basic information
Aluminum nitride (AlN) is widely used as a material for heat sinks and printed circuit boards due to its high insulation properties and high thermal conductivity. As materials with a high heat generation per unit area, such as power devices and LEDs, aluminum nitride and similar heat dissipation materials will become increasingly important in the future. Aluminum nitride (ceramics) is produced using a sintering method, but the thermal conductivity can vary significantly depending on the production method. In recent years, advancements in production techniques have led to the development of AlN with high thermal conductivity. To achieve high thermal conductivity, controlling the sintering state is crucial, which requires evaluating the fine distribution of thermal conductivity. Traditionally, measuring the thermal conductivity distribution in fine areas has been challenging, but with the thermal microscope TM3, it is possible to measure thermal conductivity with a minimum resolution of 3μm.
