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 MPC8544E to function in various environments.

20.3.1

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
