BGA

Ball Grid Array. A package type defined by a resin-fiber substrate, onto which a die is 
mounted, bonded and encapsulated in molding compound. The primary electrical interface is 
an array of solder balls attached to the substrate opposite the die and molding compound. 

ICH3-S

I/O Controller Hub. The chipset component that contains the primary PCI interface, LPC 
interface, USB, ATA-100, and other legacy functions.

MBGA

Mini Ball Grid Array. A version of the BGA with a smaller ball pitch.

MCH

Memory Controller Hub. The chipset component that contains the processor interface and 
the memory interface. 

FC-BGA

Flip Chip Ball Grid Array. A packaging technology used for the Intel

chipset MCHs.

P64H2

Bus Controller Hub. The chipset component that interfaces the PCI-X buses.

T

case-nhs

The maximum package case temperature without any package thermal solution. This 
temperature is measured at the geometric center of the top of the package case.

T

die-nhs

The maximum die temperature without any package thermal solution. This temperature is 
measured at the geometric center of the top of the package die.

T

die-hs

The maximum die temperature with the reference thermal solution attached. This 
temperature is measured at the geometric center of the top of the package die.

TDP

Thermal Design Power. Thermal solutions should be designed to dissipate this target power 
level.
