Thermal Management Information
This section provides thermal management information for the tape ball grid array (TBGA) package for
air-cooled applications. Depending on the application environment and the operating frequency, heat sinks
may be required to maintain junction temperature within specifications. 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, or mounting clip and screw assembly;

Figure 30 depicts the die junction-to-ambient thermal resistance for four typical cases:
A heat sink is not attached to the TBGA package and there exists a high board-level thermal loading
from adjacent components.
A heat sink is not attached to the TBGA package and there exists a low board-level thermal loading
from adjacent components.
A heat sink (for example, ChipCoolers) is attached to the TBGA package and there exists high
board-level thermal loading from adjacent components.
A heat sink (for example, ChipCoolers) is attached to the TBGA package and there exists low
board-level thermal loading from adjacent components.
