Abstract

Etching is a subtractive method that is used for the production of printed circuit boards (PCBs), where acid is been used to remove unwanted copper from a prefabricated laminate [1]. The manual method of doing this can only be used for a small number of boards and is likely to be messy [2]. Besides this, exposure to some certain kinds of etchants may have adverse effects on one’s health. On the other hand, the machines available to do this provide a cleaner and faster means and can etch many boards at a time but they are very expensive. This usually discourages their purchase among small scale Printed Circuit Board (PCB) manufacturers. But the automated etching system presented here aims at providing a method of carrying out the etching process for a PCB board in a simple, clean, safe and cost effective way. The printed circuit board is mechanically designed to support and electrically to connect electronic components using conductive tracks, pads and features etched from copper sheets laminated onto a non-conductive substrate
