Measuring the Thermal Conductivity of Copper

Copper (Cu) is among the most thermally conductive metals and is often selected for use as heat spreaders in electronics. The high thermal efficiency of copper makes it a better solution than some lower priced solutions.

As the thermal conductivity of the material is a critical performance attribute, an effective means of verifying the performance of the material is highly desirable. Ideally, researchers are seeking a fast, easy means of verifying the thermal conductivity of the material as incoming material quality increasingly becomes a concern.

C-Therm Modified Transient Plane Source (MTPS) technique was recently extended in offering a broader range of testing capabilities in highly-conductive metals. Recent test results on the three samples of pure copper are presented below:

C-Therm’s Trident Thermal Conductivity Platform is able to measure thermal conductivity using three methods, including the MTPS method mentioned above:

  • Modified Transient Plane Source method
  • Transient Line Source Method
  • Transient Plane Source Method
