Application of technology

Imagine that you have the task of producing a printed circuit board that has to be drilled (using a small pillar drill) with 100, or so, 1 mm diameter holes through which component leads are to be inserted prior to soldering in place. In order that the component leads align with the copper pads on the track side of the circuit board, each of the holes has to be precisely positioned. Clearly, this task might take you some time but you would probably get there in the end!
