Grounding the work area
To prevent static damage in the work area:
ā
Cover the work surface with approved static-dissipative material. Use a wrist strap connected to
the work surface, and properly grounded tools and equipment.
ā
Use static-dissipative mats, foot straps, or air ionizers to give added protection.
ā
Handle electrostatic-sensitive components, parts, and assemblies by the case or PCB laminate.
Handle them only in static-free work areas.
ā
Disconnect power and input signals before inserting and removing connectors or test equipment.
ā
Use fixtures made of static-safe materials when fixtures must directly contact dissipative surfaces.
ā
Keep work area free of nonconductive materials, such as plastic assembly aids and Styrofoam.
ā
Use field service tools (such as cutters, screwdrivers, and vacuums) that are conductive.
