Heat Sink Attachment
When heat sinks are attached, an interface material is required, preferably thermal grease and a spring clip.
The spring clip should connect to the printed-circuit board, either to the board itself, to hooks soldered to
the board, or to a plastic stiffener. Avoid attachment forces that can lift the edge of the package or peel the
package from the board. Such peeling forces reduce the solder joint lifetime of the package. The
recommended maximum force on the top of the package is 10 lb force (4.5 kg force). Any adhesive
attachment should attach to painted or plastic surfaces, and its performance should be verified under the
application requirements.
20.3.1
Experimental Determination of the Junction Temperature with a
Heat Sink
When a heat sink is used, the junction temperature is determined from a thermocouple inserted at the
interface between the case of the package and the interface material. A clearance slot or hole is normally
