Electronics manufacturers, we do burn-in at (elevated T°) to cause early failure for components that have a potential problem. Wafer processes have variability and that creates transistors or metal layers not in spec. It's reliability and sorting, not to adjust parametrics LMS 7.7, 7.8 and 7.9 - 5xRadio, 3xBoom, 4xDuet, 1xTouch, 1 SB2.
