Bob,

This is kind of a tricky question. If you have defined the ESD protected
area (per ANSI/ESD 20.20) as the entire room, then per the spec
requirement any personnel entering the room should have heel straps. If
the ESD protected area is only defined as the workstations within the
room, then someone entering the room will not need them. However, as
Graham pointed out, product should not be affected as long as an
ungrounded person comes no closer than 12 inches from unprotected
product (not in an ESD protective container, such as a bag or tote).

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?
