Grounding the work area
To prevent static damage in your work area:
●
Cover the work surface with approved static-dissipative material. Use 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 in static-free work areas.
●
Disconnect 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 that are conductive, such as cutters, screwdrivers, and vacuums.
