How do I ground materials and carts to a conductive tile floor?
Add conductive drag chains and casters to materials and carts to ground them to esd flooring. The photo to the right shows a recently completed Conductive Vinyl tile installation. This client plans to use “wire shelf carts” to move electronics assemblies around the floor. Even though this floor is grounded and conductive, the cart will not be grounded as its wheels are insulators. Static cannont drain through an insulator even if that insulator is resting on an esd, anti static floor. The cart shown in the photo does not have a conductive drag chain or conductive casters. Adding conductive wheels or drag chains to the cart provides a path for charge in the cart to drain to ground, in this case the conductive floor. Read more.
