5. International Presences:

6. Industrial Visit
 An Industrial visit gives awareness about how an industry actually works.
 Omega has basically the following sections:
1) Research & Development
2) Equipment Testing
3) Soldering and Desoldering
4) Winding section
5) Paint section

7. 1)Basic Electronics:
 The theory of basic electronic device includes introduction of
1) Electronic devices,
2) Components,
3) Circuits,
4) Working,
5) Characteristics,
6) Assembling
7) Applications
8)Advancements and future aspects

8. 2)PCB Designing and fabrication Process:
 Soldering is an essential part of PCB Fabrication.
 Soldering is a process in which two or more metal items are joined together
by melting and flowing a filler metal (solder) into the joint, the filler metal
having a lower melting point than the adjoining metal.

9. Steps in PCB design
1. Film Generation
2. Shear Raw Material
3. Drill Holes Industry standard
0.059" thick, copper
clad, two sides

10. Steps in PCB design
4. Electrolus copper
Apply copper in hole barrels
5. Apply Image
Apply Photosensitive Material to
develop selected areas from
panel

11. Steps in PCB Design
6. Strip and Etch
•Remove dryfilm, then
etch exposed copper
•Tin protects the copper
circuitry from being
etched
7. Solder Mask
Apply solder mask area to
entire board with the exception
of solder pads

12. Surface Mount
Technique:-
 Surface mount technology (SMT) is a method for
constructing electronic circuits in which the components
(SMC, or Surface Mounted Components) are mounted
directly onto the surface of printed circuit board (PCBs).
 Electronic devices so made are called surface mount
devices or SMDs.
 In the industry it has largely replaced the through hole
technology construction method of fitting
components with wire leads into holes in the circuit board.

13. 3)Introduction of Robotics:

14. What is Robotics:
• -It is a field of Engineering that covers the mimicking of human behavior.
• -Robotics includes the knowledge of Mechanical, Electronics, Electrical & Computer
Science Engineering.

15. Why Robotics:
• -Speed.
• -It can work hazardous/dangerous
environment.
• -To perform repetitive task.
• -Efficiency
• -Accuracy

16. Types of Robots:
• -Wheeled
• -Legged
• -Climbing
• -Flying

17. Power Supply:
• -Suitable power supply is needed to run the motors and
associated circuitry
• -Typical power requirement ranges from 3V to 24V DC
• 220V AC supply must be modified to suit the needs of our
machine
• -Batteries can also be used to run robots
• -Robots are driven by different motors :-
o DC Motors
o Stepper Motors
o Servo Motors
