E7230 Chipset Memory Controller Hub (MCH)

Thermal/Mechanical Design Guide

Packaging Technology

The Intel E7230 chipset consist of three individual components: the MCH, the ICH7 and the Intel
6700PXH 64-bit PCI Hub. The Intel E7230 chipset MCH components use a 34 mm squared,
6-layer flip chip ball grid array (FC-BGA) package (see

Figure 2-1

Figure 2-2

and

Figure 2-3

). For

information on the Intel 6700PXH 64-bit PCI Hub package, refer to the
