In-Sil-8

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

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-SilTM 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.

No pads

One In-Sil-8TM pad

Two In-Sil-8TM pads

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-
