|
|
| Bond line thickness. Final settled thickness of the |
| BLT | thermal interface material after installation of |
|
| heatsink. |
|
|
|
|
| Flip Chip Ball Grid Array. A ball grid array packaging |
| FCBGA | technology where the die is exposed on the package |
|
| substrate. |
|
|
|
|
| The chipset component that integrates an Ultra ATA |
|
| 100 controller, six Serial ATA host controller ports, |
|
| one EHCI host controller supporting eight external |
| Intel® 6321ESB I/O Controller Hub | USB 2.0 ports, LPC interface controller, flash BIOS |
| interface controller, | |
|
| |
|
| PCI Express interface, BMC controller, Azalia / AC'97 |
|
| digital controller, integrated LAN controller, an ASF |
|
| controller and a ESI for communication with the MCH. |
|
|
|
|
| Linear Feet Per Minute. A measure of airflow emitted |
| LFM | from a forced convection device, such as an axial fan |
|
| or blower. |
|
|
|
|
| Memory controller hub. The chipset component that |
| MCH | contains the processor interface, the memory |
|
| interface, and the South Bridge Interface. |
|
|
|
|
| Maximum die temperature allowed. This temperature |
| is measured at the geometric center of the top of the | |
|
| package die. |
|
|
|
|
| Minimum die temperature allowed. This temperature |
| is measured at the geometric center of the top of the | |
|
| package die. |
|
|
|
|
| Thermal Design Power. Thermal solutions should be |
| TDP | designed to dissipate this target power level. TDP is |
| not the maximum power that the chipset can | |
|
| |
|
| dissipate. |
|
|
|
|
| |
|
| A measure of the thermal solution thermal |
|
| performance including the TIM using total package |
| ΨCA | power. Defined as (TCASE – TLA) / Total Package |
|
| Power. |
|
| Note: Heat source must be specified when using Ψ |
|
| calculations. |
|
|
|
|
| |
|
| measure of the thermal interface material |
| ΨCS | performance using total package power. Defined as |
| (TCASE - TSINK)/ Total Package Power. | |
|
| Note: Heat source must be specified when using Ψ |
|
| calculations. |
|
|
|
|
| |
|
| A measure of the heat sink performance using total |
| ΨSA | package power. Defined as (TSINK - TLA)/Total |
| Package Power. | |
|
| Note: Heat source must be specified when using Ψ |
|
| calculations. |
