●
Wrist straps
are flexible straps with a maximum of one-megohm ± 10% resistance in the ground cords.
To provide proper ground, a strap must be worn snug against bare skin. The ground cord must be
connected and fit snugly into the banana plug connector on the grounding mat or workstation.
●
Heel straps/Toe straps/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 them on both feet with
a maximum of one-megohm ± 10% resistance between the operator and ground.

Grounding the work area
To prevent static damage at the work area, use the following precautions:
●
Cover the work surface with approved static-dissipative material. Provide a wrist strap connected to the
work surface and properly grounded tools and equipment.
●
Use static-dissipative mats, foot straps, or air ionizers to give added protection.
●
Handle electrostatic sensitive components, parts, and assemblies by the case or PCB laminate. Handle
them only at static-free work areas.
●
Turn off power and input signals before inserting and removing connectors or test equipment.
●
Use fixtures made of static-safe materials when fixtures must directly contact dissipative surfaces.
●
Keep work area free of nonconductive materials such as ordinary plastic assembly aids and Styrofoam.
●
Use field service tools, such as cutters, screwdrivers, and vacuums, that are conductive.
Recommended materials and equipment
Materials and equipment that are recommended for use in preventing static electricity include:
●
Antistatic tape
●
Antistatic smocks, aprons, or sleeve protectors
●
Conductive bins and other assembly or soldering aids
●
Conductive foam
●
Conductive tabletop workstations with ground cord of one-/- 10% resistance
●
Static-dissipative table or floor mats with hard tie to ground
●
Field service kits
●
Static awareness labels
●
Wrist straps and footwear straps providing one-/- 10% resistance
