TLDR of original issue: - motherboard overvolted the CPU, likely causing a runaway failure and burning the silicon. Overcurrent protection did not trigger. This video is the follow up showing some interesting tools they used to inspect the CPU: - Microscope - Cross-section + microscope - 3D CT scan - Scanning acoustic microscope (SAM) - Scanning electron microscope (SEM) - Energy dispersive Xray (EDXA) The tools and methods are the interesting part, the results not as much, basically "yeah it burned". But in other cases, or with more detail of the die, could probably pinpoint where exactly the failure occurred. |
