Recently, the most popular method to manufacture elecric circuit patterns on PCB is photolithography. This method is useless, if density of interconnections on PCB goes below 120 um/120 um (track/space width). Laser Direct Imaging method is a solution, in case of higher density of interconnetions on PCB. This article describes design of prototype system for Laser Direct Imaging. (Laser system for direct imaging of high density interconnects on PCB). Slowa kluczowe: Plytki drukowane (PCB), wysoka gestośc upakowania ściezek elektrycznych, fotopolimery, laser UV, naświetlania laserowe.
