System Design Information
1.7.6 Thermal Management Information
This section provides thermal management information for the plastic ball grid array (PBGA) package for
air-cooled applications. Proper thermal control design is primarily dependent upon the system-level
designthe heat sink, airow and thermal interface material. Figure 25 depicts the die junction-to-ambient
thermal resistance for two typical cases:
1. A heat sink is not attached to the PBGA package and there exists high board-level thermal loading
of adjacent components. See òTypical Upper Limitó curve in Figure 25.
2. A heat sink is not attached to the PBGA package and there exists low board-level thermal loading
of adjacent components. See òTypical Lower Limitó curve in Figure 25.
Figure 25 shows the die junction-to-ambient resistance.
