Surface-mount BGA2 Package Dimensions
The mobile Pentium III processor is packaged in a PBGA-B495 package (also known as BGA2)
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 surface-mount package are provided in Table 28. Figure 21
shows the top and side views of the surface-mount package, and Figure 22 shows the bottom view
of the surface-mount package. The substrate may only be contacted within the shaded 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. Please note that in order to implement VID on the BGA2 package,
some VID[4:0] balls may be depopulated.
