Integrated Application for Technology Construction of PCBs by CNC and Automatic Surface Adjustment

Abstract

One of the biggest problems facing students of the electromechanical majors at Unitec is to produce their own printed circuit boards (PCBs) accurately and safely. Currently students use the etching and ink transfer technique to build the prototypes they use in their circuits and electronic classes. However, this technique despite being easy to apply, is long and tedious, produces boards with defects (when the tracks are thin) and is dangerous due to the utilized acid which is harmful to health and the environment. Through this project, an integrated computer system was created which allows the use of a CNC machine to produce circuit boards. Such an approach allows the height of the board to be considered more quickly, while incurring fewer manufacturing defects and avoiding the endagerment of the health of users and the pollution of the environment with harmful acids.
