Abstract
Current technology has established laser scanning systems capable of writing high resolution, large-format images. Recent developments have extended this capability to computer-synthesized images. A system known as a Laser Pattern Generator (LPG) has been manufactured using this technology to precisely image printed circuit board (PCB) masters. Exposure time for an image area of eighteen by twenty-four inches is reduced to two minutes from about five hours for the present vectorized plotter method.
