4.6 Workstation Precautions

Use the following grounding precautions at workstations:

■Cover the workstation with approved static-shielding material (refer to Table 4-2,“Static-Shielding Materials”).

■Use a wrist strap connected to a properly grounded work surface and use properly grounded tools and equipment.

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

■When using fixtures must directly contact dissipative surfaces, use fixtures made only 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.
