Removal and Replacement Preliminaries

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 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.
