A training & workshop program on "Circuit & PCB designing "

A training & workshop program on "Circuit & PCB designing " was conducted for Electronics & communication and Electrical department students on 17th February, 2017. The whole program was organized by "TechnoVentures - A technical club of students", Parul Polytechnic Institute in association with "Parul Mozilla club". The technical session was taken by Mr. Viral Patel , Lecturer, EC Department, Parul Polytechnic Institute. The lab(practical )session was conducted by 2 students of EC Department, Mr. Mayank Ramani (Ec 6th sem) & Mr. Ishwariy Joshi (EC 4th sem).


Printed Circuit Boards Basics

PCB’s are the backbone of any production level electronic device in today market, and therefore

knowledge of PCB layout tools can be a vital skill. Both analog and digital circuits are used in PCBs

depending on the application, and with different types of circuits, the designer must take into account

certain design considerations. This guide will show you how to make a simple PCB layout with digital

components, and the design considerations that come with it. More Advance circuits like RF circuits or

Power circuits take more thought in the layout and design because the circuit is more sensitive to

component placement and the lengths of the connections between them.

A theoretical session was taken by Mr. Viral Patel, Lecturer, Parul polytechnic Institute


Topics to be covered under each session was pre-planned by the technical team and followed

accordingly. Overview of which is as follows :

Session Primary learning Details

1 Introduction of PCB design software PCB is a thin (usually 0,5-3 mm) board made of fiberglass, composite epoxy, or other laminate material. Conductive pathways are etched or printed onto board, connecting different electronic components on the PCB. There are single sided (one copper layer), double sided (two copper layers) or multi-layer up to 10+ layers PCBs. Beside the conductive layer most PCBs contains solder mask layers (a thin lacquer-like layer of polymer that is usually applied to prevent solder bridges between closely spaced solder pads) and silk screen layers (displaying text information for soldering or application).

2 Different tools used for PCB designing Schematic design creation, Schematic design capture Determination of PCB template, card dimensions, heat sinks, and fixed components, Deciding on PCB stack layers Line impedance determination, Component placement Signal traces routing, Gerber file generation

3 Circuit design using software tools There are a variety of tools and software that are used to complete this process precisely and efficiently. Electronic Design Automation Tool (ECAD): This is a category of design tools that is used for schematic design capture. They work together in modular design flows to produce design descriptions. Some of the most popular tools that come within this category are mentioned below. ORCAD: This software is used by the design engineers to create the electronic schematics and prints. EAGLE: Easily Applicable Graphical Layout Editor or EAGLE is a solution driven PCB design program. It contains schematic capture editor, PCB layout editor, auto router, and Bill of Materials Tools (BOM).

4 PCB Fabrication as per design input PCBs are typically fabricated in about 22 steps, many of which are digitally controlled and require dedicated data modules called production tools. Some designers believe that their PCB fabrication data will drive the fabricator's production machines directly; that the Gerber files will be used directly on the PCB fabricator's photoplotter; that Excellon drill files will go straight onto the fabricator's drilling machines; and that IPC-D-356A netlist will go right into electrical test machines.

5 Testing PCB after loading components Resistor, Capacitor, Diodes are main tools for testing PCB design circuit after loading components


Some Glimpse :

The practical session was taken by 2 students of EC Department, Ishwariya Joshi & Mayank Ramani.


We are thankful to our Principal Prof. Jatin Vaidya given an opportunity for organizing workshop.

Our special thanks to Mr. Viral Patel, given guidance for doing this type of workshop on PCB design.
