							Chapter 4. Removal and Replacement Preliminaries 
 
Chapter 4.0 Introduction 
This chapter provides general service information for the computer.
Adherence to the procedures and precautions described in this chapter is
essential for proper service.
Chapter 4.1 Electrostatic Discharge Information 
A sudden discharge of static electricity from your 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 can 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.
4.1.1 Generating Static
Table 4-1 shows how different activities generate static electricity and
at different electrostatic voltage levels.
Table 4-1. Typical Electrostatic Voltages
===========================================================================
-- Relative Humidity --
Event 10% 40% 55%
===========================================================================
Walking across carpet 35,000 V 15,000 V 7,500 V
Walking across vinyl floor 12,000 V 5,000 V 3,000 V
Motions of bench worker 6,000 V 800 V 400 V

Removing DIPS from Styrofoam 14,500 V 5,000 V 3,500 V

4.1.2 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.
o To avoid hand contact, transport products in static-safe containers such
as tubes, bags, or boxes.
o Protect all electrostatic parts and assemblies with conductive or
approved containers or packaging.
o Keep electrostatic sensitive parts in their containers until they arrive
at static-free stations.
o Place items on a grounded surface before removing them from their
container.
o Always be properly grounded when touching a sensitive component or
assembly.
o Place reusable electrostatic-sensitive parts from assemblies in
protective packaging or conductive foam.
Use transporters and conveyors 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.
4.1.3 Preventing Damage to Drives
To prevent static damage to diskette drives and hard drives, use the
following precautions:
o Handle drives gently, using static-guarding techniques.
o Avoid touching the connectors on the hard drive.
o Store drives in the carrying case. Use the Hard Drive Carrying case, not
the MultiBay Device Carrying Case.
o Avoid dropping drives from any height onto any surface.
o Handle drives on surfaces that have at least one inch of shock-proof
foam.
4.1.4 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.

							Method Voltage
===========================================================================
Antistatic plastic 1,500 V
Carbon-loaded plastic 7,500 V
Metallized laminate 15,000 V
===========================================================================
4.1.5 Grounding Workstations
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, foot straps, or air ionizers to give added
protection.
o Handle electrostatic sensitive components, parts, and assemblies by the
case or PCM 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, and vacuums,
that are conductive.
o Use a portable field service kit with a static-dissipative vinyl pouch
that unfolds to become 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.
4.1.6 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 with more 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
