(一)前言电子计算机、电子技术的发展和广泛应用,向人们提出了应用计算技术为计算机及其他电子设备的生产过程服务的问题。数控3机就是在这方面的初步尝试。电子计算机和某些大型电子设备都使用了大量的印制板——印制插件板、印制底板。例如一台大型的电子计算机可能有几百种不同类型的印制板,每种印制板又包括多层印制电路,而每层印制电路的生产都要求人们根据逻辑图(或电路图)进行工程布线、描图(或贴图,下略)和感光照相,以形成印制电路的感光底片,供制板过程使用。可以想像成百种印制板的多层电路的布线、描图和照相需要投入大量的人力、物力和时间,因此,印制电路生产的自动化就成为刻不容缓的了;另一方面,印制电路的日益复杂和不断
(I) Preface The development and widespread application of electronic computers and electronic technologies have raised the question of using computer technology to serve the production process of computers and other electronic devices. CNC 3 machine is the first attempt in this area. Computers and some large electronic devices use a large number of printed boards - printed boards, printed boards. For example, a large electronic computer may have hundreds of different types of printed boards, each printed circuit board also includes multi-layer printed circuit, and each layer of printed circuit production requires people according to the logic diagram (or circuit diagram) Engineering wiring, tracing (or map, slightly below) and photographic camera to form a printed circuit photosensitive film for board making process. It is conceivable that laying out, drawing and photographing a multilayer circuit of a hundred types of printed boards requires a lot of manpower, material resources and time so that automation of printed circuit production becomes an urgent task. On the other hand, Increasingly complex and continuous
