CLIPWATT ASSEMBLING SUGGESTIONS

The suggested mounting method of Clipwatt on external heat sink, requires the use of a clip placed as much

as possible in the plastic body center, as indicated in the example of figure 11.

A thermal grease can be used in order to reduce the additional thermal resistance of the contact between pack-

age and heatsink.

A pressing force of 7 - 10 Kg gives a good contact and the clip must be designed in order to avoid a maximum

contact pressure of 15 Kg/mm2 between it and the plastic body case.

As example , if a 15Kg force is applied by the clip on the package , the clip must have a contact area of 1mm2

at least.
