Information
This section provides thermal management information for the tape ball grid array
(TBGA) 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 4.
