Abstract: This research automates the etching process which includes light exposition, developing, and etching processes for a pre-sensitized PCB for board sizes ranging from 2” by 4” to 6” by 4”. It integrates a CNC Laser with the developing and etching processes to provide fast, accurate, and reliable etching. Applied-Quantitative type of research was used, which aims to ease the complexity of manual etching while providing better etching experience by comparing data acquired for both type of process. To assure the effectiveness and efficiency of the machine, Speed, Accuracy, and Reliability tests were conducted. The machine was proven accurate and reliable after 8 out of 9 boards passed the continuity test. This paper also contains tables that compares the time consumed using the automated PCB machine and the manual etching.
