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, drivers, 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.
