PC8240
2149A–HIREL–05/02
The board designer can choose between several types of heat sinks to place on the
PC8240. There are several commercially-available heat sinks for the PC8240 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.
Internal Package Conduction
Resistance
For the TBGA, cavity down, packaging technology, shown in Figure 4 on page 10, the
intrinsic conduction thermal resistance paths are as follows:
The die junction-to-case thermal resistance,
The die junction-to-ball thermal resistance.
Figure 6 depicts the primary heat transfer path for a package with an attached heat sink
mounted to a printed-circuit board.
Figure 6.
C4 Package with Heat Sink Mounted to a Printed-Circuit Board
For this cavity-down, wire-bond TBGA package, heat generated on the active side of the
chip is conducted through the silicon, the die attach and package spreader, 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.
