When using fixtures that must directly contact dissipative
surfaces, only use fixtures made of static-safe materials.
Keep the work area free of nonconductive materials, such as
ordinary plastic assembly aids and Styrofoam.
Handle electrostatic-sensitive components, parts, and
assemblies by the case or PCM laminate. Handle these items
only at static-free workstations.
Avoid contact with pins, leads, or circuitry.
Turn off power and input signals before inserting or
removing connectors or test equipment.
4.7 Grounding Equipment and
Methods
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,
connect a wrist strap with alligator clips.
When standing, use foot straps and a grounded floor mat.
Foot straps (heel, toe, or boot straps) can be used at standing
workstations and are compatible with most types of shoes
or boots. On conductive floors or dissipative floor mats, use
foot straps on both feet with a minimum of one megohm
resistance between the operator and ground. To be effective,
the conductive strips must be worn in contact with the skin.
