Technical Data April 2019 3M Thermally Conductive Acrylic Interface Pad 5571N and 5571DL Product Description 3M Thermally Conductive Acrylic Interface Pad 5571N and 5571DL are designated to provide a preferential heat transfer path between heat generating components like Integrated Circuit Chip (IC) or electric vehicles (EV) and heat spreaders as aluminum heat sink. 3M Thermally Conductive Acrylic Interface Pad 5571N and 5571DL consist of a highly conformable slightly tacky acrylic elastomeric sheet filled with conductive ceramic particles which provides special features listed as follows Key Features Good softness Highly conformability even to non-flat IC surfaces and automotive batteries Highly thermally conductive while being electrically insulating Slight tack allows easy pre-assembly. Good wettability for better thermal conductivity No siloxane gas/ oil bleeding, which can cause electric connection failure. Good flame retardancy, UL94 V2 rated, File E239181 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 5571N and 5571DL Property Value Color White Base resin Acrylic Pad Thickness 0.5mm Primary Filler Type Ceramic PET Film Product Liner 5571N: Single Liner 5571DL: Double Liner Standard: 33 MT Roll Length Custom size can be supplied by user requests. Applications IC Packaging Heat Conduction Heat Sink COF Chip Heat Conduction LED Board TIM HD TV Address IC Chip and Scan Module Board General Gap Filling in Electronic Device Mechanical fastening such as clamp, bracket, and screw can be used in parallel with this thermal conductive pad. Application Techniques To obtain optimum thermal conductivity, the wetting surfaces must be maximized. For better contact, clean, dry and well unified surface condition is recommended. Typical surface cleaning solvents are isopropyl alcohol and water (rubbing alcohol) or heptane. Note: Be sure to follow manufacturers safety precautions and directions for use when using solvents. Ideal application temperature range is from 15C to 40C. Initial application to surfaces at temperatures below 10C is not recommended because the pad becomes too firm to be wetted readily. However, once properly applied, low temperature holding is generally satisfactory Typical Physical Properties and Performance Characteristics 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 5571N and 5571DL Property Method Typical Value Thickness (mm) - 0.5 b Thermal conductivity (W/m-K) ASTM C1113 2.0 Thermal conductivity (W/m-K) ASTM D5470 1.5 Hardness (Shore 00) ASTM D2240 70 3 Density (grams/cm ) ASTM D6111 1.85 Flammability UL94 V-2 Dielectric Strength (kV/mm) ASTM D149 13 12 Volume Resistivity (-cm) ASTM D257 3.3 x 10 a Methods listed as ASTM are tested in accordance with the ASTM method noted b Thermal Conductivity Test Method: 2.0W/m-K in XY direction per Hot wire plane Test method Heat Resistance 3M Thermally Conductive Acrylic Interface Pad 5571N and 5571DL Duration (hrs) Initial 1000 2000 5000 Thermal Conductivity (W/m-K) 2.0 2.0 2.0 2.0 Hardness (Shore 00) 69 70 70 70 Appearance - No effect No effect No effect *Note 1: Aged by dwelling at 110C high temperature chamber. *Note 2: The end use customer application, design & verification testing will determine the final in use effective temperature range based on each applications environmental conditions.
