Removal and Replacement Preliminaries

4.5 Workstation Precautions

Use the following grounding precautions at workstations:
■
Cover the workstation with approved static-shielding material
(refer to
■
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 that must directly contact dissipative
surfaces, only use fixtures made 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.
4.6 Grounding Equipment and
Methods
Grounding equipment must include either a wrist strap or a foot
strap at a grounded workstation.
■
When seated, wear a wrist strap connected to a grounded
system. Wrist straps are flexible straps with a minimum of
one megohm ±10% resistance in the ground cords. To
provide proper ground, wear a strap snugly against the skin
at all times. On grounded mats with banana-plug connectors,
use alligator clips to connect a wrist strap.
