Inge,
Don't know that I agree with this.  I think it all comes down to how
extensive your ESD training is and how actively it is maintained.  We have
similar situations in our facilities.  Our engineers know not to touch
"live boards" without being strapped.  Our technicians have permission to
backhand anyone into the middle of next week who reaches for a live board
without being strapped.

I get asked the old "while you are here can you look at this" all the time.
My first question is always "is it live?".  Second is usually, "got an
extra strap?".  I do that because Sally or Betty is just waiting to whack
me one.

There are no paragraphs for that obvious and given case: of course
anyone MUST use heel straps! The one who says he will not touch
anything, one minute after gave this promise, he may be charged to
several Volts or even hundreds Volts (if he hasn't ESD shoes) and after
two minutes he may have forgotten not to touch anything. Ask some guys
to walk around and then place their feet on the ESD tester, and you'll
probably have proof enough. 10 VDC discharge at 10 picoseconds is enough
to cause damage to certain 1.5 V devices!

Subject: [TN] ESD question

Good Morning all,

A question regarding ESD has come up in our facility. Our SMT area has
ESD flooring and the question that came up is that one of our
instructors says that anyone entering the room must have heel straps on
and another says that if a person is just going into the room and not
touching product, they don't need heel straps. Who is correct?
