Date of workshop: 28-29 September 2019
DEEN DAYAL UPADHYAYA COLLEGE, DELHI UNIVERSITY
As we see the need for electronics gadgets and devices increasing every day, so it is equally important to implement the solutions. These solutions are made reliable and effective through good designing and fabrication techniques. With such an aim, SINCGRID organised a two-day workshop at DDU college, DU. The educational and technical support was provided by Centre for Electronics Design and Technology, NSUT.
The event began with the inauguration by Dr Hem Chand Jain, Vice Principal of Deen Dayal Upadhyaya College along with the other faculty and Prof. Dhananjay V. Gadre from Netaji Subhas University of Technology (NSUT) formerly known as NSIT. The electronic Inauguration Lamp developed at Centre for Electronics Design and Technology (CEDT, NSUT) was used to inaugurate the event. The event was made possible by the efforts of Prof. Dr Ravinder Kaur, who made all the arrangements of the workshop.
The workshop began with Eagle Tutorial by Arun Kumar from SINCGRID. EAGLE stands for Easily Applicable Graphical Layout Editor and is used for Printed Circuit Board designing with several other applications. Discussion on schematic, layout design along with the industrial application of the software was explained.
Students were equally attentive and several questions were raised by the students which were cleared accordingly. The primary reason for the workshop is to show the potential of practical knowledge in the field of electronics and circuit designing. After the discussion, fabrication started for Digital-Analog colour mixer in which 54 Students of Electronics (Hons.) department from 7 different colleges participated. Students from following colleges attended the workshop:-
- Deen Dayal Upadhyaya College(hosting college)
- Hansraj College
- Bhaskaracharya College
- Shri Venkateshwara College
- Acharya Narendra Dev College
- Atma Ram Sanatan Dharam College
- Khalsa College
After the session on EAGLE tutorial, fabrication process was started. Toner transfer method was used for fabrication of digital-analog colour mixer. Students were informed about the various processes involved in fabrication. The kits were handed over to the students, containing the copper clad, printed layout, cutter, tweezer, etc. Guidelines for the sanding process was conveyed to the students. After sanding pressing activity for the layout started. Removal of paper and etching activity started afterwards. By the end of the day, acrylic spray part was done, so as to prevent the corrosion of copper tracks.
Day 2 began with drilling and soldering of the PCB’s and discussion on the various skills required to perform the remaining steps efficiently. In drilling, there were primarily two drill bits used, size: 0.9mm and 3mm. Most of the students were doing drilling for the first time so there was a lot of misjudgement, but all the errors were resolved. After that soldering was performed, which was a quite fulfilling process. Soldering of various SMD and through-hole components was carried out.
By 17:00 soldering and drilling were completed. Everyone was able to solder their board and get it tested.
Finally, Prof. Dhananjay V. Gadre initiated with the demonstration of the projects based on Embedded Electronics which were made by the students of NSUT. The project demonstration was done to generate a spark in the mind of the students towards practical learning. Overall the workshop conducted was a successful event where student learned the method of PCB fabrication and scope of electronics in problem-solving in human life.
The workshop was made possible by the immense effort of mentors. We would like to thank Aditya, Anjali, Apoorv, Harsh, Harshul, Naman, Neha, Nilesh, Nitish, Raghav, Sumiran, Suprio, Vatsal, Yash for helping out in each and every process. We also thank the electronics department of Deen Dayal Upadhyaya College.
Sincgrid aims to continue its work in the domain of teaching embedded electronics and its different aspects. We want more and more students, hobbyists and tinkerer to learn these practical aspects of working in the embedded field.
