DEPARTMENT OF ELECTRONICS ENGINEERING
WORKSHOPS
OBJECTIVES:
Workshop practice is the backbone of the real industrial environment which helps to develop and enhance relevant technical hand skills required by an engineer working in the various engineering industries and workshops.
Our workshop intends to impart basic knowledge of various software tools, components, modules, datasheets and equipment to visualize the outputs and their use in different sections of manufacturing. Irrespective of branch, the use of workshop practices in day to day industrial as well domestic life helps to dissolve the real-life problems. The workshop experiences would help to build the understanding of the complexity of the industrial job, along with time and skills requirements of the job.
Workshop curriculum builds the hands-on experiences which would help to learn manufacturing processes, research as well as repair and production technology courses in successive semesters. Workshop practice is also important since only practice can make the man perfect. The students are advised to undergo each skill experience with remembrance, understanding and application with special emphasis on attitude of enquiry to know why and how for the various instructions and practices imparted to them in each shop. Electronics engineering department has established seven instruction shops to learn and practices wide range of manufacturing processes such as circuits designing, pcb designing fabrication as well as circuit testing on software as well as on breadboard. A resource in the workshop not only helps to complete engineering syllabus practical but also supports to undertake various under graduate projects, creative competitive working models manufacturing to the research projects of social and industrial relevance.
Purpose of Workshops:
· Enriching engineering practices by learning while doing.
· To provide under safe environment, knowledge and practice of various electronics Modules like raspberry pi, Arduino, Wi-Fi modules, Blue-tooth, IR, GSM, GPS sensor modules etc., power tools like Power supplies drill machines grinders, ICs, machine tools like soldering iron, multimeter and measuring instruments like Digital oscilloscope, vector analyser, Spectrum analyser to impart skills to design, measure and control size and shape of engineering products.
· To encourage students to use their knowledge, creativity and skills to design and manufacture solutions of social or industrial relevance.

Safety Measures in Workshops: -
In the Electronics department all the workshops are well fledged with proper safety measures.
Safety measures in various workshops are as follows:
1.Fire Extinguisher is available
2.Earthling for Equipment & Panels is done
3.Do’s and don’ts & safety measures are displayed in the workshops / lab
4.Well trained staff monitors the workshops all the time
5.Periodical calibration of workshop / lab equipment is regularly done.
6.Always power down the electrical equipment, disconnect the power cord, and wait for a few seconds before touching exposed wires.
7.Not allowed to wear rings, watches, necklace, and any other loose metallic objects. Rings and watches are especially dangerous as the skin beneath them is wet by sweat, making the resistance of skin much lower.
8.There must be at least two (2) people in the laboratory while working on live circuits.
9.One tool that requires special attention is the soldering iron. Careless use can result in painful burns and fire. Always put the hot iron in its holder. Turn the iron ON only when you need to use it and turn it OFF when you are done (even if you may need it in 5 minutes). The short warm-up time is a small price to pay for the prevention of potential fire and burn hazards.
10. Make sure that your hands are dry. Resistance of wet skin is 1KΩ as compared to dry skin which is about 500 KΩ.
11.Make sure that your shoes are dry. Do not lean on metallic objects (like legs of tables) as you are providing a very large contact area for the current to flow out of your body to ground. Shoes must be worn at all times.
12.In case of electric shock, cut the power, remove the victim quickly without endangering yourself. If the power switch is not readily available (remember the Lab Emergency Shut-Off Power switch near the door), use an insulting material such as dry wood, rope, belt, etc. The resistance of body decreases during a shock so action should not be delayed. Send someone to call for help immediately.
13.If the victim is unconscious and has stopped breathing, start artificial respiration at once. Do not stop until a medical authority has arrived and taken over. Do not stop even if the victim does not have a pulse.
14.Use only one hand for measurement. No part of a live circuit should be touched by the bare-hand.
15.Keep the body, or any part of it, out of the circuit. Where interconnecting wires and cables are involved, they should be arranged so people will not trip over them.
16.Be as neat a possible. Keep the work area and workbench clear of items not used in the experiment.
17.Always see that the power switch is OFF before plugging into or out-of the outlet. Turn instrument/equipment OFF before unplugging from the outlet. When unplugging a power cord, pull on the plug, not on the cable.
18.No ungrounded electrical/electronic apparatus is to be used in the laboratory unless it is double insulated or battery operated. Keep fluids, chemicals, and heat away from instruments and circuits.
19.Report any damages to equipment, hazards, and potential hazards to the laboratory instructor.
20.The amount of the current flowing through the body during an electric shock depends on the voltage and the resistance between the terminals of the voltage source. This resistance consists of resistance of the contact point between body and circuit, Skin resistance at the point the current flows into and out of the body & internal resistance of body. Larger the resistance, the smaller would be the current.
The ever-present hazard in an electronics Lab is the electric shock. Myth that a 1,000-V shock is deadlier than a 100-V shock is not true. The real measure of a shock is the amount of current that flows through the body.
Impact of ac (alternating) current on the body:
Current |
Effect |
1 - 5 mA |
Threshold of sensation |
5 - 20 mA |
Involuntary muscle contraction ("can't-let-go") |
20 - 100 mA |
Pain, breathing difficulties |
100 - 300 mA |
Ventricular fibrillations (changes in heart beat), death |
> 300 mA |
Respiratory paralysis, burns, unconsciousness |
|
|
Additional Lab Safety Rules:
i. Each group is responsible for their Lab bench. After the Lab exercise is over, all equipment should be powered down and all probes, cords, etc. returned to their proper position. Do not cut and drop wires on the Lab bench which could cause short circuits. Your Lab grade will be affected if your bench is not tidy when you leave the Lab.
ii. No open eatables/food is allowed in the Labs/Workshops on Lab benches.
iii. Always be familiar with the Lab itself i.e. location of mains power switch, fire extinguishers, the emergency exits and nearest phone to call for help.
