Removal and Replacement Preliminaries
Maintenance and Service Guide
4–5
■
Store reusable electrostatic-sensitive parts from assemblies in
protective packaging or nonconductive foam.
■
Use transporters and conveyors made of antistatic belts and
roller bushings. Ensure that mechanized equipment used for
moving materials is wired to ground and that proper materials
are 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-shielding 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 only 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.
