HP Omen X - Grounding Workstation Guidelines

● Avoid contact with pins, leads, or circuitry.
● Place reusable electrostatic-sensitive parts from assemblies in protective packaging or conductive
foam.
Personal grounding methods and equipment
Use the following equipment to prevent static electricity damage to electronic components:
● Wrist straps are exible straps with a maximum of 1 MΩ ±10% resistance in the ground cords. To
provide proper ground, a strap must be worn snug against bare skin. The ground cord must be
connected and t snugly into the banana plug connector on the grounding mat or workstation.
● Heel straps/Toe straps/Boot straps can be used at standing workstations and are compatible with
most types of shoes or boots. On conductive oors or dissipative oor mats, use them on both feet with
a maximum of 1 MΩ ±10% resistance between the operator and ground.

Grounding the work area
To prevent static damage at the work area, take 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 o power and input signals before inserting and removing connectors or test equipment.
● Use xtures made of static-safe materials when xtures must directly contact dissipative surfaces.
● Keep work area free of nonconductive materials such as ordinary plastic assembly aids and Styrofoam.
● Use eld service tools, such as cutters, screwdrivers, and vacuums, that are conductive.
Recommended materials and equipment
HP recommends the following 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 oor mats with hard tie to ground
