B Electrostatic Discharge Preventing Electrostatic Damage 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 when setting up the system or handling parts: • Avoid hand contact by transporting and storing products in static-safe containers.
Electrostatic Discharge 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% resistance in the ground cords. To provide proper ground, wear the strap snugly against the skin.
