Thermal Management

Information

This section provides thermal management information for the ceramic ball grid array

(BGA) package for air-cooled applications. 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, and mounting clip and screw assembly; see Figure 7. This spring force should

not exceed 5.5 pounds of force.

Ultimately, the final selection of an appropriate heat sink depends on many factors, such

as thermal performance at a given air velocity, spatial volume, mass, attachment

method, assembly, and cost.
