Grounding guidelines
Electrostatic discharge damage
Electronic components are sensitive to electrostatic discharge (ESD). Circuitry design and structure
determine the degree of sensitivity. Networks built into many integrated circuits provide some protection,
but in many cases, ESD contains enough power to alter device parameters or melt silicon junctions.
A discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or
microcircuitry. Even if the spark is...

Packaging and transporting guidelines
Follow these grounding guidelines when packaging and transporting equipment:
●To avoid hand contact, transport products in static-safe tubes, bags, or boxes.
●Protect ESD-sensitive parts and assemblies with conductive or approved containers or packaging.
●Keep ESD-sensitive parts in their containers until the parts arrive at static-free workstations.
●Place items on a grounded surface before removing items from their containers.
●Always be properly grounded when...

Equipment guidelines
Grounding equipment must include either a wrist strap or a foot strap at a grounded workstation.
●When seated, wear a wrist strap connected to a grounded system. Wrist straps are flexible straps
with a minimum of one megohm ±10% resistance in the ground cords. To provide proper ground,
wear a strap snugly against the skin at all times. On grounded mats with banana-plug connectors,
use alligator clips to connect a wrist strap.
●When standing, use foot straps and a grounded floor mat....
