Figure 11. ESD Field Service Kit
The anti-static mat is dissipative and should be used to safely place parts on during service procedures. When using an
anti-static mat, your wrist strap should be snug and the bonding wire should be connected to the mat and to bare-metal on the
system being worked on. Once deployed properly, service parts can be removed from the ESD bag and placed directly on the
mat. Remember, the only safe place for ESD-sensitive items are in your hand, on the ESD mat, in the system, or inside a bag.
Figure 12. Anti-Static Mat
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.
