Compaq CONTURA AERO Maintenance And Service Manual page 21

To prevent static damage at the workstation, use the following precautions:
o Cover the workstation with approved static dissipative material. Provide
a wrist strap connected to the work surface and properly grounded tools
and equipment.
o Use static dissipative mats, heel straps, or air ionizers to give added
protection.
o Handle electrostatic sensitive components, parts, and assemblies by the
case or PCB laminate. Handle them only at static free workstations.
o Avoid contact with pins, leads, or circuitry.
o Turn off power and input signals before inserting and removing connectors
or test equipment.
o Use fixtures made of static safe materials when fixtures must directly
contact dissipative surfaces.
o Keep work area free of nonconductive materials such as ordinary plastic
assembly aids and Styrofoam.
o Use field service tools, such as cutters, screwdrivers, vacuums, that are
conductive.
o Use a portable field service kit with a static dissipative vinyl pouch
that folds out of a work mat.
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 the
equipment:
Wrist Straps are flexible straps with a minimum of 1 megohm +/- 10%
resistance to 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 boots and shoes. On conductive floors or
dissipative floor mats, use them on both feet with a minimum of 1 megohm
resistance between operator and ground. To be effective, the conductive
strips must be worn in contact with the skin.
Recommended Materials and Equipment
Other materials and equipment that are recommended for use in preventing
static electricity include:
o Antistatic tape
o Antistatic smocks, aprons, or sleeve protectors
Also use a wrist strap and a ground cord
