What Is an Anti Static Wristband?
An anti-static wristband is a wearable device designed to safely discharge static electricity from a person to the ground. It is commonly used in electronics manufacturing and repair to prevent electrostatic discharge that can damage sensitive components like computer chips and circuit boards.
Also called:
ESD wrist strap
Grounding wrist strap
Anti-static bracelet
How It Works?
When a person moves, walks, or rubs against objects, they build up static electricity. If this static is discharged onto an electronic component, it can fry delicate circuitry.
The wristband provides a controlled path for that static to dissipate safely into the ground.
Components:
Wrist strap: Contains conductive material that touches your skin.
Grounding wire: Connects the strap to a grounding point (like an ESD mat or grounding socket).
Built-in resistor (usually 1MΩ): Protects the wearer from electric shock while allowing safe discharge of static.
Types of Anti-Static Wristbands
| Type | Description | Pros | Common Use |
|---|---|---|---|
| Wired | Connects to ground via a cord | Most reliable | Labs, repair benches |
| Wireless | Claims to ground without a cord | Portable, but less reliable | Less demanding environments |
| Single-loop | One grounding circuit | Standard type | Most ESD work |
| Dual-loop | Two separate circuits for redundancy | Higher safety | Sensitive device manufacturing |
How to Use an Anti-Static Wristband (Step-by-Step)
Wear the strap snugly around your wrist. The conductive side (often inner side) must touch your skin.
Connect the grounding wire to the wristband snap.
Plug the other end into a:
Ground port on an ESD-safe workstation
ESD grounding plug/socket
Anti-static mat connected to ground
Test the wristband with an ESD tester to ensure it's working.
Must be grounded properly to work. Simply wearing it is not enough.
Typical Specifications
Resistance: 1MΩ (safety resistor)
Cord Length: 1.8–2.5 meters (expandable coil)
Materials:
Strap: Elastic band with conductive fibers (nylon + silver/carbon fibers)
Wire: PU or PVC insulation, inner copper wire
Color: Often blue, black, or red
Compliance: ANSI/ESD S20.20, IEC 61340-5-1 standards
Who Uses Anti-Static Wristbands?
Electronics repair technicians
Assembly line workers in PCB/IC industries
Semiconductor and cleanroom staff
DIY computer builders
Labs and schools handling static-sensitive equipment
Tips & Warnings
Always test the wristband before critical work
Must be in direct skin contact (over sleeves = ineffective)
Replace if cord frays or snap becomes loose
Use with ESD-safe mats, tools, and clothing for full protection
Maintenance
Clean the strap periodically with mild soap and water
Replace damaged cords or straps
Use a wrist strap tester regularly for safety
Summary
An anti-static wristband is a simple, affordable, and crucial tool to prevent damage from electrostatic discharge. It’s essential for working with electronics, ensuring both device safety and personal protection.

Feature:
Commonly used in SMT industry and production lines.
Economical and easy to operate.
Attention:
When operating, it is to discharge anti static on human bodies to the ground through wrist strap and grounding wire, therefore, when using the product the human skin must touch the wrist strap. The grounding wire shall also be directly connected to the ground to ensure its smooth grounding and performance.
