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.
19.2.1
Internal Package Conduction Resistance
For the exposed-die packaging technology described in Table 71, the intrinsic conduction thermal
resistance paths are as follows:
The die junction-to-case thermal resistance (the case is actually the top of the exposed silicon die)
The die junction-to-board thermal resistance
Figure 60 depicts the primary heat transfer path for a package with an attached heat sink mounted to a
printed-circuit board.
Figure 60. 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, through the heat sink attach
material (or thermal interface material), and finally to the heat sink where it is removed by forced-air
convection.
Because the silicon thermal resistance is quite small, the temperature drop in the silicon may be neglected
for a first-order analysis. Thus the thermal interface material and the heat sink conduction/convective
thermal resistances are the dominant terms.
