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.
