Is wonder if there's a strong correlation between whether you experience static zaps in your daily life and your propensity to fry chips with ESD.
When you fry a chip is it obvious because you experience a zap?
If so, then that would make all this "make sure you're grounded" ceremony less mysterious — because unless you feel a zap (even a tiny one) you probably haven't fried a chip, and it doesn't generally happen in environments where you don't feel zaps.
Obvious caveat: "feeling" a zap is not a precise measurement. But perhaps "zaps fry chips" is a lie which reveals a greater truth.
- IIsi50MHz 1y agoMany common board components have ESD-withstand ratings of 250V, far below what you can feel. The assembled product may be somewhat robust (including case), but most ESD events are not detectable without specialised equpment.
