Term Definition
FC-BGA
Flip Chip Ball Grid Array. A package type defined by a plastic substrate where
a die is mounted using an underfill C4 (Controlled Collapse Chip Connection)
attach style. The primary electrical interface is an array of solder balls
attached to the substrate opposite the die.
Note: The device arrives at the customer with solder balls attached.
BLT
Bond line thickness. Final settled thickness of the thermal interface material
after installation of heatsink.
ICH9 I/O Controller Hub 9
IHS Integrated Heat Spreader
MCH
Memory controller hub. The chipset component that contains the processor
interface, the memory interface, the PCI Express* interface and the ESI
interface.
T
case_max
Maximum allowed component temperature. This temperature is measured at
the geometric center of the top of the package IHS.
T
case_min
Minimum allowed component temperature. This temperature is measured at
the geometric center of the top of the package IHS.
TDP
Thermal design power. Thermal solutions should be designed to dissipate
this target power level. TDP is not the maximum power that the chipset can
dissipate.
TIM Thermal Interface Material
Ψ
CA
Case-to-ambient thermal characterization parameter. A measure of the
thermal solution thermal performance including TIM using the thermal
design power. Defined as (T
