Technical Data | April 2019 3M™ Thermally Conductive Acrylic Interface Pad 5570N Product Description 3M™ Thermally Conductive Acrylic Interface Pad 5570N is designed to provide a preferential heat transfer path between heat generating components like integrated circuit chips (IC) or electric vehicle (EV) batteries and heat spreaders. 3M™ Thermally Conductive Acrylic Interface Pad 5570N consists of a highly conformable, slightly tacky acrylic elastomer sheet filled with thermally conductive ceramic particles which provide special features listed as follows. Key Features and Benefits • • • • • Easy handling and soft Highly conformability even for non-flat integrated circuit (IC) surfaces and automotive batteries Good thermal conductivity while being electrically insulating Slight tack allows pre-assembly. Good wettability for better thermal conductivity No siloxane gas/oil bleeding, which can cause electric connection failure Product Construction/Material Description PET liner Thermally conductive conformable layer PET liner 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 Acrylic Interface Pad 5570N Property Value Color White with light gray dots Base resin Acrylic Pad Thickness 0.5, 1.0, 1.5, 2.0 mm (thicker pads available upon request) Primary Filler Type Ceramic Product Liner PET Film Roll Length Standard: 33 M Custom size can be supplied by user requests. Applications • Heat transfer in consumer electronics and automotive electronics • Decrease of compression stress to electronic parts by thermal pad softness Examples: o Heat transfer between PCB and heat sink o Thermal management electric vehicle/hybrid battery for automotive o Power electronics component thermal management 3M™ Thermally Conductive Acrylic Interface Pad 5570N o o o o Chip on film (COF) heat conduction LED thermal management HDTV IC chip General gap filling in electronic device Application Techniques • • • • Substrate surfaces should be clean and dry prior to pad application. Isopropyl alcohol (isopropanol) applied with a lint free wipe or swab should be adequate for removing surface contamination such as dust or finger prints. Do not use “denatured alcohol” or glass cleaners which often contain oily components. Allow the surface to dry for several minutes before applying the pad. More aggressive solvents (such as acetone, methyl ethyl ketone (MEK) or toluene) may be required to remove heavier contamination (grease, machine oils, solder flux, etc.) but should be followed by a final isopropanol wipe as described above. Be sure to read and follow the manufacturers’ precautions and directions when using primers and 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 application. Ideal application temperature range is from 15°C to 40°C. Initial application to surfaces at temperatures below 10°C is not recommended because the pad becomes too firm to be wetted readily. However, once properly applied, low temperature performance is generally satisfactory.
