System Design Information
1.8.9 Thermal Management Information
This section provides thermal management information for the ceramic ball grid array (CBGA) package for
air-cooled applications. Proper thermal control design is primarily dependent upon the system-level
design—the heat sink, airflow, and thermal interface material. To reduce the die-junction temperature, heat
sinks may be attached to the package by several methods—adhesive, spring clip to holes in the
printed-circuit board or package, and mounting clip and screw assembly; see Figure 24. This spring force
should not exceed 5.5 pounds of force. Note that care should be taken to avoid focused forces being applied
to die corners and/or edges when mounting heatsinks.

The board designer can choose between several types of heat sinks to place on the MPC7410. There are
several commercially-available heat sinks for the MPC7410 provided by the following vendors:
