Thermal Interface Material (TIM) is a thermally conductive substance applied between heat-generating components and heat sinks to improve heat transfer efficiency.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Thickness | 0.1-2.0 mm | |
| Viscosity | 100-500 Pa·s (for pastes) | |
| Thermal Resistance | 0.1-1.0 °C·cm²/W | |
| Dielectric Strength | >5 kV/mm | |
| Thermal Conductivity | 1-12 W/m·K (typical range) | |
| Operating Temperature | -50°C to 200°C |

Thermal paste is a viscous compound applied thinly for minimal thermal resistance, ideal for uneven surfaces. Thermal pads are pre-formed, solid sheets easier to apply and reusable, but typically have lower conductivity.
TIM degradation depends on type and conditions; thermal pastes may dry out in 2-5 years, while pads last longer. Replace if temperatures rise unexpectedly or during component maintenance.
Some TIMs with metal fillers (e.g., silver-based) are electrically conductive and must be used carefully to avoid short circuits. Non-conductive options (ceramic or silicone-based) are safer for sensitive applications.
