This section provides thermal management information for the plastic ball grid array (PBGA) package for
air-cooled applications. Depending on the application environment and the operating frequency, a heat
sink may be required to maintain junction temperature within specifications. Proper thermal control design
primarily depends on the system-level design: heat sink, airflow, and thermal interface material. To reduce
the die-junction temperature, heat sinks can be attached to the package by several methods: adhesive,
spring clip to holes in the printed-circuit board or package, or mounting clip and screw assembly (see

A heat sink is not attached to the PBGA package and a high board-level thermal loading from
adjacent components exists (label used—1s).
A heat sink is not attached to the PBGA package and a low board-level thermal loading from
adjacent components exists (label used—2s2p).
A large heat sink (cross cut extrusion, 38 × 38 × 16.5 mm) is attached to the PBGA package and a
high board-level thermal loading from adjacent components exists (label used—1s/sink).
