THERM-A-GAP TC50™ Reliability Report (TR1102)
●THERM-A-GAP™ TC50 is a high-performance, one-component, dispensable thermal interface material. The paste-like consistency enables superior performance and long-term thermal stability. This material is designed to be dispensed in applications requiring low compressive forces and minimal thermal resistance for maximum thermal performance. This document outlines the examination of the thermal reliability of this high-performance gap filler. Samples of manufacturing batches of THERM-A-GAP™ TC50 were compared after being subjected to long-term environmental aging under dry heat and heat & humidity conditions, as well as temperature cycling from -40°C to 125°C.
●The thermal performance of THERM-A-GAP™ TC50 was examined after being subjected to multiple environmental stress tests. The thermal impedance of the aged samples did not experience a significant increase after any of the treatments studied. After 1000-hour dwell at 125°C and 1000 temperature cycles from -40°C to 125°C, there was no statistically significant change in impedance according to one-way ANOVA with the Tukey method for multiple comparisons at a 95% confidence level. There was a substantial decrease in impedance after 1000-hour dwell at 85°C/85% relative humidity, which is indicative of improved thermal performance. This decrease in impedance may be a result of decreased interfacial resistance caused by the thermal interface material wetting out the substrate surface.
●Based on these results, THERM-A-GAP™ TC50 demonstrates the ability to withstand long-term aging without a reduction in thermal performance.
