UV exposure unit for PCB prototyping

Abstract

This paper presents a solution for an electronic printed circuit board (PCB) production device based on a photolithographic production approach. The motivation for the development of such a device form scratch is to make a low cost device suitable for educational facilities. The device is completely automated to simplify its usage. All technical solutions and other assumptions related to this project are confirmed by computer simulations and complete hardware implementation. The article also describes and compares available solutions in terms of light source usage, working area and price.
