1. From your previous lesson, you learned to terminate and connect electrical wires and electronic circuits. This
task can be effective with the use of hand tools and equipment at the same time observing safety measures.
Interminating and connecting electrical wires and electronic circuits you learned the different methods of doing it
which is widely used nowadays in the industry or even in the household. These include:
1. Soldering Process which offers flexibility, durability, and corrosion resistance;
2. Insulation Displacement Connections (IDC) which is probably the fastest way to terminate wires, and
3. Crimping Method which is a solderedless method performed by first inserting the terminal into the crimp tool.

____________________________________
PASSIVE DEVICES = Devices or components which do not require an external source to their operation.
1. RESISTOR - Resistors regulate the amount of current flowing in an electronic circuit. Resistors present a
resistance, or impedance, to the electrical circuit and reduce the amount of current that can flow.
2. CAPACITOR - a two-terminal passive component that is used to store energy. It can be used in a circuit as
smoothing, coupling and bypass component.
3. INDUCTORS - a two-terminal passive component that store energy in the form of magnetic field. It is used in
circuit as “choke” and “reactor” in RF receiver and transmitter circuits.
ACTIVE DEVICES – Devices or components which requires external sources to their operation.
Light Emitting Diode (LED)– is a small component that lights up when current flows through it. Sometimes you
use it for simple tasks like indicating that your circuit has power, that the circuit is working, or that the circuit has
failed.
2 TRANSISTOR- a three-terminal active component that is used mainly in boosting or amplifying electrical signals;
both AF and RF ranges.
3.SWITCH- necessary to turn the electrical circuit “on” or “off”
Criteria for Testing Electronic Components
The criteria for testing electronic components are testing its, controls, Effectiveness, Efficiency, functionality,
performance, reliability, interoperability, operating parameters, and bug detection.

III. Different Methods in Testing an Electronic Components
A. Automated
Testing tools that are capable of executing tests, reporting outcomes and comparing results with earlier test
runs. Tests carried out with these tools can be run repeatedly, at any time of day. The method or process being
used to implement automation is called a test automation framework.
B. Debugging
This is part of the software testing process and is an integral part of the entire software development lifecycle.
The debugging process starts a soon as code is written and continues in successive stages as code is combined
with other units of programming to form a software product.
C. Inspection
2. An organized examination or formal evaluation exercise. In engineering activities inspection involves the
measurements, tests, and gauges applied to certain characteristics regarding an object or activity. It is a test
headed by a person using
procedures, processes, and measurements to meet certain standards or requirements.
D. Platform Testing
This requires a platform or medium. Also called an open test standard (OTS), a set of specifications defining test
methods for diverse components of computer and electronic systems to be marketed as complete products.
E. Prototyping
Releasing a new model or design unit. Testing a prototype allows the designer and client to assess the viability of
a design.
IV. Testing Strategies for Electronic Components
Passive electronic components are those that don’t have the ability to control electric current by means of
another electrical signal. Examples of passive electronic components are capacitors, resistors, inductors,
transformers, and some diodes. These can be either Thru-Hole of SMD Components.
Dynamic Testing
This is a software testing type, which checks the dynamic behavior of the code. In order to check the dynamic
behavior, the code must be executed.
We all know that Testing is verification and validation, and it takes 2 Vs to make testing complete. Out of the 2
Vs, Verification is called a Static testing and the other "V", Validation is known as Dynamic testing.
In-Circuit Testing
In-circuit test equipment provides a useful and efficient form of printed circuit board test by measuring each
component in turn to check that it is in place and of the correct value. As most faults on a board arise out of the
manufacturing process and usually consist of short circuits, open circuits or wrong components, this form of
testing catches most of the problems on a board. These can easily be checked using simple measurements or
resistance, capacitance, and sometimes inductance between two points on the circuit board.
