Technical Data June 2011 3M™ Thermally Conductive Silicone Interface Pad 5515-20 and 5515-25 Product Description 3M™ Thermally Conductive Silicone Interface Pads 5515-20 and 5515-25 are designed to provide a preferential heat transfer path between heat generating components and heat sinks, heat spreaders or other cooling devices. The 3M Pad 5515 product is the thinnest product among 3M™ Thermally Conductive Silicone Pad products and consists of a highly conformable and slightly tacky silicone elastomeric sheet filled with thermally conductive ceramic particles which provide good thermal performance and with good electrical insulation performance. Product Uses This product can be used as the Thermal Interface Materials (TIM) to improve heat management of electronic devices and joining/stacking parts in electronic component assemblies. Key Features • Thin thickness for lower thermal impedance. • High thermal conductivity. • Good softness and conformability for firm silicone thin pad type. • Good electrical insulation property. • Good pressure relaxation reduces pressure to electric components. • Slight tack allows pre-assembly. • Good wet-ability to a surface for better thermal dissipation. • Fine dimensional stability for easy converting.

(2) 3M™ Thermally Conductive Silicone Interface Pad 5515-20 and 5515-25 Application Technique • Adhesion strength of the 3M™ Thermally Conductive Silicone Interface Pad 5515 is dependent upon the total amount of surface contact developed. Firm application pressure helps develop better contact and improves adhesion strength as the product is slightly tacky only. • Contact surfaces should be clean, dry and well unified to allow for improved adhesion and thermal performance. Typical surface cleaning solvents are an isopropyl alcohol and water blend: Note: Follow manufacturer’s safety precautions and directions for use when using solvents. • Useful application temperature range is from 20°C to 40°C. Initial application to surfaces at temperatures below 20°C is not suggested because the pad will be firmer and wet-out could be reduced. However, once properly applied, low temperature holding is generally satisfactory.
