Grounding the work area

To prevent static damage at the work area:
●
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.

Recommended materials and equipment

It is recommended that the following materials and equipment be used to prevent static electricity:
●
Antistatic tape
● Antistatic smocks, aprons, or sleeve protectors
●
Conductive bins and other assembly or soldering aids
● Conductive foam
●
Conductive tabletop workstations with ground cord of one-megohm ± 10% resistance
● Static-dissipative table or floor mats with hard tie to ground
●
Field service kits
● Static awareness labels
●
Wrist straps and footwear straps providing one-megohm ± 10% resistance
●
Material handling packages
●
Conductive plastic bags and tubes
●
Conductive tote boxes
●
Opaque shielding bags
●
