Double sided PCB designing and Etching CNC

Project Title

Double sided PCB designing and Etching CNC

Project Area of Specialization Electrical/Electronic EngineeringProject Summary

Our project titled as ’’ Double Sided PCB designing & Etching’’ is an idea in which first we create a file of PCB layout and then this file is converted into G-Code file . A G-Code file contains the x,y,z axis coordinates which is then provided to our  motors through Ardunio that performs the operation and provides the coming data by deciding its direction and speed to motors. The motors then work on the coordinates and move forward and backward and the process will draw the layout which was given to it in the form of G-Code file.

Our idea is to draw this circuit on a PCB sheet with a conductive router which will draw the circuit as layout. This project focuses on the design and implementation of automatic double layer PCB using ARDUINO UNO.

Project Objectives

our main objectives of the project are as follows. 

• Designing the circuit.
• conversion of circuit into coding and coding converted to G-code.
• G-code decoded by arduino uno
• Uno controlling motors and modules.

Project Implementation Method

This project uses hardware and software implementation of a CNC to drawn PCB layout and drill holes

The system consists of a electro-mechanical setup that can move in X, Y and Z directions.

A PCB layout is designed in eagle software.

It is then converted to G-code.The G-code is then transferred to Arduino.

Arduino controls the motors which are connected to it.

Motors and sensors provide feedback to the control unit.

If one side of PCB is completed then the motor will rotate the sheet.

Benefits of the Project

Designing of PCB layout will be easy.

It will be more efficient than making a PCB layout with hand.

Size of PCB sheet will be reduced.

No error of short circuiting.

It will be less time consuming.

Technical Details of Final Deliverable

The hardware system of the project will be submitted alongwith the softwares used.there will be a mechanism which will get a circuit design from the software and will print and etch it on the PCB after that when one side of PCB circuit is completed the mechanism of CNC will rotate the PCB and the printing on the other side will begin.
