Description
UniGap 3000 is a soft ceramic-filled, high performance silicone elastomer typically supplied with a polymer release liner on both sides for simple application. UniGap 3000 is intrinsically tacky which excludes air at microscopic level and requires no additional adhesive. It has excellent compression performance over a wide range of stack up tolerances and applies minimal force to electronic components. UniGap 3000 can be supplied with a fabric or film on one side for additional support during assembly.
Benefits
- Softness results in low pressures applied to devices
- High thermal conductivity and electrical isolation
- Cost effective gap filler solution for high thermal dissipation resulting in enhanced reliability
- Improved die cutting and part stability while handling
Features
- Soft and compliant gap filler with excellent thermal performance
- Thermal conductivity = 3.0 W/mK
- Integral support using fabric or polymer film
- Fabric support option provides good cut through resistance for dielectric continuity
Recommended Uses
- Any gap filler application with large component height differences can be covered with a single pad. Typically used in memory cards, VGA modules, LED assemblies and other multiple component height applications.
