socketable package, and Figure 24 shows the
bottom view of the socketable package. The substrate may only be contacted within the region
between the keep-out outline and the edge of the substrate. The mobile Pentium III processor will
have one or two label marks. These label marks will be located along the long edge of the
substrate outside of the keep-out region, and they will not encroach upon the 7-mm by 7-mm
squares at the substrate corners. Unlike the BGA2 package, VID implementation does not require
VID pins to be depopulated on the Micro-PGA2 package.
