> Destructive static charges are induced on nearby conductors, such as
human skin, and delivered in the form of sparks passing between
conductors, such as when the surface of printed board assembly is
touched by a person having a static charge potential. [..] It is important to note that usually the static damage level for components cannot be felt by humans. (Less than 3,000 volts.)
Less than 3000 volts cannot be felt by humans? Should be 3000 millivolts right? i.e. 3 volts...
It's 3000V, but the energy delivered can be absolutely minute on a human scale, even for the highly sensitive nervous system. But metal oxide layers (what static discharge is often blowing holes in) are not on a human scale, they're atoms thick. And highly insulating, which leads to teravolts/metre field gradients.
For discharge that you can feel and see, the energy is even higher, but damage can be done far below this level.
Considering static discharge is a spark, I assume 3.000 volts is the correct scale. When I wince from a static discharge generally there's visible spark.

That's not 3 volts.
