Thermal Management Solutions for LED Assembly More Light Less Heat High performance cooling - for a new generation of high-intensity LEDs 3M Thermal Management Solutions for LED Assembly TM An emerging need for thermal management Cooling off an an LED LED Cooling Off LED Heat-spreading layer, mechanical support, power supply routing surface or heat sink Base Thermal Interface Tape Durability of interface: Especially in external applications of LEDs, durability of the thermal interface is important to support efficiency in different environmental conditions. 3M products have shown excellent durability through accelerated aging tests. Today's high intensity LEDs are opening up new opportunities for cost savings and reduced power consumption; however, they also generate more heat than conventional LEDs. It's important to remember that the higher the temperature at which LEDs operate, the less efficient they become - making improved thermal management essential for optimal performance. That's where 3M can help. 3M Thermal Interface Materials provide efficient thermal transfer for long-term reliability and performance optimization in applications using high brightness LEDs. 3M Thermal Interface Materials have a proven track record of durability and high thermal performance in a variety of environmental conditions to meet the demanding needs of applications today and in the future. 3M provides a full selection of products to meet customers' process and performance requirements, including thermally conductive pads, adhesives, and greases. TM 3M Thermal Interface Materials TM Product Advanced designs drive need for more efficient cooling *H igh speed/multi-function components More heat generated 3M Thermally Conductive Interface Pads TM Initial development 1970 - 1990: LEDs used as indicator lights 1990s LED technology used as direct light 2000s Higher-power LEDs commercialized, creating the need for thermal management Acrylic pads, 0.5 mm and thicker. Note: 5589H is not available for 0.5 mm. Features High thermal conductivity Excellent gap filling Die cut to size and shape No Silicone oil breeding/contamination Higher thermal conductivity (3 W/m-K) Thin thickness (0.2 mm - 0.25 mm) S version: One side is laminated with thin film for better handling and converting 3M Thermally Conductive Interface Tapes 8904-02 8904-025 8904-05 Acrylic adhesive tapes with thin PET carrier Higher thermal conductivity (1.5 W/m-K) Reworkable UL 94 V-0 3M Thermally Conductive Interface Tapes 8805 8815 Acrylic double-sided tapes, 0.5 mm and thinner High adhesion Die cut to size and shape Excellent wet-out Epoxy adhesives Ultra-thin bond line Higher thermal conductivity than tape Higher shear, peel strength than tape TM 1960s 5570 (1.3 W/m-K) 5589H (Softer) 5590H (Higher thermal conductivity) Description 5515-20 Silicone pad, thin 5515-25 and higher K (S version is also available) * S maller enclosures No room for heat to dissipate The evolution of LED technology 3M ID # TM 8810 8820 3M Thermally Conductive Epoxy TC-2810 TC-2707 Adhesives TM Note: For applications using a thermal pad, the 3M Acrylic Thermal pads are slightly tacky on one side for generally acceptable assembly adhesion in many applications. If higher adhesion is desired, 3M suggests the testing of the 3M Acrylic Adhesive Transfer Tape 9461. TM The tack adhesion strength of the 3M Thermal Pads is sufficient for holding the product in place for assembly and use, etc. in many applications. The end use design of the LED Structure/Thermal Pad/Heat Sink does require an added mechanical means of assembly to ensure long term mechanical integrity and thermal performance. 3M also offers a line of silicone based thermal pads ranging in thermal conductivity from 1.0 W/m-K to 4.9 W/m-K. Please contact 3M for additional product information and inquire about 3M Thermally Conductive Interface Pads 5591(S),5592(S),5595(S),5516(S) and 5519(S).
