Service Preparation
Safety Considerations
Before performing service procedures, review the following safety information.
Electrostatic Discharge Information
A discharge of static electricity can damage static-sensitive devices or microcircuitry. Proper
packaging and grounding techniques are necessary precautions to prevent damage. To
prevent electrostatic damage, 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 and properly grounded tools and equipment.
• Keep the work area free of nonconductive materials, such as ordinary plastic assembly
aids and foam packing.
• Be sure you are always properly grounded when touching a static-sensitive component or
assembly.
• Avoid touching pins, leads, or circuitry.
• Always place drives PCB assembly-side down.
• Use conductive field service tools.
