Electrostatic Discharge Information
An electrostatic discharge (ESD) can damage static-sensitive devices or microcircuitry. Proper
packaging and grounding techniques are required to prevent damage. To prevent damage due to
ESD, observe the following precautions:
• Transport products in static-safe containers such as conductive tubes, bags, or boxes.
• Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
• Cover workstations with approved static-dissipating material. Use a wrist strap connected to
the work surface as well as properly grounded tools and equipment.
• Keep the work area free of nonconductive materials such as ordinary plastic assembly aids and
foam packing.
• Ensure proper grounding before touching a static-sensitive component or assembly.
• Avoid touching pins, leads, or circuitry.
• Always place drives with the Printed Circuit Board (PCB) assembly-side down.
• Use conductive field service tools.
