MindShaRE: Decapping Chips for Electromagnetic Fault Injection (EMFI)

This piece outlines a decapping effort on a GigaDevice GD32F407Z microcontroller to enable measurement and better target EM fault injection, comparing mechanical, chemical, thermal, and optical approaches and ultimately using hot sulfuric acid due to equipment limitations. It emphasizes safety precautions, practical constraints (e.g., lack of a fume hood, working outdoors), and the goal of locating the die within the package to narrow the probe search area.
