Thermally
Conductive Adhesive
Transfer Tapes
This range of high adhesion thin tapes offers efficient thermal transfer for a wide range of applications
requiring a thermal management solution: bonding heat sinks, heat spreaders and other cooling
devices to IC packages, power transistors, and other heat generating components.
Each tape combines 3M high performance acrylic adhesive with highly conductive ceramic particles
for an extremely reliable and user-friendly thermal interface. Highly conformable construction provides
excellent wet-out on surfaces.
Select 5, 10, 15 and 20 mil thicknesses to meet application requirements.
