We have developed an advanced digital exposure system for the printed circuit board manufacturing industry. This system has DMD based optics combined with 405nm laser units designed using Fuji Film original technology so as to achieve both high productivity and high precision at the same time. Fuji Film has experience packing plural laser modules into a single unit for high power output. The laser source is led into the optical systems through optical fibers. The exposure engine has plural optics covering a width of 510 mm that enables scanning of the panel in a shuttle motion. As a result, the exposure time is only 10 seconds for 510×610mm-sized imaging in the case of 10 mJ sensitivity materials. The system can produce over 160 panels per hour, making it suitable for mass production in the industry.
