Electrostatic Discharge

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.

Preventing Electrostatic Discharge

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 of 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 directly
against the skin.
Use heelstraps, toestraps, or bootstraps at standing workstations.
Wear the straps on both feet when standing on conductive floors
or dissipating floor mats.
