What is It
Proper tool selection
A tool is a handheld device that aids in accomplishing a task. Tools range from
a traditional metal cutting part of a machine to an element of a computer program
that activates and controls a particular function.
Preparing for the task to be undertaken includes proper tool selection.
1. How do you select the best tool for the job? First, know and understand in
detail the scope of work to be accomplished, second, plan for the scope taking into
account the sequence of tasks.
2. Selecting the best tool for each task requires training in the proper use of
the tools, field experience in their safe use, and following the manufacturer’s
guidance and instructions for that specific tool.
3. When obtaining the tool all the associated tooling and consumable parts,
as recommended by the manufacturer, must be included. In addition, related
consumable parts must also be selected and used according to their manufacturer’s
instructions.
Safe Use of tools
Once selected, use the tool for the purpose for which it was designed. Not all
tools come with detailed instructions, but there are those that do spell out the safety
―Do’s and Don’ts for your safety. If there are set-up/use options, operator judgment
must always be based on what is the safest way to use the tool.
Environmental Safety and Health Program requires the following:
Clean tools and equipment work more efficiently. At the end
of each working day clean the tools and equipment you used and
check them for any damage. If you note and damage,
tag the tool as faulty and organize a repair or replacement.
Electrical current can travel over oily or greasy surfaces. Keep
electrical power hand tools free from dust and dirt and make
sure they are free of oil and grease.
All workshop hand tools and equipment should have
maintenance schedule. Always complete the tasks described on
the schedule at the required time. This will help to keep the
hand tools in safe working order.
Store commonly used hand tools in an easy-to-reach location. If
a tool or a piece is too difficult to return, it could be left on a
workbench or on the floor where it will become a safety hazard.
Keep your work area tidy. This will help you work
more
efficiently and safely.
HARDWARE TOOLS
To complete hardware repairs, it is important to have a toolkit that should contain
all of the necessary tools. As you gain experience, you will learn which tools to have
available for different types of jobs. Hardware tools are grouped into these four
categories:
•
•
•
•
Electro-Static Discharge (ESD) tools
Hand tools
Cleaning tools
Diagnostic tools
Electro-Static Discharge (ESD) Tools
Static electricity is easily generated by friction on carpets, tile flooring, clothing,
hair, fabric, and etc. The friction of moving air alone will charge suspended particles
and cause the buildup of static electrical charges on people and objects in the
environment. Grounded antistatic work mats used with antistatic wrist straps
provide the most basic means for the controlled discharge of electrostatic electricity.
Anti-static wrist strap – used to prevent ESD damage to
computer equipment.
Anti-static mat – used to stand on or place hardware
on
to prevent static electricity from building up.
Anti-static bag- is a packaging material that is specially
designed to help prevent static electricity interacting with
sensitive electrical components.
Hand Tools
A hand tool is a device for performing work on a material or a physical
system using only hands. The hand tools can be manually used employing force,
or electrically powered, using electrical current
Flat head screwdriver – used to loosen or tighten slotted
screws.
Philips head screwdriver – used to loosen or tighten
crosshead screws.
Torx screwdriver - used to loosen or tighten screws that
have a star-like depression on the top, a feature that is
mainly found on laptop.
Hex driver – sometimes called a nut driver, is used to
tighten nuts in the same way that a screwdriver
tightens screws.
Needle-nose plier – used to hold small parts
Wire cutter – used to strip and cut wires
Tweezers – used to manipulate small parts.
Flashlight or Headlight – used to light up areas that
you cannot see well.
Soldering Pencil – a tool used to join two or more metal
conductors with the support of soldering lead melted
around it.
Desoldering Tool – a tool used to unsoldered unwanted
parts or component in the circuit with the support of
soldering pencil.
Precision
Screwdrivercomes
from
different
interchangeable heads which can be switched; used for
tiny screws found in the inner part of the components of
a compute
Crimping tool- used to connect wires into the metal
components of a computer; it is designed to connect or
attach a connector at the end of a cable to be able to link
or connect to a network of other computers
Cleaning Tools
Having the appropriate cleaning tools is essential when maintaining or
repairing computers. Using these tools ensures that computer components are not
damaged during cleaning. They also make computers tidy and dirt-free.
