THERM-A-GAP™GEL 75 Reliability Report
The purpose of this document is to examine the thermal reliability of this high-performance thermal gel. Samples of production-scale batches were subjected to long-term aging conditions, and the thermal performance was measured over time.
Successful survival of long-term aging is demonstrated by a lack of statistically significant increase in thermal impedance of the reliability fixtures after the full aging duration. The reliability fixtures comprise GEL 75 sandwiched between two stainless-steel coupons, with thickness set by PTFE spacers. It is worth noting that the exact impedance value of the reliability fixture is not representative of the impedance value of the thermal interface material itself, but it can be used to measure changes to thermal performance over time.
●Executive Summary
THERM-A-GAP™GEL 75 is a high-performance, one-component,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. 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 125°C.
The thermal performance of THERM-A-GAP™GEL 75 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, 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 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 75 demonstrates the ability to withstand long-term aging without a reduction in thermal performance
