Anti-Static Mat
Wrist Strap and Bonding Wire
The wrist strap and bonding wire can be either directly connected between your wrist and bare metal on
the hardware if the ESD mat is not required, or connected to the anti-static mat to protect hardware that is
temporarily placed on the mat. The physical connection of the wrist strap and bonding wire between your
skin, the ESD mat, and the hardware is known as bonding. Use only Field Service kits with a wrist strap, mat,
and bonding wire. Never use wireless wrist straps.
Always be aware that the internal wires of a wrist strap are prone to damage from normal wear and tear,
and must be checked regularly with a wrist strap tester in order to avoid accidental ESD hardware damage.
It is recommended to test the wrist strap and bonding wire a minimum of once per week.
