Product Description

3M

designed to provide an efficient heat transfer path between heat

generating components and heat sinks or other cooling devices.

The tapes consist of a carrier, highly loaded with thermally conductive

fillers, coated on either one side (3M

8940) with a high temperature resistance acrylic pressure sensitive

adhesive.

The specialized construction securely bonds the heat generating

components to heat sinks and offer both, good thermal conductivity

and excellent electrical insulation properties.

Typical Applications

Applications requiring good thermal transfer and thin bonding.

Typical applications are assembling of power devices as bare dies in

chip on board technique or flip chip assemblies with a directly

mounted heat sink.

The tape performance properties have been primarily adapted to fit

thermal requirements in applications such as Engine Control Units

bonding, ABS Systems, High power LED’s, and other electronic

increased power devices.
