Thin film thermal conductivity has obtained 2 invention patents, patent number: 201710832672.2 patent number: 201810067584.2
Thin film thermal conductivity has obtained 2 utility model patents, patent number: 201720505805.0 patent number 201720511457.8

A few days ago, three domestic first-class scientific research institutions have selected Jiayitong’s thin film thermal conductivity test system as their professional instrument for testing the thermal conductivity of thin film materials. There are also dozens of colleges and research institutes in cooperation with Jiayitong. Negotiate and purchase. Jiayitong film thermal conductivity test system has become the best choice for domestic first-class scientific research institutions!

The film thermal conductivity test system adopts the 3ω test method, which effectively overcomes the heat radiation phenomenon on the sample surface, and can well test the thermal conductivity of micro/nano film materials. It can be widely used to assist the research and development of various functional thin film materials, including integrated circuit heat dissipation materials, aerospace materials, thermoelectric materials and devices, information storage and optoelectronic devices, etc. At present, it has won unanimous recognition from units including the Shanghai Institute of Microsystem and Information Technology of the Chinese Academy of Sciences, Jiaxing College, and third-party testing institutions. 

“3ω test method”

The metal strip is etched on the surface of the sample, and a current with a frequency of ω is passed through the two ends of the metal strip. The two electrodes in the middle of the metal strip generate a small voltage signal V_3ω with a frequency of 3ω. The thermal conductivity is derived indirectly from V_3ω.