Lint-free cloth – used to clean different computer
components without scratching or leaving debris.
Compressed air – used to blow away dust and debris
from different computer parts without touching the
components.
Cable ties – used to bundle cables neatly inside and
outside of a computer.
Parts organizer – used to hold screw, jumpers, fasteners
and other small parts and prevents them from getting
mixed together.
Paint brush- its long and soft natural bristles can be used
to dust off the surface of circuit boards and its hard-toreach areas
Rubbing alcohol- used to wipe away sticky substances on
the surface of components; its quick evaporation lessens
the chance of causing electrical damage to components
Diagnostic Tools
Computers are easier to use and more dependable with each new generation
of hardware and operating system update, but that doesn't mean they're problemfree. Diagnostic tools are used to test the integrity of circuits and functionality of
ports.
LAN Tester- is a device used to test the network
connection.
Digital Multimeter- also called Volt-Ohm- Milliammeter
(VOM), a handy and battery operated tool used to
measure voltge, current and resistance; and effective tool
to check or diagnose if the circuits in a component is
working or not.
Multimeter – used to test the integrity of circuits and the
quality of electricity in computer components.
Loopback Adapter – used to test the functionality of
computer ports.
Toner probe – the toner part is connected to a cable at
one end using specific adapters, such as an RJ-45,
coaxial, or metal clips. The toner generates a tone that
travels the length of the cable. The probe part traces the
cable. When the probe is in near proximity to the cable
to which the toner is attached, the tone can be heard
through a speaker in the probe.
PROPER USE OF TOOLS
Proper Use of ESD Tools
The purpose of an antistatic wrist strap is to equalize the electrical charge
between you and the equipment. The antistatic wrist strap is a conductor that
connects your body to the equipment that you are working on. When static electricity
builds up in your body, the connection made by the wrist strap to the equipment, or
ground, channels the electricity through the wire that connects the strap. The wrist
strap has two parts and is easy to wear:
1. Wrap the strap around your wrist and secure it
using the snap or Velcro. The metal on the back of the
wrist strap must remain in contact with your skin at
all times.
2. Snap the connector at the end of the wire to the
wrist strap, and connect the other end either to the
equipment or to the same grounding point that the
antistatic mat is connected to. The metal skeleton of
the case is a good place to connect the wire. When
connecting the wire to equipment that you are working
on, choose an unpainted metal surface. A painted
surface does not conduct the electricity as well as
unpainted metal.
An antistatic mat is slightly conductive. It works by drawing static electricity
away from a component and transferring it safely from equipment to a grounding
point: 1. Lay the mat on the workspace next to or under the computer case. 2. Clip
the mat to the case to provide a grounded surface on which you can place parts as
you remove them from the system. Reducing the potential for ESD reduces the
likelihood of damage to delicate circuits or components.
Proper Use of Hand Tools
A technician needs to be able to properly
use each tool in the toolkit. This topic covers
many of the various hand tools used when
repairing computers.
Screws Match each screw with the
proper screwdriver. Place the tip of the
screwdriver on the head of the screw. Turn the
screwdriver clockwise to tighten the screw and
counterclockwise to loosen the screw.
Screws can become stripped if you over-tighten them with a screwdriver. A
stripped screw, may get stuck in the screw hole, or it may not tighten firmly. Discard
stripped screws.
Flat head screwdriver Use a flat head screwdriver when you are working with
a slotted screw. Do not use a flat head screwdriver to remove a Phillips head screw.
Never use a screwdriver as a pry bar. If you cannot remove a component, check to
see if there is a clip or latch that is securing the component in place.
CAUTION: If excessive force is needed to remove or add a component, something is
probably wrong. Take a second look to make sure that you have not missed a screw
or a locking clip that is holding the component in place. Refer to the device manual
or diagram for additional information.
