Thermally conductive adhesive tapes are usually transfer adhesives or double-coated tapes.  (Interested in learning more about tape constructions?  Click here.)  Adhesive types include thermally conductive acrylic and silicone, which png-electronics-page-2are often coated to a support substrate like polyimide film, fiberglass and aluminum foil.  The support substrate adds dimensional stability, which provides ease of handling and die cutting. 

The conductive tapes create a path to dissipate heat away from a heat-generating component to a heat sink or other cooling device.   The adhesive creates a better surface contact in the interface joint, reducing thermal resistance and further cooling the device.  The high tack of the adhesive provides a strong bond between the two components, often displacing heavy mechanical attachment.   

Thermally conductive tapes are typically chosen for their mechanical adhesive strength, reliable long-term performance, lightweight and thin profile.  Most also have a UL94 V-0 flammability rating.

These tapes are often used in electronics assemblies and for LED lighting thermal management.
