The need for higher thermal conductivity fillers, such as aluminum nitride, to deal with an increase in the heat output from future semiconductors has arisen, as most of them are now packaged in a silica epoxy polymer composite. Thermal conductivity testing was performed on the aluminum nitride composite using a thermal constants analyzer and the highest reading was 3.39 W/mK, approximately 15 times higher than pure epoxy. Based on the results, ...
This article analyzes the basic criteria for determining experimental times to use in thermal conductivity experiments, using the thermal constants analyzer. Researchers have determined an interval to which test times correlate, for accurate thermal conductivity and diffusivity results. During this research, scientists also determined the possibility of testing both thermal conductivity and thermal diffusivity from one single measurement. Throughout this experiment, the researchers also expanded on the theory, calculations and ...
This article outlines the general theory behind the Transient Plane Source (TPS) Technique.To test these arrangements, scientists tested two materials, Cecorite 130P and Corning 9606 Pyroceram....
This article explains the theory behind the Transient Plane Source (TPS) technique. The method measures the thermal conductivity and diffusivity of materials (solids, liquids, gels, etc.), in a rapid, non-invasive and highly accurate manner. The TPS method is a great technique to be used for thermal characterization as it has a wider thermal conductivity range (0.005 – 500 W/mK) and an easy set-up. The sensor serves as both a temperature gauge and ...
The transient plane source method was used to perform thermal conductivity, thermal diffusivity, and specific heat capacity measurements. Thermal transport properties of several thermal greases were characterized using TPS and data were compared to supplier data, received by other methods, to determine accuracy of the TPS method....