Phillips head screwdriver Use a Phillips head screwdriver with crosshead
screws. Do not use this type of screwdriver to puncture anything. This will damage
the head of the screwdriver.
Hex driver Use a hex driver to loosen and tighten bolts that have a hexagonal
(six-sided) head. Hex bolts should not be over-tightened because the threads of the
bolts can be stripped. Do not use a hex driver that is too large for the bolt that you
are using.
CAUTION: Some tools are magnetized. When working around
electronic devices, be sure that the tools you are using have not
been magnetized. Magnetic fields can be harmful to data stored
on magnetic media. Test your tool by touching the tool with a
screw. If the screw is attracted to the tool, do not use the tool.
Part retriever, Needle-nose pliers, or tweezers The part retriever, needle-nose
pliers, and tweezers can be used to place and retrieve parts that may be hard to reach
with your fingers. Do not scratch or hit any components when using these tools.
CAUTION: Pencils should not be used inside the computer to change the setting of
switches or to pry off jumpers. The pencil lead can act as a conductor and may
damage the computer components.
Proper Use of Cleaning Materials
Keeping computers clean inside and out is
a vital part of a maintenance program. Dirt can
cause problems with the physical operation of
fans, buttons, and other mechanical components.
On electrical components, an excessive buildup
of dust will act like an insulator and trap the heat.
This insulation will impair the ability of heat
sinks and cooling fans to keep components cool,
causing chips and circuits to overheat and fail.
CAUTION: When compressed air is used to clean inside the computer, the air should
be blown around the components with a minimum distance of four inches from the
nozzle. The power supply and the fan should be cleaned from the back of the case.
CAUTION: Before cleaning any device, turn it off and unplug the device from the
power source.
Computer Cases and Monitors Clean computer cases and the outside of
monitors with a mild cleaning solution on a damp, lint-free cloth. Mix one drop of
dishwashing liquid with four ounces of water to create the cleaning solution. If any
water drips inside the case, allow enough time for the liquid to dry before powering
on the computer.
LCD Screens Do not use ammoniated glass cleaners or any other solution on
an LCD screen, unless the cleaner is specifically designed for the purpose. Harsh
chemicals will damage the coating on the screen. There is no glass protecting these
screens, so be gentle when cleaning them and do not press firmly on the screen.
CRT Screens to clean the screens of CRT monitors, dampen a soft, clean, lintfree cloth with distilled water and wipe the screen from top to bottom. Then use a
soft, dry cloth to wipe the screen and remove any streaking after you have cleaned
the monitor.
Clean dusty components with a can of compressed air. Compressed air does
not cause electrostatic buildup on components. Make sure that you are in a wellventilated area before blowing the dust out of the computer. A best practice is to wear
a dust mask to make sure that you do not breathe in the dust particles.
Blow out the dust using short bursts from the can. Never tip the can or use
the compressed air can upside down. Do not allow the fan blades to spin from the
force of the compressed air. Hold the fan in place. Fan motors can be ruined from
spinning when the motor is not turned on.
Component Contacts Clean the contacts on components with isopropyl
alcohol. Do not use rubbing alcohol. Rubbing alcohol contains impurities that can
damage contacts. Make sure that the contacts do not collect any lint from the cloth
or cotton swab. Blow any lint off the contacts with compressed air before
reinstallation.
Keyboard Clean a desktop keyboard
with compressed air or a small, hand-held
vacuum cleaner with a brush attachment.
CAUTION: Never use a standard vacuum
cleaner inside a computer case. The plastic
parts of the vacuum cleaner can build up static
electricity and discharge to the components. Use only a vacuum approved for
electronic components.
Mouse Use glass cleaner and a soft cloth to clean the outside of the mouse.
Do not spray glass cleaner directly on the mouse. If cleaning a ball mouse, you can
remove the ball and clean it with glass cleaner and a soft cloth. Wipe the rollers clean
inside the mouse with the same cloth. Do not spray any liquids inside the mouse.
