4.5 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 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.
