Grounding the work area

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