Hi All,

What are the pro's and con's of using polished, untreated, concrete flooring as a part of ESD control instead of "dissipative" or "conductive" flooring?

Regards,

Jo

If we're talking an unsealed and bare concrete floor, the answer is - it depends. Time of year, humidity, lots of things. The properties of the concrete can change daily.

Another thing to keep in mind; just because something might exhibit antistatic tendencies does not mean that it will also discharge a human being properly. Discharge or dissipation is directly related to conductivity, NOT antistatic properties.

Based on this, an unsealed bare floor is inexpensive and may initially or occasionally seem to exhibit the required attributes, but there are no guarantees whatsoever. You cannot rely on it.

If you need to have an anti-static and dissipative floor, concrete isn't acceptable, IMO.

I don't know your environment/ business, but you could save money by only having components handled at approved ESD stations. These can be controlled locally by having correct grounding + wrist straps, humidifiers or ionizers etc.

Treat all other areas as non-ESD handling approved and protect the components appropriately with antistatic bags etc
