Personal grounding methods and equipment

Use the following equipment to prevent static electricity damage to equipment:
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.
Method
Antistatic plastic
Carbon-loaded plastic
Metallized laminate

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
