Paper Title
PCB Plotter And Retracer

PCB fabrication is a tedious process. Printing of the circuit to the copper board is the most difficult task in PCB fabrication process. There are many tech- niques existing in the PCB printing process. Some of them are screen printing, laser printing, manual printing etc. All these methods have some of the following de- merits such as high cost of production, high requirement of man power, highly time consuming. All these disadvantages can be overcome with the help of our proposed PCB printer. The proposed system uses a robotic arm which helps in plotting the circuit on to the copper board. The robotic arm plots the layout to the board as per the directions given by the controller. The proposed system also makes retracing of the circuit from the PCB possible. This is made possible by moving the robotic arm above the circuit and tracking each point in the circuit.
