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:
I
Transport products in static-safe containers such as conductive tubes, bags, or boxes.
I
Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
I
Cover workstations with approved static-dissipating material. Provide a wrist strap
connected to the work surface and properly grounded (earthed) tools and equipment.
I
Keep work area free of nonconductive materials, such as ordinary plastic assembly aids
and foam packing.
I
Make sure you are always properly grounded (earthed) when touching a static-sensitive
component or assembly.
I
Avoid touching pins, leads, or circuitry.
I
Always place drives with the PCB-assembly-side down.
I
Use conductive field service tools.
