Maintenance and Service Guide

Workstation guidelines
Follow these grounding workstation guidelines:
● Cover the workstation with approved static-shielding material.
● Use a wrist strap connected to a properly grounded work surface and use properly grounded tools
and equipment.
● Use conductive eld service tools, such as cutters, screw drivers, and vacuums.
● When xtures must directly contact dissipative surfaces, use xtures made only of static-safe materials.
● Keep the work area free of nonconductive materials, such as ordinary plastic assembly aids
and polystyrene foam.
● Handle ESD-sensitive components, parts, and assemblies by the case or PCM laminate. Handle these items
only at static-free workstations.
● Avoid contact with pins, leads, or circuitry.
● Turn o power and input signals before inserting or removing connectors or test equipment.
Equipment guidelines
Grounding equipment must include either a wrist strap or a foot strap at a grounded workstation.
● When seated, wear a wrist strap connected to a grounded system. Wrist straps are exible straps with a
minimum of 1 MΩ ±10% resistance in the ground cords. To provide proper ground, wear a strap snugly
against the skin at all times. On grounded mats with banana-plug connectors, use alligator clips to connect
a wrist strap.
● When standing, use foot straps and a grounded oor mat. Foot straps (heel, toe, or 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 foot straps on both feet with a minimum of 1 MΩ ±10% resistance between
the operator and ground. To be eective, the conductive must be worn in contact with the skin.
HP recommends the following grounding equipment to prevent electrostatic damage:
● Antistatic tape
● Antistatic smocks, aprons, and sleeve protectors
● Conductive bins and other assembly or soldering aids
● Nonconductive foam
● Conductive tabletop workstations with ground cords of 1 MΩ ±10% resistance
● Static-dissipative tables or oor mats with hard ties to the ground
● Field service kits
● Static awareness labels
● Material-handling packages
● Nonconductive plastic bags, tubes, or boxes
● Metal tote boxes
● Electrostatic voltage levels and protective materials
