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.
1.8.9.1 Internal Package Conduction Resistance
For the exposed-die packaging technology, shown in Table 3, 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 25 depicts the primary heat transfer path for a package with an attached heat sink mounted to a
printed-circuit board.
Figure 25. C4 Package with 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.
