that is temporarily placed on the mat. The physical connection of the wrist strap and bonding wire between your skin, the
anti-static mat, and the hardware is known as bonding. Use only Field Service kits with a wrist strap, anti-static mat, and
bonding wire. Never use wireless wrist straps. Always be cautious 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 at least once per week.
● ESD Wrist Strap Tester – The wires inside an ESD strap are prone to damage over time. When using an unmonitored kit, it
is a best practice to regularly test the strap prior to each service, and at a minimum, test once per week. A wrist strap tester
is the best method for doing this test. To perform the test, plug the bonding-wire of the wrist-strap into the tester while it
is strapped to your wrist and push the button to test. A green LED is lit if the test is successful; a red LED is lit and an alarm
sounds if the test fails.
NOTE: It is recommended to always use the traditional wired ESD grounding wrist strap and protective anti-static mat
when servicing Dell products. In addition, it is critical to keep sensitive parts separate from all insulator parts while servicing
the computer.
Transporting sensitive components
When transporting ESD sensitive components such as replacement parts or parts to be returned to Dell, it is critical to place
these parts in anti-static bags for safe transport.
