Introduction to various categories of basic hand tools, including driving, soldering, slicing, boring, cutting, and auxiliary tools.
Detailed discussion on screwdrivers, their function to insert or remove screws, and types of screwdrivers.
Explanations on different types of screwdrivers: slotted for negative screws, Phillips for positive screws, and a jeweler's screwdriver set.
Overview of soldering tools including soldering iron for melting solder, soldering tool stand for safety, and desoldering tool for repairs.
Descriptions of splicing tools like long nose pliers for bending wires, side cutters for cutting, and wire strippers for removing insulation.
Explains boring tools including a 12V mini-drill for circuit boards, portable electric drill for chassis, and various types of metal files.
Introduction to cutting tools, specifically the utility knife for various trades and hacksaw for cutting metals.
Introduces auxiliary tools such as magnifying glass for visibility and paint brush for cleaning components.
Overview of electronic equipment including volt-ohm-milliammeter for measurements, oscilloscopes for graphing voltages, and signal generators.
Encouragement for learners to classify various hand tools based on specifications relevant to consumer electronics servicing.
PHILLIPS SCREWDRIVER
is usedto drive or fasten positive slotted
screws. It is a screwdriver that could take
greater torque and could provide tighter
fastenings.
SOLDERING IRON
is adevice for applying heat to melt solder in
attaching two metal parts. A soldering iron is
composed of a heated metal tip and an
insulated handle. For electrical work, wires
are usually soldered to printed circuit boards,
other wires, or small terminals. A low-power
iron (20-30 Watts) is suitable for this work.
9.
SOLDERING TOOL STAND
isa place where the soldering iron is placed
during usage. This will keep the soldering
iron away from flammable materials. The
stand often comes with a sponge used in
cleaning the tip of the soldering iron.
10.
DESOLDERING TOOL
is usedin removing soldered wires and
components on printed circuit boards for
troubleshooting and repair purposes.
LONG NOSE
is usedfor holding, bending, and stretching
the lead of electronic component or
connecting wires.
13.
SIDE CUTTER
is awire-cutting pliers, though they are not
used to grab or turn anything, but are used
to cut wires.
14.
WIRE STRIPPER
is apair of opposing blades much like
scissors or wire cutters. The addition of a
center notch makes it easier to cut the
insulation without cutting the wire.
12V MINI-DRILL
is usedto bore or drill holes in the printed
circuit board (PCB) with sizes from 1/32” –
1/16”.
17.
PORTABLE ELECTRIC DRILL
isused for boring hole(s) in plastic or metal
chassis with the use of drill bits having
sizes from 1/6” to approximately 1/4”.
18.
METAL FILES
These arehand tools having a series of sharp, parallel
ridges or teeth. Most files have a narrow, pointed
tang at one end to which a handle can be fitted.
Flat File is
parallel in
width and
tapered in
thickness;
they are
used for
flat
surfaces
and edges.
Half Round
File is
tapered in
width and
thickness,
coming to
a point,
and
is narrower
than a
standard
half round
and used
for filing
Round File - is
also called rat-
tail file which
is gradually
tapered and
used for many
tasks that
require a round
tool, such as
enlarging round
holes or cutting
a scalloped
edge.
UTILITY KNIFE
is acommon tool used in cutting various
trades and crafts for a variety of purposes.
21.
HACKSAW
is used forcutting metals. Some have pistol
grips which keep the hacksaw firm and
easy to grip. The small hand-held
hacksaws consist of a metal arch with a
handle that fits around a narrow, rigid
blade.
MAGNIFYING GLASS
is aconvex lens which is used to produce a
magnified image of an object. The lens is usually
mounted on a frame with a handle. Roger Bacon
is the original inventor of the magnifying glass. A
magnifying glass works by creating a magnified
virtual image of an object behind the lens. Some
magnifying glasses are foldable with built-in
light.
24.
PAINT BRUSH
is atype of brush made of bristles set in
handle, used for cleaning dirty parts of a
circuit or an object aside from using it for
painting.
VOLT-OHM-MILLIAMMETER
It is anequipment that combines three
functions: as a voltmeter that measures both
ac and dc voltages; an ohmmeter that
measures resistance; and milliammeter that
measures small amount of dc current.a
27.
OSCILLOSCOPE
An oscilloscope (commonlyabbreviated CRO, for
cathode-ray oscilloscope, or scope) is a piece of
electronic test equipment that allows signal
voltages to be viewed, usually as a two
dimensional graph of one or more electrical
potential differences (vertical axis) plotted as a
function of time or of some other voltage
(horizontal axis).
