Measuring Thermal Conductivity of Thermal Interface Materials with MTPS

Importance of Measuring Thermal Conductivity of Thermal Interface Materials with MTPS

Thermal conductivity is an important metric for evaluating the performance of thermal interface materials (TIMs). An accurate method must be used toethod must be used to measure the thermalcaccuratelyed Transient Plane Source (MTPS) method is an ideal solution for the measurement of thermal conductivity for TIMs. The MTPS method can test a wide range of materials, from solids to liquids, powders, and pastes, over a wide temperature range (-50oC to 200oC). Additionally, the MTPS method can test compressible TIMs, such as those composed of pastes, adhesives, and potting compounds, by allowing for a controlled or specified compression range. Technology allows for using both the MTPS and more traditional Flex Transient Plane Source (TPS) and Transient Line Source (TLS) methods.

The thermal conductivity of a TIM is critical for evaluating its performance. By using an accurate method to measure the thermal conductivity, such as the MTPS method, researchers and engineers can make better decisions when selecting a TIM for their application and can optimize thermal performance

The MTPS method has several benefits, such as a rapid measuring process, little sample preparation, and a broad range of suitable materials, such as solids, powders, and thin films. Compared to other procedures, it is also less sensitive to sample thickness and contact resistance.

The MTPS method is used in various fields, including thermal management, materials science, and engineering. It offers valuable data for material characterization, quality assurance, and the creation of effective thermal insulation or heat transfer systems.
