4-4 Removal and Replacement Preliminaries
Workstation Precautions
Use the following grounding precautions at workstations:
■ Cover the workstation with approved static-dissipative material (refer to Table 4-2
later in this chapter).
■ Use a wrist strap connected to a properly grounded work surface and use properly
grounded tools and equipment.
■ Use field service tools, such as cutters, screwdrivers, and vacuums that are
conductive.
■ When using fixtures that must directly contact dissipative surfaces, use fixtures
made of static-safe materials only.
■ Keep 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 them 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.
