Safety Considerations
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.
Always be properly grounded when touching a static-sensitive component or assembly.
