Preventing electrostatic discharge
About this task
To prevent damaging the system, be aware of the precautions you must follow 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:
Procedure
• 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.
