Electrostatic Discharge Information

An electrostatic discharge (ESD) 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 (earthed) tools and equipment.

• Keep work area free of nonconductive materials, such as ordinary plastic assembly aids

and foam packing.

• Make sure that you are always properly grounded (earthed) when 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.
