There are several strategies in testing an electronic components

2. What are Passive 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.

3. Circuit Symbols of Active and Passive Electronic
Components
Electronic components,
both active and passive,
are lifeline of any Printed
Circuit Board assembly.
They both play vital roles
in the functioning of any
electronic device.
Electronic Components
are intended to be
connected together,
usually by soldering to a
printed circuit board
(PCB), to create an
electronic circuit with a
particular function.

4. Dynamic Testing
• Electronics tests place a wide range of performance demands on test
equipment for static and dynamic test equipment. The equipment is
used to validate new designs, improve manufacturing processes and
prove the quality of end products. Mechanical testing requirements
involve static, dynamic and fatigue testing in tensile, compression,
shear test modes.
• Testing the mechanical endurance and integrity of electronics
components and assemblies is important to validate designs, improve
manufacturing, and ensure the reliability of final products.

6. 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.

7. In-circuit test equipment consists of a number of elements:
a. In circuit tester: The in circuit test system consists of a matrix of drivers
and sensors that are used to set up and perform the measurements. There
may be 1000 or more of these driver sensor points. These are normally
taken to a large connector conveniently located on the system
b. Fixture: The in-circuit test system connector interfaces with the second
part of the tester - the fixture. In view of the variety of boards this will be
designed specifically for a particular board, and acts as an interface
between the board and the in circuit tester. It takes the connections for the
driver sensor points and routes them directly to the relevant points on the
board using a "bed of nails".
c. Software : Software is written for each board type that can be tested. It
instructs the test system what tests to perform, between what points and
details of the pass / fail criteria.
