Thermal Interface Material or TIM is the interface between a heatsink, and a device. Thermal adhesive or thermal grease improve the heat sink’s performance by filling air gaps between the heat sink and the heat spreader on the device. China Heat Sink Inc. Thermal offers a wide selection of thermal interface pads to provide both an attachment method and improved thermal transfer. These phase-change Thermal Interface Materials (TIMs) are designed to completely fill interfacial air gaps and voids, displacing entrapped air between power dissipating electronic components. Phase-change materials are designed to maximize heat sink performance and improve component reliability. Upon reaching the required melt temperature, the pad will fully change phase and attain minimum bond-line thickness (MBLT) – less than 0.001 inch or 0.0254mm, and maximum surface wetting. This results in practically no thermal contact resistance due to a very small thermal resistance path. At room temperature, the materials are solid and easy to handle. This allows them to be consistently and cleanly applied as dry pads to a heat sink or component surface. With light clamping pressure it will readily conform to both mating surfaces.

WHAT IS A TIM (THERMAL INTERFACE MATERIAL)?
Radian works with a variety of interface material providers, and many of our products come with pre-applied interface materials, we also work with our customers to select the most appropriate interface material for the application.
When using a Thermal Interface Material, care must be taken when storing as the condition of adhesion is directly affected by the storage temperature, and humidity environment. Ideal storage conditions are below 25°C, and a humidity of 40-80%.
