ESD field service kit
The unmonitored Field Service kit is the most commonly used. Each Field Service kit includes three main components:
● Antistatic mat
● Wrist Strap
● Bonding wire
Figure 10. ESD field service kit
The antistatic mat is dissipative and must be used to safely place parts on during service procedures. When using an antistatic
mat, your Wrist Strap must be snug, connected to the mat, and to the bare-metal on the system that is being worked on. After
the mat and Wrist Strap are deployed properly, remove the components to be serviced form the ESD bag and place them 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.

The Wrist Strap and bonding wire can be connected either to:
● Your wrist and bare metal of the hardware
● Your wrist and antistatic mat, to protect hardware that is temporarily placed on the mat
NOTE: The physical connection of the Wrist Strap and bonding wire between your skin, the ESD mat, and the hardware is
known as bonding.
NOTE: Use only Field Service kits with a Wrist Strap, mat, and bonding wire. Avoid using wireless Wrist Straps.
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 to avoid accidental ESD hardware damage. Dell recommends to test the Wrist Strap and bonding wire regularly.

The wires inside an ESD strap are prone to damage over time. When using an unmonitored kit, Dell recommends to regularly
test the strap before each service call, and at a minimum, test once per week. A Wrist Strap tester is the best method for
