Removal and Replacement Preliminaries
Maintenance and Service Guide 4–5
■
Place reusable electrostatic-sensitive parts from assemblies
in protective packaging or non-conductive foam.
■
Use transporters and conveyers made of antistatic belts and
roller bushings. Ensure that mechanized equipment used
for moving materials is wired to ground, and that proper
materials were selected to avoid static charging. When
grounding is not possible, use an ionizer to dissipate
electric charges.
4.6 Workstation Precautions
Use the following grounding precautions at workstations:
■
Cover the workstation with approved static-dissipative
material (refer to Table 4-2).
■
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, use fixtures made of static-safe materials only.
■
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 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.
