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:
■
Transport products in static-safe containers such as conductive tubes,
bags, or boxes.
Writer:
Bruce Sullivan
Part Number:
■
Keep electrostatic-sensitive parts in their containers until they arrive at
static-free stations.
■
Cover workstations with approved static-dissipating material. Provide a
wrist strap connected to the work surface and properly grounded tools
and equipment.
■
Keep the work area free of non-conductive materials such as ordinary
plastic assembly aids and foam packing.
■
Always be sure you are 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.
