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
±
10 percent 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.
