ESD wrist straps and cords are essential components in personal grounding systems used in Electrostatic Protected Areas (EPAs). Their primary purpose is to safely discharge any static electricity that may accumulate on the human body, thereby protecting sensitive electronic components during handling, assembly, or repair.
The wrist strap consists of a flexible band that fits snugly around the wrist, with a conductive inner surface that ensures contact with the skin. It connects via a coiled cord to a common grounding point, such as an ESD-safe workbench or mat. This continuous grounding prevents electrostatic discharge (ESD) events that could damage microchips, integrated circuits, and other static-sensitive devices.
