1. What is thermal putty?
Thermal putty is a soft, formable thermal interface material designed to fill irregular gaps between heat-generating components and heat sinks or metal housings. It provides excellent thermal conductivity and ensures stable heat dissipation even in uneven or complex surfaces.
2. What is thermal putty made of?
Thermal putty is typically made from silicone or polymer compounds blended with thermally conductive fillers such as ceramic, aluminum oxide, or metal particles. This combination allows it to maintain high thermal conductivity while remaining soft and easy to apply.
3. What is the difference between thermal putty and thermal pad?
Thermal putty is a semi-fluid material that can conform perfectly to uneven surfaces, providing better contact and heat transfer in irregular gaps. Thermal pads, on the other hand, are pre-formed solid sheets that are easier to handle but less adaptable to surface variations. Thermal putty offers higher flexibility and often better thermal performance for complex assemblies.
4. How do I apply thermal putty?
Before application, clean both contact surfaces thoroughly to remove dust and oil. Then apply an even layer of thermal putty using a spatula, syringe, or automated dispenser. Ensure full coverage of the gap without excessive thickness. After assembly, the putty spreads to form a uniform thermal interface that minimizes air pockets.
5. What does thermal conductivity (W/m·K) mean for thermal putty?
Thermal conductivity represents the material’s ability to transfer heat. A higher value indicates better heat dissipation. For example, a thermal putty with 8 W/m·K or higher is suitable for high-performance CPUs, GPUs, or power devices, while lower values are used for standard electronic applications.
6. Can thermal putty be reused?
Generally, thermal putty is designed for single-use applications. Once it is compressed and shaped to fit a component, removing and reapplying it may reduce its performance and cleanliness. For the best results, new putty should be applied each time a device is reassembled.
7. Does thermal putty provide electrical insulation?
Yes, most silicone-based thermal putties are electrically insulating, which helps prevent short circuits in electronic assemblies while maintaining high thermal conductivity. However, some formulations are electrically conductive, depending on application needs.
