Thermal Management Information
This section provides thermal management information for the CBGA package for air cooled applications.
Proper thermal control design is primarily dependent upon the system-level design; that is, the heat sink, air
flow, and the 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 20.
