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 personal computer chassis. Wrist straps are flexible straps with a minimum of 1 Mohm +/- 10 percent resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.
