ESD Grounding Methods for Anti Static Mats

Anti Static ESD Mat Grounding Cables

Do you need anti static mat instructions? Do you know how to set up an ESD mat? In this article, I show examples of how to choose ESD grounding methods for anti static mats.

ESD Grounding Methods for Anti Static Mats

In practice, most anti static mats are “grounded” to ensure that there is no risk of electricity becoming static on the top surface of the mat.

Anti Static Mats are used with grounding cables to ground ESD

Electrical outlets are normally the best ground for a mat in any building. This is because the wiring of outlets typically follows the piping of the building to earth underneath the building.

The connection of the outlet with earth underneath the building makes it unlikely that grounding the mat to the outlet will put it out of electrical balance with the building.

To “ground” anti static mats, we insert a conductive snap on the corner of the anti static mat.

On top of this snap, we then attach grounding cables.

Grounding cables typically come with 1 meg ohm resistors (1 x 106 ohms) to ensure that electricity moving through them is always traveling at a “static dissipative” rate.

Grounding cables made in the United States also typically end in an “eyelet”- a #10 ring terminal- to screw directly into a standard US electrical outlet.

They either ground only the mat, or serve as a common point ground for both the mat and a wrist strap.
