D Electrostatic Discharge

This appendix discusses ways to prevent damage to your system due to Electrostatic Discharge

(ESD). This appendix addresses the following topics:

“Handling Parts” (page 75)

“Grounding” (page 75)

Handling Parts

To prevent damage to your system, you must take precautions when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor can damage system boards or other static-sensitive devices. This type of damage can reduce the life expectancy of the device.

To prevent electrostatic damage, observe the following precautions:

• Avoid hand contact; transport and store 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 handling a static-sensitive component or assembly.

Grounding

Use one or more of the following grounding methods when handling or installing electrostatic-sensitive parts:

• 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 resistance in the ground cords.

To provide proper ground, wear the strap snug against the skin.

• Heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet when standing on conductive floors or dissipating floor mats. Use conductive field service tools.

• A portable field service kit with a folding static-dissipating work mat.
