How to prevent electrostatic discharge

To prevent damage to the system, you must follow certain precautions when setting up the system or handling parts. 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 make sure you are 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 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.

•Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet when standing on conductive ﬂoors or static-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 HP authorized reseller install the part.

NOTE:

For more information on static electricity, or for assistance with product installation, contact your HP authorized reseller.
