In-Sil-8
TM
These silicone based pads provide both thermal
conductivity and electrical isolation. In-Sil-8
TM
pads have a fiberglass carrier that withstands
the rigors of assembly, harsh environments
and aging under continuous use. In-Sil-8
TM
pads
install faster than traditional mica and grease
and will not contaminate solder baths. Screw
mounting is recommended to achieve the best
thermal performance.
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
additional In-Sil
TM
pads separate, or factory applied variations please contact
an Aavid sales rep for inquiries.

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.
