Welcome to the Parker Chomerics How to Test a Thermal Interface Material product training module. This presentation will define and clarify the thermal testing method and equipment that Chomerics uses to determine the thermal properties across product families. The families include gap filler pads, gels, phase change materials, tapes, greases, and dielectric pads. The engineer will also review other common industry test methods to gain further insight as to why Chomerics prefers testing per ASTM D5470, as well as better understand how to compare thermal properties across competitive materials.
