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 Damage

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.
