REMOVAL AND REPLACEMENT
PRELIMINARIES

This chapter provides general service information for the Compaq Expansion base.
Adherence to the procedures and precautions described in this chapter is essential for
proper service.

4.1 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.

Removal and Replacement Preliminaries 4-1

Generating Static

Table 4-1 shows how different activities generate static electricity and at different
electrostatic voltage levels.

Table 4-1

Typical Electrostatic Voltages

Packing PCBs in foam-lined box 21,000 V 11,000 V 5,000 V

NOTE: 700 volts can degrade a product.

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 ground
precautions are necessary to prevent damage.

■ Protect all electrostatic sensitive parts and assemblies with nonconductive 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 electrostatic-sensitive parts from assemblies in protective packaging

or nonconductive foam.

Use transporters and conveyers made of antistatic belts and 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.

4-2 Removal and Replacement Preliminaries

Preventing Damage to Drives

To prevent static damage to drives, follow these precautions:

■ Handle drives gently, using static-guarding techniques.

■ Store drives in the hard drive carrying case. Do not use the MultiBay device carrying

case.

■ Avoid dropping drives from any height onto any surface.

■ Handle drives on surfaces that have at least one inch of shock-proof foam.

■ Avoid touching the connectors on the hard drive.

Grounding Methods

The method for grounding 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. When
standing, use footstraps and a grounded floor mat.

Static Shielding Protection Levels

Method Voltage

Antistatic plastic 1,500 V
Carbon-loaded plastic 7,500 V
Metallized laminate 15,000 V

Removal and Replacement Preliminaries 4-3

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.

4-4 Removal and Replacement Preliminaries

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

■ Nonconductive foam

■ Conductive tabletop workstations with ground cord of one megohm resistance

■ Static-dissipative table or floor mats with hard tie to ground

■ Field service kits

■ Static awareness labels

■ Wrist straps and footwear straps providing one megohm +/- 10% resistance

■ Material handling packages

■ Nonconductive plastic bags

■ Nonconductive plastic tubes

■ Nonconductive tote boxes

■ Metal tote boxes

■ Opaque shielding bags

■ Transparent metallized shielding bags

with the part with which they belong. Using an improper screw during reassembly can
damage the Compaq Expansion Base.

IMPORTANT: As each subassembly is removed from the Compaq Expansion Base, it
should be placed away from the work area to prevent damage.

4-6 Removal and Replacement Preliminaries

Cables and Connectors

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 the cables are routed in such a way that they
cannot be caught or snagged by parts being removed or replaced. Handle flex cables
with extreme care; they can tear easily.

CAUTION: When servicing the Compaq Expansion Base, ensure that cables are placed in
their proper location during the reassembly process. Improper cable placement can
damage the Compaq Expansion Base.

Plastic Parts

Plastic parts can be damaged by the use of excessive force during disassembly and
reassembly. When handling the plastic parts, use care. Use a bezel removal tool to
separate plastic components. Apply pressure only at the points designated in the
maintenance instructions.
