To help back up the trainings of my employees about the potential dangers of
ESD, I'm looking for the most ESD sensitive components.
To be of use, the components have to be:
1) cheap (they will be destroyed in the demonstration)
2) easy to obtain (MR heads don't count for this reason)
3) easy to show some form of functionality (MR heads are also not good for
this reason)
The things that come to mind are old CMOS 4000 series logic IC's (the newer
types seem to be much more robust), small signal MOSFET's (2N700x), or maybe
a small signal RF MOSFET.
The intent is to build something like a LED flasher / sequencer, remove the
said ESD sensitive component, make sure the air ionization is turned off,
people are not wearing the normal ESD protective stuff (smocks, foot straps
and wrist straps), or using the conductive chairs or are on conductive
paint, etc, and have the said component passed around the room. Hopefully
someone will have a nice furry sweater on, and the humidity will be low. If
necessary, mount the part on a piece of PCB designed to encourage one person
to be touching the ground / power / source pins, while the other person
would first grab the end with the gate or I/O pins / pins exposed.
Any suggestions on what is the most sensitive component for this
application?
