Report of PCB Designing Workshop-IETE FORTNIGHT 2019
Title: PCB Designing Workshop
Date: 3rd February 2019
Number of students participated: 10
Year: F.E. & S.E.
The PCB designing workshop held on 3rd February, 2019 was conducted by our IETE-SF’s very own technical head, Muddassir Shaikh. He has an experience of two years in handling technical aspects of our IETE Committee.
First things first, the students had to install the Altium Designing Software. Muddassir familiarized the students with the basics of the software and taught them how to operate the functions in a very synchronized and easy manner. Altium Design is a PCB and electronic design automation software package for Printed Circuit Boards. The students had hands on experience of the software by designing a PCB for an automatic vehicle sensing street lamp. Designing PCB on the software was a straightforward method by using drag-drop and joining the points methodologies.
The students were then familiarized with the more technical aspects of the PCB Designing : scrubbing, ironing, etching, drilling and soldering. Once the students had taken a digital printout of the software designed PCB, the printout has to be cut and placed on the shining copper board. Ironing is the process of supplying heat to the digital printout and the copper board together such that the print into sticks on the board when the paper is peeled off. Once the PCB’ s were ironed, Muddassir explained the students the important process of etching of PCB. The circuit board are dipped into a chemical which removes the unnecessary copper from the circuit board. Etching helps in better circuit efficiency as there are now minimal chances of short circuiting. Once the layout is ready on the circuit board, holes are drilled using a hand drill where the component wires can be placed in order to complete the circuit. The technical volunteers helped the students to get the components in the correct position for soldering.
Soldering was the most delicate and critical part of the PCB designing. It joined the circuit board and the components with heat and soldering wire.
The PCB was finally ready to work. When batteries were attached it worked as a automatic street light based on a LDR sensor. The students were given assignments to practice what they learnt in the workshop.
