IBM offers a plastic ball grid array, PBGA, which supports 256 balls as the PowerPC 750CX package.
The following sections contain several views of the package, pin information, and a pin listing.
Figure 11 shows the pinout of the 256 PBGA package as viewed from the solder ball surface. Figure 12 shows the side
profile of the 256 PBGA package including the height from the top of the copper heat spreader to the bottom of the sol-
der balls. Figure 13 provides a more detailed side profile including the encapsulant (glob) referenced.
