Reference Thermal Solutions—Core™ 2 Duo Mobile Processors

6.5.1Keep Out Zone Requirements

The keep out zone requirements on the PCB to use this heatsink are detailed in Appendix B, “Mechanical Drawings.” Because it extends beyond the footprint of the device, it is critical for board designers to allocate space for the heatsink.

6.5.2Thermal Performance

The cPCI reference heatsink is an all copper (C1100) design, intended for applications where vertical space is limited. The heatsink has been tested at flow rates from 4 CFM to 24 CFM. For a 40 °C external ambient and 17W TDP, the heatsink is expected to meet the thermal performance needed when the air flow rate is at least 4 CFM.

6.6Heatsink Fastener Assembly

The reference solutions use a screw, spring, and back plate assembly to attach the heatsink to the PCB. The fastener assembly used on the reference heatsink must apply the load conditions described in Section 4.1, “Package Mechanical Requirements” . The fastener assembly must comply with all of the keep out zone requirements described in this document, and should not degrade the thermal performance of the reference heatsinks. Finally the fastener assembly should be designed to meet the reliability guidelines described in Section 8.0, “Reliability Guidelines” .

6.7Thermal Interface Material (TIM)

The thermal interface material provides improved conductivity between the die and heatsink. It is important to understand and consider the impact of the interface between the die and heatsink base to the overall thermal solution. Specifically, the bond line thickness, interface material area, and interface material thermal conductivity must be selected to optimize the thermal solution.

It is important to minimize the thickness of the thermal interface material (TIM), commonly referred to as the bond line thickness. A large gap between the heatsink base and the die yields a greater thermal resistance. The thickness of the gap is determined by the flatness of both the heatsink base and the die, plus the thickness of the thermal interface material, and the clamping force applied by the heatsink attachment method. To ensure proper and consistent thermal performance, the TIM and application process must be properly designed.
