How Do ESD Wristbands Work?

ESD wrist straps come in a variety of materials, but the general concept for each is the same; to provide a path for electrostatic ground.

For an ESD control wrist strap to work, it is either connected to earth bonding points fitted into workstations, typically via 10 mm press studs, or come with a removable coiled cord and crocodile clip for mobile applications.

The strap is fastened around your wrist using an adjustable band. The wristband should be worn snug to the skin with its coil cord connected to a common point ground which is connected to ground, preferably equipment ground. Typically, the alligator clip is attached to the computer or sensitive electronic device being worked on.

An anti static strap must be connected to a grounding source like a bonding plug in conjunction with a ground lead in order for them to be effective.

Once an ESD wrist strap has been secured to the wrist and connected to the earth bonding point or sensitive piece of equipment, you are safe to work without fear of ESD occurring. This allows you and your workforce to go about your daily tasks freely and drastically reduces the chances of static electricity building up.
