Grounding Methods

Hardware Reference Guide
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:
I
Avoid hand contact by transporting and storing products in
static-safe containers.
I
Keep electrostatic-sensitive parts in their containers until they
arrive at static-free workstations.
I
Place parts on a grounded surface before removing them from
their containers.
I
Avoid touching pins, leads, or circuitry.
I
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:
I
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.
