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 on 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—spring clip to holes in the printed-circuit board
or package, and mounting clip and screw assembly (see
mass of the heat sink, attachment through the printed-circuit board is suggested. If a spring clip is used,
the spring force should not exceed 10 pounds.
The board designer can choose between several types of heat sinks to place on the MPC7457. There are
several commercially available heat sinks for the MPC7457 provided by the following vendors:
