3M Thermally Conductive Adhesive Transfer Tape 9890 is a 10.0 mil tape designed to provide a preferential heat transfer path between heat generating components and heat sinks or other cooling devices (e.g., fans, heat spreaders or heat pipes).These tapes are pressure sensitive adhesives loaded with thermally conductive ceramic fillers. Pressure is needed to form a bond. Heat and pressure may be needed on some substrates to achieve an acceptable bond. The specialized acrylic chemistry of these tapes provide for good thermal stability of the base polymer. The thermally conductive tapes are on a silicone treated polyester release liner for ease of handling and die cutting. The tapes offer both good thermal conductivity and good electrical insulation properties.
