  1. One of the most common IC failures are "VDD shorts". It can be immediate failures in Tier1 PCB manufacturing or Field failures. The Microprocessors and Micro-controllers are the most common victims of VDD shorts. And the root cause may surprise you. The highest risk areas is a PCB discharge event on the In-Circuit Tester, ICT. The ICT fixture has metal pogo pins that contact near the pin of the IC. The purpose is to verify the decoupling capacitor on the VDD pin. However, because the pogo pin is so close to the IC pin it easy to have a high energy injection from a PCB discharge event. The solution is simple. Use Electric Field Control on the ICT tester.
