Grounding The Work Area; Recommended Materials And Equipment - HP ProDesk 400 G4 Maintenance And Service Manual

Grounding the work area

To prevent static damage at the work area, observe the following precautions:
● Cover the work surface with approved static-dissipative material. Provide a wrist strap connected to
the 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 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.
