Daan,

I agree with the other responses submitted so far.  We wear wrist straps
(metal watch-band type rather than fabric)and dissipative smocks and work on
conductive workbench surfaces.  The straps and workbenches linked and are
constantly, electronically  monitored and sound off if there is a circuit
interrupt.  We do not employ conductive shoes, floors, etc. as the wrist
strap and smock together provide good protection seated or standing. In my
opinion, you could save a lot of money and worry by implementing the more
reliable wrist straps and forgetting about the shoes.

Subject: [TN] Wrist wraps for seated operators


Hello Technet,

We've recently received some complaints from a customer who is not happy
with the fact that our operators don't wear wrist wraps during seated
operations like handsoldering and inspection. Our factory relies on
grounding through the (conductive) chairs, ESD-shoes, conductive floor and
ESD-workbenches, but the chairs are tested only once per year, which is
obviously less frequent then one would test wrist wraps.
Is the customers concern justified, and should we introduce wrist wraps ?
