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 nger or other conductor may damage
system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of
the devic
e.
To prevent electrostatic damage, observe the following precautions:
Avoid hand contact by transporting products in static-safe containers such as conductive tubes,
bags, or b
oxes.
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 wo
rk area free of nonconducting materials such as ordinary plastic assembly aids and
foam pa
cking.
Place parts on a grounded surface before removing them from their containers.
Avoid touching pins, leads, or circuitry.
Make s
ure 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 co
nductive 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 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 oors or dissipating oor mats.
Use conductive eld service tools.
Use a portable eld service kit with a folding static-dissipating work mat.
