4.1.6Grounding Workstations

To prevent static damage at the workstation, use the following precautions:

■Cover the workstation with approved static-dissipative material. Provide a wrist strap connected to the work surface and properly grounded tools and equipment.

■Use static-dissipative mats, heel 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 workstations.

■Avoid contact with pins, leads, or circuitry.

■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 non-conductive materials such as ordinary plastic assembly aids and Styrofoam.

■Use field service tools, such as cutters, screwdrivers and, vacuums, that are conductive.

■Use a portable field service kit with a static dissipative vinyl pouch that folds out of a work mat. Also use a wrist strap and a ground cord for the work surface. Ground the cord to the chassis of the equipment undergoing test or repair.

4.1.7Grounding Equipment

Use the following equipment to prevent static electricity damage to the equipment:

Wrist Straps are flexible straps with a minimum of 1 megohm +/- 10% resistance to the ground cords. To provide proper ground, a strap must be worn snug against the skin. On grounded mats without banana-plug connectors, connect a wrist strap with alligator clips.

Heel straps/Toe straps/Bootstraps can be used at standing workstations and are compatible with most types of boots and shoes. On conductive floors or dissipative floor mats, use straps on both feet with a minimum of 1 megohm resistance between operator and ground. To be effective, the conductive strips must be worn in contact with the skin.
