Appendix B
Electrostatic Discharge
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 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 flexible straps with a minimum of 1
megohm
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.
