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.
