Grounding Workstations; Grounding Equipment - Compaq Armada e500s Maintenance And Service Manual

Grounding Workstations

To prevent static damage at the workstation, follow these precautions:
Cover the workstation with approved static-dissipative material. Provide a wrist strap
connected to the work surface and properly grounded tools and equipment.
Use static-dissipative mats, heel straps, or air ionizers to provide added protection.
Handle electrostatic sensitive components, parts, and assemblies by the case or PCB
laminate. Handle them only at static-free workstations.
Avoid contact with pins, leads, or circuitry.
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 conductive materials such as ordinary plastic assembly aids
and plastic foam.
Use field service tools, such as cutters, screwdrivers, and vacuums, that are
conductive.
Use a portable field service kit with a static-dissipative vinyl pouch that folds out
into a work mat. Also, use a wrist strap and a ground cord for the work surface.
Ground the cord to the chassis of the equipment undergoing test or repair.

Grounding Equipment

Use the following equipment to prevent static electricity damage to equipment:
Wrist Straps are flexible straps with a minimum of one megohm +/- 10% resistance in
the ground cords. To provide proper ground, a strap must be worn snug against the skin.
On grounded mats without banana-plug connectors, connect a wrist strap with alligator
clips.
Heelstraps/Toestraps/Bootstraps can be used at standing workstations and are
compatible with most types of shoes or boots. On conductive floors or dissipative floor
mats, use them on both feet with a minimum of one megohm resistance between the
operator and ground. To be effective, the conductive strips must be worn in contact with
the skin.
