Thermally Conductive Pastes & Gels
These materials are screened, stenciled or dispensed and require virtually no compressive force to conform under typical assembly pressures. Good surface wetting results in low interfacial resistance. Rather messy to apply for low volumes, for large quantities an automatic dispensing system is normally used. Clean removal is difficult.
Typical Applications:
- Standard dc/dc power converter and dc/ac inverter,
- High performance CPUs
- Between any heat generating semiconductor and heat sink
- Custom power modules
- Telecommunications and automotive electronics
Typical Features:
- Type: Silicone/non silicone
- Viscosity: 10,000-100,000 cps
- Thermal conductivity: 0.75 – 6.0 W/m-k
- Temperature range: -55°C up to 240°C
- Insulation strength: up to 15,000 Volt/mm
Benefits:
- Excellent surface wetting, can be implemented by automatic dispenser, low compressive force, cost effective.
