Product Description
3M^TM Thermally Conductive Adhesive Tapes 8940 / 8943 are
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^TM 8943) or both sides (3M^TM
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.

The film liner is a double sided siliconized Polyester Film with a
differential release system.
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.
