Dell EMC Latitude 3300, Service Manual

Touching the chassis before handling parts does not ensure adequate ESD protection on parts with increased sensitivity to ESD
damage.
Figure 3. Chassis "Bare Metal" Grounding (Unacceptable)
• Handle all static-sensitive components in a static-safe area. If possible, use anti-static floor pads and workbench pads.
• When handling static-sensitive components, grasp them by the sides, not the top. Avoid touching pins and circuit boards.
• 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, be sure to discharge static
electricity from your body.
• Before transporting a static-sensitive component, place it in an anti-static container or packaging.
The ESD Field Service Kit
The unmonitored Field Service kit is the most commonly used. Each Field Service kit includes three main components: anti-static mat,
wrist strap, and bonding wire.
Figure 4. 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.
