Preventing System Damage
Handling Parts
To prevent damaging 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 finger 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 and storing products in
static-safe containers
• Keep electrostatic-sensitive parts in their containers until they
arrive at static-free workstations
• Place parts on a grounded surface before removing them from their
containers
• Avoid touching pins, leads, or circuitry
• Always be properly grounded when touching a static-sensitive
component or assembly
Grounding
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 flexible straps
with a minimum of 1 megohm 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 floors or
dissipating floor mats. se conductive field service tools.
• Use a portable field service kit with a folding static-dissipating work
mat.
