Ultimately, the nal 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.
1.8.6.1 Internal Package Conduction Resistance
For this packaging technology the intrinsic thermal conduction resistance (shown in Table 3) versus the
external thermal resistance paths are shown in Figure 13 for a package with an attached heat sink mounted
to a printed-circuit board.
