Electrostatic Discharge
A sudden discharge of static electricity from a finger or other conductor can destroy
static-sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but
damage occurs. An electronic device exposed to electrostatic discharge (ESD) may not be
affected at all and will work perfectly throughout a normal cycle. Or it may function
normally for a while, then degrade in the internal layers, reducing its life expectancy.
Networks built into many integrated circuits provide some protection, but in many cases,
the discharge contains enough power to alter device parameters or melt silicon junctions.

Preventing Electrostatic Damage to Equipment
Many electronic components are sensitive to ESD. Circuitry design and structure determine
the degree of sensitivity. The following proper packaging and grounding precautions are
necessary to prevent damage:
Protect all electrostatic parts and assemblies with conductive or approved containers
or packaging.
●
Keep electrostatic sensitive parts in their containers until they arrive at static-free
stations.
●
Place items on a grounded surface before removing them from their
container.
●
Always be properly grounded when touching a sensitive component or assembly.● Place reusable electronic-sensitive parts from assemblies in protective packaging or
conductive foam.
●
Use transporters and conveyors made of antistatic belts and metal roller bushings.
Mechanized equipment used for moving materials must be wired to ground and
proper materials selected to avoid static charging. When grounding is not possible,
use an ionizer to dissipate electric charges.
●
The accompanying table shows typical static-shielding protection levels afforded by
different protective packaging materials.
Static-Shielding Protection Levels
Method Voltages
Antistatic Plastic 1,500
Carbon-Loaded Plastic 7,500
Metallized Laminate 15,000
Top
Preventing Damage to Drives
To prevent static damage to hard drives, use the following precautions:
Handle drives gently, using static-guarding techniques.● Store drives in the original shipping containers.● Avoid dropping drives from any height onto any surface.●
Compaq.com - Compaq Presario Maintenance and Service Guide - 5700 Series
http://www.compaq.com/athome/support/msgs/5700/rr.html (3 of 7) [1/10/2002 11:55:29 AM]

Handle drives on surfaces that have at least one inch of shock-proof foam.● Always place drives PCB assembly side down on the foam.●
Top
Grounding Methods
The method for grounding must include a wrist strap or a foot strap at a grounded
workstation. When seated, wear a wrist strap connected to a grounded system. When
standing, use footstraps and a grounded floor mat.
Top
Grounding Workstations
To prevent static damage at the workstation, use the following 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 give 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 nonconductive materials such as ordinary plastic assembly
aids and Styrofoam.
●
Use field service tools, such as cutters, screwdrivers, vacuums, that are conductive.● Use a portable field service kit with a static dissipative vinyl pouch that folds out of 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.

http://www.compaq.com/athome/support/msgs/5700/rr.html (4 of 7) [1/10/2002 11:55:29 AM]

Grounding Equipment
Use the following equipment to prevent static electricity damage to the equipment:
Wrist Straps are flexible straps with a minimum of 1 mega ohm +/- 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 mega ohm resistance between
operator and ground. To be effective, the conductive strips must be worn in contact
with the skin.
●
Top
Recommended Materials and Equipment
Other materials and equipment that are recommended for use in preventing static
electricity include:
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 mega ohm
of resistance
●
Static dissipative table or floor mats with hard tie to ground● Field service kits● Static awareness labels● Wrist straps and footwear straps providing 1 mega ohm (+/- 10%) resistance● Material handling packages● Conductive plastic bags● Conductive plastic tubes● Conductive tote boxes● Metal tote boxes● Opaque shielding bags● Transparent metallized shielding bags●

Tool Requirements
Torx T-8, T-10, and T-15 screwdrivers (included in kit number 130619-001)● Needle-nose pliers● Flat-bladed screwdriver● Diagnostics software●
Top
Screws
The screws used in these products are not interchangeable. If an incorrect screw is used
during the reassembly process, it could cause damage to the unit. Compaq strongly
recommends that all screws removed during the disassembly process be kept with the part
that was removed, then returned to their proper locations.
IMPORTANT: As each subassembly is removed from the computer, it should be
placed away from the work area to prevent damage
●
Top
Cables and Connectors
Most cables used throughout the unit are ribbon cables (Figures 4-1, 4-2, 4-3, 4-4, and
4-5). These cables must be handled with extreme care to avoid damage.
Apply only the tension required to seat or unseat the cables during insertion or removal
from the connector. Handle cables by the connector whenever possible. In all cases, avoid
bending, twisting, or tearing the cables, and ensure that cables are placed in such a way
that they cannot be caught or snagged by parts being removed or replaced.
The numbered cables show the recommended configuration for the ribbon cables. The
shaded lines indicate alternative configurations for additional optional hard drives, tape
drives, and diskette drives.

CAUTION: When servicing these computers, ensure that cables are
placed in their proper location during the reassembly process.
Improper cable placement can cause severe damage to the unit.
