Quick Thermal Fix Saves Beta Run CHALLENGE Methode was approached to quickly solve a preproduction thermal problem to save a customer's beta run. SOLUTION Our team recommended an embedded copper heat spreader in the base of the existing heat sink, thus lowering the overall thermal resistance, limiting component temperature rise. STORY A leading traction drive manufacturer was suering system failures during beta testing. The failures were caused by an inadequately sized heat sink, which was causing power electronics to overheat and fail when operated under worst-case environmental conditions. The customer needed a quick thermal x for their existing heat sink to save their beta run, buying time to devise a more permanent x.We ran thermal simulations and recommended that they embed a coppe
