Grounding the Work Area
To prevent static damage at the work area, use the following 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
Styrofoam.
Use field service tools, such as cutters, screwdrivers, and vacuums, that are conductive.
