System Design Information
The board designer can choose between several types of heat sinks to place on the MPC755. There are
several commercially-available heat sinks for the MPC755 provided by the following vendors:

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.
8.8.1
Internal Package Conduction Resistance
For the exposed-die packaging technology, shown in Table 4, the intrinsic conduction thermal resistance
paths are as follows:
The die junction-to-case (or top-of-die for exposed silicon) thermal resistance
The die junction-to-ball thermal resistance
Figure 26 depicts the primary heat transfer path for a package with an attached heat sink mounted to a
printed-circuit board.
Heat generated on the active side of the chip is conducted through the silicon, then through the heat sink
attach material (or thermal interface material), and finally to the heat sink where it is removed by forced-air
convection.
Since the silicon thermal resistance is quite small, for a first-order analysis, the temperature drop in the
silicon may be neglected. Thus, the heat sink attach material and the heat sink conduction/convective
thermal resistances are the dominant terms.
