The purpose of an ESD protective work surface is to aid in the prevention of damage to ESD sensitive components and assemblies from electrostatic discharge. An ESD protective work surface provides protection in the following two ways:

  1. Providing an antistatic work surface area that will not allow static electricity to be generated at potentially hazardous levels.
  2. Removing the charge from a conductive object placed on the work surface. ESD protective work surfaces are catagorized into two general categories: conductive and dissipative.

A conductive work surface is defined by most documents as a material that has a surface resistivity of less than 1x10E5 ohms. Conductive materials are the quickest to ground a charge, but they can also cause damage by discharging too rapidly. Conductive materials are usually used as floormats or flooring products.

A dissipative work surface is defined as being materials having a surface resistivity of at least 1x10E5, but less than 1x10E12 ohms. Dissipative materials minimize the generation of static charges, and will dissipate a charge slow enough so that a spark will not occur. Dissipative materials are usually the preferred choice for bench top work surfaces.
