Technical Data September 2016 3M Thermally Conductive Silicone Interface Pad 5584 Product Description 3M Thermally Conductive Silicone Interface Pad 5584 is designed to provide a preferential heat transfer path between heat generating components and heat sinks, heat spreaders or other cooling devices. 3M pad 5584 consists of a highly conformable and slightly tacky silicone elastomeric sheet filled with thermally conductive ceramic particles that provide enhanced thermal conductivity and excellent electrical insulation performance. Key Features Good softness and conformability even to non-flat surfaces Good thermal conductivity Good electrical insulation properties Compression relaxation properties helps reduce pressure to electric components Slight tack allows pre-assembly Good wettability for improved and lower thermal resistance Product Construction/Material Description Note: The following technical information and data should be considered representative or typical only and should not be used for specification purposes. 3M Thermally Conductive Silicone Interface Pad 5584 Property Value Color White Base resin Silicone Thickness 0.5 - 2.0 mm* Primary filler Ceramic Product liner PET Film Liners * Standard thickness range. Custom thickness options available up to 10 mm. Contact your local 3M Technical Representative for more information.

A clean surface can improve the thermal performance of an application. Isopropyl alcohol (isopropanol) applied with a lint-free wipe or swab should be adequate for removing surface contamination such as dust or fingerprints. Do not use denatured alcohol or glass cleaners, which often contain oily components. Allow the surface to dry for several minutes before applying the thermal pad. More aggressive solvents (such as acetone, methyl ethyl ketone (MEK) or toluene) may be required to remove heavier contamination (such as grease, machine oils, solder flux) but should be followed by a final isopropanol wipe as described above. Note: Be sure to read and follow the manufacturers precautions and directions when using solvents. Apply the thermal pad to one substrate at a modest angle with the use of a squeegee, rubber roller or finger pressure to help reduce the potential for air entrapment under the thermal pad during its application. Remove the release liner before application. Assemble the part by applying compression to the substrates to ensure a good wetting of the substrate surfaces with the thermal pads. Rigid substrates are more difficult to assemble without air entrapment as most rigid parts are not flat. Flexible substrates can be assembled to rigid or flexible parts with much less concern about air entrapment because one of the flexible substrate can conform to the other substrates during application.
