Keith,
Well, I never pulled the tape from the paper: I just pulled the wire
out from the tape... And, I, being grounded, was in contact with the
leads. Don't know if that makes a difference or not!
Breakdown voltage: I can assure you that almost ANY ESD is larger
than the breakdown voltage. It's just that ESD is usually a very small
amount of power that the capacitor will easily absorb. For it to damage
the cap, it has to charge it to the breakdown voltage. In the case of
polarized caps, I'm not sure what these short term reverse voltages do.

... no, I didn't tape down the "sensitive" components.

>From an ESD point of view, that's cool, but when you pull the tape away
from the paper, you're generating a static charge which may make it to
your 1/2 populated board and cause problems with components on the
board, right? Maybe it is a low probability issue or maybe having the
board on a mat eliminates the risk. I don't know.

Capacitors ... I have never heard of any of these types of components
being damaged by
ESD: Has anyone?

I work with one EE who says there is an issue with caps where the
breakdown voltage (is there such a thing?) of a very small value cap may
be less than the voltage generated by ESD. Still, caps of all values at
this company are considered not ESD sensitive.
In my case, I'm really not smart enough to know what is and is not a
real problem so it is just easier to treat everything as if it is
sensitive even if I know (or think) it isn't.
73!
