Use Basic Electronic Hand Tools
INTRODUCTION
This module contains information and suggested learning activities on Using Basic Electronic Hand Tools. It includes instructions and procedure on how to use basic electronic hand tools.This module consists of three (3) learning outcomes. Each learning outcome contains learning activities supported by instruction sheets. Before you perform the instructions, read the information sheets and answer the self-check and activities provided to ascertain to yourself and your instructor that you have acquired the knowledge necessary to perform the skill portion of the particular learning outcome.
Upon completing this module, report to your instructor for assessment to check your achievement of knowledge and skills requirements of this module. If you pass the assessment, you will be given a certificate of completion.
SUMMARY OF LEARNING OUTCOMES
Upon completion of the module, you should be able to:LO1. identify functional basic electronics hand tools;
LO2. use appropriate basic electronics hand tools based on the safety requirements; and
LO3. maintain basic electronics hand tools.
TECHNICAL TERMS
Active State. It is a condition of a semiconductor device that is
working.
Alternating Current. It is an electric current that is continually
varying in value and reversing its direction of
flow at regular interval.
Anode. It is a positive electrode of semiconductor device.
Biasing Current. It is a current supply needed by the semiconductor
in order to work properly.
Capacitance. It is a property that exits whenever two conductors are
separated by insulating material, permitting the storage
of electricity.
Capacitor. It is a component designed intentionally to have a definite
amount of capacitance.
Cathode. It is a negative electrode of semi-conductor devices.
Circuit. It is an arrangement of one or more complete paths of electron flow.
Conductor. It is a wire, cable, or other body or medium that is suitable for carrying electric current.
Couple. This is to connect two circuits so signals are transferred from one to the other.
Current. It is the rate of transfer of electricity from one point to
another.
Cut-off State. It is a condition of a semiconductor device that is not
working.
DC Milli-Ammeter. It is an instrument that measures the amount of
direct current flow in a component or circuit.
Desoldering. It is a process of unsoldering unwanted parts or
components in the circuit with the support of soldering
tool.
Dielectric Material. It is a material that serves as insulator with poor electric conductivity.
Direct Current. It is an electric current that flows in one direction.
Discrete Components. They are separated components.
Junction. It is a hybrid of an electronic circuit enclosed in a single
package having an output that varies directly proportional
to the input.
Ohmmeter. It is an instrument that measures the amount of
resistance in certain component or circuits.
PCB. It is a Printed Circuit Board or (PCB) which is actually printed
wiring boards that have components inserted into the hole and
soldered to form its circuit connection.
Quiescent Point. It is the least amount of operating current of semi
conductor in order to work properly.
Resistance. It is the opposition that a component or material offers to
the flow current.
Resistor. It is a component designed intentionally to have a definite amount of resistance.
Soldering. It is a process of joining two metals caused by heat
Soldering Technique. It is a right process in which the solder (lead) is being applied in a connection or in the printed circuit board.
Splicing. It is defined as a joint that connect two lengths of conductor.
Voltage. It is the electrical pressure that exist between two points and capable of producing a flow of current when a close circuit is connected between the points.
Voltmeter. It is an instrument that measures the amount of electromotive force in a component or circuit.
