The shape and hole pattern of the heat sink will determine the shape and hole
pattern of the pad. If you are ordering a heat sink which mounts to a semicon-
ductor on both sides, the ordering code for two pads should be used. To order

In-Sil-8
ORDERING INFORMATION
KonDux™ / Grafoil® Conducta-Pad**
Kondux™ interface pads are a cost effective
alternative to thermally conductive grease
compounds. Kondux™ pads are electrically
conductive and ideal for use with small,
discrete semiconductors. Aavid pre-applies
Kondux™ to your heatsink to enhance heat
conductance from the semiconductor case
and speed your manufacturing process.
These silicone based pads provide both thermal
conductivity and electrical isolation. In-Sil-8
pads have a fiberglass carrier that withstands
the rigors of assembly, harsh environments
and aging under continuous use. In-Sil-8
install faster than traditional mica and grease
and will not contaminate solder baths. Screw
mounting is recommended to achieve the best
thermal performance.
