We used to call them mouse toilets 😊

If they are not conductive/ESD Safe or even dissipative, then they
aren't worth a shit.

How can they 'evolve' into that and not make it out of the right
polymer? Pretty sad.


There's no reason that most SMT parts need to be in static dissipative
packaging. Their capacitance to the outside world is so small that even
at kilovolts of bias it won't store enough energy to do any damage.

Picking up a small MOSFET by its gate pin might cause a problem on
account of the voltage divider formed by the gate capacitance and the
package capacitance, but that's about it.

Once it's mounted to a board, so the discharge has someplace to go to,
and you come along charged to 10 kV, _then_ you have to worry.
