Which work surface presents an opportunity for electrostatic discharge (ESD) damage?

• A. Waxed
• B. Painted
• C. Vinyl
• D. All of the above

Answer: (D)

Static charges tend to build up on insulating surfaces, and a discharge can damage sensitive electronics. Waxed, painted, and vinyl work surfaces are all nonconductive or only weakly conductive, so they can trap and hold charge created by movement, friction with clothing or tools, or separation of surfaces. Because the charge lingers on these materials, a discharge can jump to or from a device placed on the surface or touched by a person, risking ESD damage. Therefore, any of these surfaces can pose an ESD risk, making all of the above the correct description. To mitigate this, use dissipative or conductive work surfaces, grounding, humidity control, and antistatic measures on the entire workspace.
