1.8.6 Thermal Management Information
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 upon the system-level
designthe heat sink, airow and thermal interface material. To reduce the die-junction temperature, heat
sinks may be attached to the package by several methodsadhesive, spring clip to holes in the printed-
circuit board or package, and mounting clip and screw assembly; see Figure 12. This spring force should
not exceed 5.5 pounds of force.

The board designer can choose between several types of heat sinks to place on the 604e. There are several
commercially-available heat sinks for the 604e provided by the following vendors:

Ultimately, the nal selection of an appropriate heat sink for the 604e depends on many factors, such as
thermal performance at a given air velocity, spatial volume, mass, attachment method, assembly, and cost.
