Thermally Conductive Silicone Interface Pad 5515
Product Description
3M™ Thermally Conductive Silicone Interface Pad 5515 is designed to provide a preferential heat transfer path between
heat generating components and cooling devices for applications with a thin thickness (0.2-0.25 mm) requirement.
Features and Benefits
• Good thermal conductivity (3.0 W/m-K)
• Hardness: Shore 00 = 80
• Good dielectric properties
• UL 94 V-0
• High temperature resistance
• Good converting for complicated shape
• Good flexibility with over bending
• Thin thickness for lower thermal impedance
Product Uses
This product can be used as the Thermal Interface Material (TIM) to help improve heat management of electronic devices
and joining/stacking parts in electronic component assemblies.
Product Construction
3M™ Thermally Conductive Silicone Interface Pad 5515
Removable PET Liner
Thermally Conductive Silicone
Removable PE or PET Film
Standard thickness (excluding liner): 0.20 mm (5515-20), 0.25 mm (5515-25)
Application Ideas
• IC Packaging Thermal Interface Material (TIM)
• Printed Circuit Board Heat Sink TIM
• Aluminum Heat Sink Block
• COF Chip Heat Conduction to adjacent substrate
Mechanical fastening such as clamp, bracket, screw and additional tapes and adhesives bonding can be used in parallel
with this pad. 3M™ Adhesive Transfer Tape 91022 is an adhesive option to use with the 3M™ Thermally Conductive
Silicone Interface Pad 5515 if higher adhesion is desired in an application.
• LED Board TIM
• HD TV Address IC Chip and Scan Module
• Thin Gap Filling between board, module and chassis

Application Technique
• Firm application pressure helps develop better contact.
• Contact surfaces should be clean, dry and well unified to allow for improved contact 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.
