3M™ Thermally Conductive Silicone Interface Pad 5515S is a slightly conformable and medium-hard pad with thermal conductivity of 2.7 W/m-K (QTM-500). This pad is the "S" version of 5515, featuring a supporting layer for easy handling and assembly. This pad consists of a slightly tacky silicone elastomeric sheet filled with thermally conductive ceramic particles. It is designed to transfer heat from heat generating components to heat sinks and cooling devices, improving device reliability and extending the component's life.

3M™ Thermally Conductive Silicone Interface Pad 5515S has a medium-hard pad that conforms to uneven substrates, filling gaps for improved thermal performance. The "S" supporting layer (permanent film carrier) has a non-tacky surface, providing excellent workability, puncture resistance, and the flexibility to rework materials. TThe thin, firm, low-tack layer provides easy handling for pre-assembly and die-cutting. This pad provides robust thermal management for applications in a variety of market segments, such as consumer electronics, automotive, LED lighting, medical devices, communication infrastructure, and aerospace & defense.


Recommended Applications:
Heat transfer between PCB and heat sink
Integrated chip (IC) packaging heat conduction
Chip on film (COF) heat dissipation
Gap filling in electronic devices
Decrease of compression stress to electronic parts by thermal pad softness


Examples:
LED displays
Electric vehicle (EV) batteries
Wireless charging units
Satellite navigation
Sensors
Process control equipment
Test & measurement devices
