Handle all static-sensitive components in a static-safe area. If possible, use anti-static floor pads and workbench pads.

When unpacking a static-sensitive component from its shipping carton, do not remove the component from the anti-static packing 

material until you are ready to install the component. Before unwrapping the anti-static packaging, ensure that you discharge static 

electricity from your body.

Before transporting a static-sensitive component, place it in an anti-static container or packaging.

ESD field service kit 

The unmonitored Field Service kit is the most commonly used service kit. Each Field Service kit includes three main components: anti-static 
mat, wrist strap, and bonding wire.

Components of an ESD field service kit

The components of an ESD field service kit are:

Anti-Static Mat

 – The anti-static mat is dissipative and parts can be placed on it 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 any 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. ESD-sensitive 

items are safe in your hand, on the ESD mat, in the system, or inside a bag.

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 at least once per week.

ESD Wrist Strap Tester

 – The wires inside of 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 call, and at a minimum, test once per week. A wrist strap tester is the best 

method for doing this test. If you do not have your own wrist strap tester, check with your regional office to find out if they have one. 

To perform the test, plug the wrist-strap's bonding-wire 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.

Insulator Elements 

– It is critical to keep ESD sensitive devices, such as plastic heat sink casings, away from internal parts that are 

insulators and often highly charged.

Working Environment 

– Before deploying the ESD Field Service kit, assess the situation at the customer location. For example, 

deploying the kit for a server environment is different than for a desktop or portable environment. Servers are typically installed in a rack 

within a data center; desktops or portables are typically placed on office desks or cubicles. Always look for a large open flat work area 

that is free of clutter and large enough to deploy the ESD kit with additional space to accommodate the type of system that is being 

repaired. The workspace should also be free of insulators that can cause an ESD event. On the work area, insulators such as Styrofoam 

and other plastics should always be moved at least 12 inches or 30 centimeters away from sensitive parts before physically handling any 

hardware components

ESD Packaging 

– All ESD-sensitive devices must be shipped and received in static-safe packaging. Metal, static-shielded bags are 

preferred. However, you should always return the damaged part using the same ESD bag and packaging that the new part arrived in. 

The ESD bag should be folded over and taped shut and all the same foam packing material should be used in the original box that the 

new part arrived in. ESD-sensitive devices should be removed from packaging only at an ESD-protected work surface, and parts should 

never be placed on top of the ESD bag because only the inside of the bag is shielded. Always place parts in your hand, on the ESD mat, 

in the system, or inside an anti-static bag.

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.

ESD protection summary 

It is recommended that all field service technicians use the traditional wired ESD grounding wrist strap and protective anti-static mat at all 
times when servicing Dell products. In addition, it is critical that technicians keep sensitive parts separate from all insulator parts while 
performing service and that they use anti-static bags for transporting sensitive components.
