Is ESD overhyped?
I have seen many engineers talk about ESD protection but I had never seen its effects myself. I made many small DIY projects and I have used bare hands to touch ICs and their pins,but nothing got destroyed(I mean ICs functioned well). Is it really that serious? Please tell and also its mitigating measures. I experimented with a mosfet just now by rubbing my fingers on its terminals. It is an n-channel mosfet called IRF510,and its datasheet is here . I observed that mosfet is working well by checking with a multimeter in diode mode i.e drain is connected to common of multimeter and source to positive one.
Yes, damage due to ESD (electro-static discharge) is real. Just because you haven't seen it isn't much evidence of anyt …

Many ESD problems are "latent" that is they do not sofort show up....some time later things will stop working :)

The favored method of data transfer is USB stick.
On a winter day, the cnc programmer picks up enough static on the short walk from his desk to the machine, that it would discharge upon inserting the USB stick. In the older of the machines (mid 2000's generation), this discharge would sometimes reset the whole thing, as if you flipped the power switch. Ruining whatever was being cut, which could be multiple parts in the setup, and if a skinny drill or tap was engaged at that moment, the sudden stop could break that.
That is the kind of thing the EU's stricter ESD requirements are meant to prevent.
