PRODUCT FAQ
-
What is the 3M™ Thermally Conductive Silicone Interface Pad 5549S used for?
The 3M™ Thermally Conductive Silicone Interface Pad 5549S is designed to provide thermal conductivity and pressure-sensitive adhesive properties in electronic devices.
-
How does this silicone interface pad differ from other similar products?
Our product offers excellent thermal conductivity, a low compression force under load, and good electrical insulation. Additionally, it has high tack adhesiveness and minimizes air gaps between surfaces.
-
Are there any special instructions I need to follow when applying the silicone interface pad?
It's important that you clean the surfaces prior to use. Apply enough pressure on both sides of the gap to reduce thickness variations across the surface. And be sure not exceed its recommended temperature rating (200°C/392°F) as doing so can compromise its performance.
3M™ Thermally Conductive Silicone Interface Pad 5549S has a medium-soft pad that conforms to uneven substrates, providing excellent wettability to fill 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. The 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
