Preventing Electrostatic Damage
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 when setting up the system or handling parts:
•
•
•
•
•
•
•

•
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 To Prevent Electrostatic Damage
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 grounding, wear the strap snug against
the skin.
Use heel straps, toe straps, or bootstraps at standing workstations. Wear the straps on
both feet when standing on conductive floors or dissipating floor mats.
Use conductive field service tools.
Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, have an authorized
HP service provider install the part.

authorized reseller.
