This research proposes a practical evaluation methodology for long-term stability of thermal interface material (TIM). Instead of the ASTM D5470 testing standard, a thermal test vehicle with a sensors and heaters embedded thermal test chip was designed to This research proposes a practical evaluation methodology for long-term stability of thermal interface material (TIM).
