| May 28, 2012 at 16:56 | comment | added | Adam Lawrence | @stevenvh It's what the manufacturers claim, i.e. what they always say when they see this sort of stuff. That being said, I've seen my fair share of random production blow-ups where ESD couldn't be proven, but the yield improved once a broken wrist or heel strap was replaced. (The ESD doesn't cause the crater, but it damages the die so that when power is applied, kapow) | |
