The recommended attachment method to the heat sink is illustrated in Figure 73. The heat sink should be attached to the
printed-circuit board with the spring force centered over the die. This spring force should not exceed 10 pounds force (45
Newton).
Figure 73. Package Exploded Cross-Sectional View with Several Heat Sink Options
The system board designer can choose between several types of heat sinks to place on the device. Ultimately, the final selection
of an appropriate heat sink depends on many factors, such as thermal performance at a given air velocity, spatial volume, mass,
attachment method, assembly, and cost. Several heat sinks offered by Aavid Thermalloy, Advanced Thermal Solutions, Alpha
Novatech, IERC, Chip Coolers, Millennium Electronics, and Wakefield Engineering offer different heat sink-to-ambient
thermal resistances, that will allow the MPC8536E to function in various environments.
2.24.3.1
Internal Package Conduction Resistance
For the packaging technology, shown in Table 70, the intrinsic internal conduction thermal resistance paths are as follows:
The die junction-to-case thermal resistance
The die junction-to-board thermal resistance
Figure 74 depicts the primary heat transfer path for a package with an attached heat sink mounted to a printed-circuit board.
