THERM-A-GAP™ GEL 40NS Reliability Report
●THERM-A-GAP™ GEL 40NS is a high-performance, one-component, fully-cured dispensable thermally conductive gel. 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 maximal thermal performance. The non-silicone nature of GEL 40NS provides added benefits of eliminating the risks of silicone oil bleeding and migration within electronics assemblies. This document outlines the examination of the thermal reliability of this high-performance gap filler after being subjected to long-term environmental aging under dry heat, heat & humidity conditions, and temperature cycling from -40°C to 100°C.
●he thermal performance of THERM-A-GAP™ GEL 40NS 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 100°C and 125°C, 1000 hours at 85°C/85% relative humidity, and 1000 temperature cycles from -40°C to 125°C, there was no statistically significant increase in impedance according to one-way ANOVA with the Tukey method for multiple comparisons. The mean value for thermal impedance decreased slightly for each aging treatment, indicating an improvement in thermal performance. This improvement can likely be attributed to enhanced wetting at the interface between the gel and the reliability fixture.
●Based on these results, THERM-A-GAP™ GEL 40NS demonstrates the ability to withstand long- term aging without a reduction in thermal performance.
