Grounding the work area

To prevent static damage at the work area, follow these precautions:
● Cover the work surface with approved static-dissipative material.
● Use a wrist strap connected to a properly grounded work surface and use 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 the work area free of nonconductive materials, such as ordinary plastic assembly aids and
polystyrene foam.
● Use conductive field service tools, such as cutters, screwdrivers, and vacuums.
●
Avoid contact with pins, leads, or circuitry.

Recommended materials and equipment

HP recommends certain materials and equipment 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 1 MΩ ±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 1 MΩ ±10% resistance
● Material handling packages
