Transistor ESD detector
Transistor ESD detector
(OP)
I remember reading a while back about a transistor that has a very consistent breakdown voltage. I believe it a was around 150V so it was handy to build into a circuit to monitor if an ESD event had occurred (if it is blown your trace experienced ESD). I vaguely remember it being a Fairchild part but don't remember the part number. Does anybody know of this part or have any other recomendations for an ESD detector? Thanks.

If you know the situation well enough to put a monitor there, you can put a ESD discharger there as well to ensure that no damage occurs whatsoever.
If you want an ESD monitor, you do a websearch for one:

There are literally dozens of choices. 3M sells a cheap alarm monitor for about $80:

I've never heard of a single device like you describe though.

While the approach is interesting, the point at which you determine that you've had a problem is too far downstream to make immediate corrections and salvage the production.

If you are having a problem with failed boards at the end of the manufacturing process, then that is your indication of ESD. Don't jump to the conclusion that a work station is causing the problem. Do you check your components before installing them? Remember that it is probably more likely that ESD damage is done handling and/or transporting the boards from station to station than during the process at the stations.
However, don't be discouraged in your approach. While experience suggests that this may not be the best aproach, many of us gained our experience by trying something that turned out to be not the best approach. Even though we may not have always solved our immediate problem, we almost always learned something that was valuable sooner or later.
