Laser Direct Imager(LDI) that is capable of writing Print Wired Board(PWB) and Plasma Display Panel(PDP) patterns directly on work boards has been developed. Conventionally, PWB and PDP are manufactured by (1) making a photo mask of the original data pattern in a computer with a laser photo plotter and (2) copying the photo mask pattern onto a work board or panel by usually utilizing a UV exposure method. LDI, however, writes the patterns directly from the original data in the computer onto the work board or panel, thus revolutionizing the manufacturing process especially by eliminating the photo mask. In this paper, several key features of LDI are described.
