<div class="moz-cite-prefix">I guess that over the years I just
adopted a subconsciously ESD-aware working style. Like, if I'm
about to put a card in a machine, I'm holding the card by the
backplate and I touch the case with the other hand first so that
me, the machine's ground, and the card's ground go to the same
potential. Now, that is NOT a good practicewhen you are dealing
with higher voltages with higher currents available (e.g., tube
amps), which is why wrist straps etc. have a ~1M resistor in
series - perfectly adequate for discharging static but will tend
to not put a few mA across your ticker.<br>

In 30 years, I've always simply followed the rules for grounding
myself frequently during repair. I've never need to use mats or
wristbands, and I have yet (knock on wood) to <i>accidentally</i>
destroy a component due to ESD. I've shorted things together and
done a fair number of other relatively stupid things early-on in
my practice. I remember the first 14.4 modem I got, I was so
excited that I forgot to screw down the card... it touched the
9600 bps modem I had and when I turned on the computer, I had a
fantastic light show. :)<br>
<br>
But ESD? I've only succeeded in using it to destroy things when I
intended to (e.g., as part of experimentation). As long as you
ground first, and ground frequently, it's really not possible to
screw things up. Unless, of course, you shift/shuffle/slide your
feet around, or are working in an extremely dry environment, but
then why wouldn't you simply have a workbench that is itself
grounded, so that you're always touching a grounded surface?<br>
