3. Electronic Burglar Alarm System for Automobiles
The alarm accepts signals from a
variety of sources including special
sensors and the standard switches in a
car such as the door and ignition
contacts. The circuit consists of timers
triggering circuit, delay and control
circuits which provides relay out-put
that
controls an acoustic transponder
(loud speaker or buzzer). A switch is
used for all control functions like
setting alarm, energizing time etc.

4. Transistor Radio Receivers (AM/FM)
A radio receiver consists of a RF section with mixer and oscillator, IF
section with one or two amplifiers, a detector section and AF section with
push-pull amplifier stages and loud speakers. As per the circuit design these
stages are assembled on a printed circuit board using appropriate components
and aligned . It is essential to test the bought-out components prior to
assembly for avoiding any defective component going into the assembly.

5. Public Address Amplifiers
Public Address Amplifiers,
popularly known as sound systems,
find extensive application at public
meetings, social functions,
religious places, schools and
colleges, hotels, elections
auditoria, etc.In this area
considerable expertise has been
built up in the country, particularly
in the small scale sector.
Electronic components such as
resistors, capacitors, diodes, transistors
etc., are mounted on PCB cards. Each
card is tested for gain, distortion,
frequency response etc. All these cards
are mounted in the chassis along with
pre-tested transformer and power supply
cards. The interconnections between the
ODS) like Chlorofluoro Carbon (CFC),
Carbon Tetrachloride, Halons and Methyl
Chloroform etc. need to be phased out
immediately with alternative chemicals/
solvents. A notification for detailed Rules
to regulate ODS phase out under the
Environment Protection Act, 1986 have
been put in place with effect from 19th
July 2000.

6. Power Pack/Battery Eliminators
Battery eliminator is used in place of
ordinary dry batteries as power source
for equipment like radio receivers
AM/FM, tape recorders, calculators etc.
and other low power operated
equipments.
Battery eliminator’s output is DC voltage
which usually varies from 1.5 V / 3 V to
12 Volts / upto 500 mA. This item is
reserved for manufacture in the small
scale sector.

7. Electronic Quartz Analog Clocks
The electronic quartz analog clock has brought a revolution in
the clock industry. The quartz clocks were introduced in the
Indian market in 1977-78 and since then market as well as
production in India has been growing at a tremendous rate.
Some of the main features of the quartz clock are; high accuracy,
no winding required, works in any position, very low power
consumption, hardly any service required and the longer life of
the clock
The Quartz wall clock will be
assembled and for assembly other
raw materials such as quartz clock
movement, Cabinet, hand etc., will
be purchased from the market. In
this project profile, it is assumed that
the complete Quartz movement is
procured from outside. The
movement is fitted into Cabinet case
which is fitted with dial and the
hands are mounted on the
movement and after the glass and
back cover of Cabinet are fitted. The
needles have to be properly fitted at
accurate position on dial which
shows time.
Finally, the battery should be put into
the clocks put for testing for at least
2 days before despatch

8. Personal Computer (Pentium – IV)
Personal Computer hardware consists
of CPU, Memory, Direct memory access,
Peripheral controllers and interfaces,
Floppy disk drives and hard disk drives.
The peripherals consists of Keyboard,
CRT Monitor, Printer, Modem and Mouse
etc. and connected to the main PC
through cables and interfaces. Switched
Mode Power Supply (SMPS) are used to
power the personal computer for
different dc voltage: +5V, -5V, +12V and
-12V. The SMPS is housed in the PC
cabinet . The CRT Monitor and Printer
have their own power supply units

9. CRT Data Display Monitor (Colour
The main PC Board is assembled by
mounting the various active and passive
components. All the mechanical fittings
are fitted to the Cabinet alongwith
Cathode Ray Tube and other controls
and terminations. Printed circuit board
is tested individually with the help of
oscilloscope, multimeter and power
supplies and then fitted into the cabinet.
The wiring is completed for PCB. the final
testing is done with the help of personal
computer and software package for CRT
monitor testing

IT Enabled Services/Cyber Cafe

11. Regulated DC Power Supplies
DC power supplies are used extensively
in various electronics laboratories, industries and
communication departments to feed DC voltage to the
electronic modules, R and D sections, institutions and colleges
to impart practical training etc

12. Desk Top Publishing Centre
DTP is used for type setting, layout,
printing, graphics and photographs .
It has wide applications in designing and
producing newsletter, reports, data
sheets, invitations, certificates,
brochures and catalogues .
With the DTP software package ‘Page Maker’ and
MS-WORD, it is possible to undertake a newsletter,
certificates, data sheets, brochures and catalogues

13. Electronic Gas Lighters
The following BIS
Standards may be
referred:
IS 11514:1985 Piezo
electric ceramic
cartridge for impact
type gas lighters. IS
11519:1985
Piezo electric ceramic
cartridge for squeeze
type of gas lighters. IS

electric ceramic
elements (impact type
and squeeze
type).

14. Computer Keyboards

15. Loud Speakers
Process of Manufacture
The incoming Raw Material and
components are tested for required specifications and made
dust free. The Magnet frame Assembly is done and drying is
done, followed by dust free operation.
The voice coil, spider and the paper cone fixed on the yoke and
basket assembly by using adhesives.
The rubber lining is placed along the edge of the basket. Leads
are taken out to each terminal eyelet. The whole loud
speaker is tested for required specification before despatch.

20. Electronic Weighing Scales
The manufacturing
process involves
the assembly of load
cell, electronic
circuits and electro
mechanical
hardware.
Subsequently, the
electronics
assembly-the ICs,
transistor, diodes,
resistors, capacitors
transformer, coils,
relays, potentiometers
are assembled on
PCBs as per design.

Tele–communication Equipment

22. Electronic Industrial Timers

23. Transformer and Coils
(For Electronic Applications) As mentioned earlier,
Transformer and Coils are used
in almost all electric fields like
Consumer Electronics, Process
Control Instruments, Power
Electronics, Medical
Electronics, Computer,
Industrial Electronics, in
Defense, Telecommunications
to perform various functions.
The total performance of any
electronic equipment depends
on the quality of transformer.
Because of increase in growth
of Electronic industries, the
demand for transformers has
increased

24. TV Tuners
The new entrepreneur has to
manufacture electronic tuners alongwith
mechanical tuners and has to make
marketing tie-up with TV receiver
manufacturers and service centres for
economical availability. Even the kits are
available in pure assembled
components. The production of
mechanical tuner over the last three
years declined due to the Introduction
of electronic tuner. The machinery and
equipment and raw materials required
for manufacture of mechanical tuner is
indigenously available

25. Uninterrupted Power Supply (UPS)
There is a large demand of UPS in the process industries, hospitals, banks, offices, cinema theatres,
airports, railway stations, hotels and computer installations. The computerization in both the
Government and private sector has lead to the growth of UPS market. Besides, UPS growth is also
expected due to price reduction of UPS technological advancement, large replacement market,
deteriorating power situation.

26. Crimped wire connectors
Crimped connectors
fulfill numerous uses,
including termination
of wires to screw
terminals, blade
terminals, ring/spade
terminals, wire splices,
or various
combinations of these.
A tube-shaped
connector with two
crimps for splicing
wires in-line is called a
butt splice connector.
Single-wire crimp
terminals

27. Wire Wound Resistors
Wire wound resistors, which
are used in electronic
equipment and instruments
where high precision and more
power dissipation are specified.
Wire Wound Resistors are
preferred over metal oxide
resistors because of being
better temperature co-efficient
and of smaller size. Again wire
wound resistors can be
divided into silicon coated
ceramic type,
aluminium type etc.,
