Electrostatic discharge information
To prevent damage to the system, be aware of the precautions you need to follow when setting up the
system or handling parts. A discharge of static electricity from a
fi
nger or other conductor may damage
system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of
the device.
To prevent electrostatic damage, observe the following precautions:
•
Avoid hand contact by transporting products in static-safe containers such as conductive tubes,
bags, or boxes.
•
Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
•
Cover workstations with approved static-dissipating material. Provide a wrist strap connected to
the work surface and properly grounded (earthed) tools and equipment.
•
Keep work area free of nonconducting materials such as ordinary plastic assembly aids and
foam packing.
•
Place parts on a grounded surface before removing them from their containers.
•
Avoid touching pins, leads, or circuitry.
•
Make sure that you are properly grounded when touching a static-sensitive component or
assembly.
•
Place hard drives with the Printed Circuit Board (PCB) side down.
•
Use conductive
fi
eld service tools.
Grounding methods
There are several methods for grounding. Use one or more of the following methods when handling or
installing electrostatic sensitive parts:
•
Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis.
Wrist straps are
fl
exible straps with a minimum of 1 megohm ±10% resistance in the ground
cords. To provide proper ground, wear the strap snug against the skin.
•
Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet
when standing on conductive
fl
oors or dissipating
fl
oor mats.
•
Use conductive
fi
eld service tools.
•
Use a portable
fi
eld service kit with a folding static-dissipating work mat.
