Computer-controlled precision drilling machine

Abstract

Printed circuit boards (PCBs) are probably the most common method of constructing electronic circuits, being widely used in most electrical items, and now a common sight in schools and colleges. However, in industry, all the manufacturing processes are nearly always automated, yet schools rarely have similar facilities. One of these processes, the drilling of the holes in the PCB, is probably the most time-consuming and repetitive of these tasks—one which could easily be automated.
