Removal and Replacement Preliminaries

Maintenance and Service Guide

■

Store reusable electrostatic-sensitive parts from assemblies in 
protective packaging or nonconductive 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 
are selected to avoid static charging. When grounding is not 
possible, use an ionizer to dissipate electric charges.

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, 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.
