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.

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.

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.
