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 71, 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 62 depicts the primary heat transfer path for a package with an attached heat sink mounted to a
printed-circuit board.
Figure 62. Package with Heat Sink Mounted to a Printed-Circuit Board
The heat sink removes most of the heat from the device. Heat generated on the active side of the chip is
conducted through the silicon and through the heat sink attach material (or thermal interface material), and
finally to the heat sink. The junction-to-case thermal resistance is low enough that the heat sink attach
material and heat sink thermal resistance are the dominant terms.
