ABSTRACT OF THE DISCLOSURE A printed circuit production line, comprising a comput- er connected to an input device and, via an interface, to an automatic laser engraving unit mechanically coupled to a pla- te holder and a printing machine which, in turn, is mechani- cally coupled to a set of equipment for mechanical working and chemical and galvanic treatment of printed circuit boards. The automatic laser engraving unit comprises a plate scanning system and an optic laser system which are optically inter- connected. The interface comprises a switching circuit, an interrogation driver, and a pulse repetition frequency multi- plier. The invention considerably speeds up the manufacture of printed circuits, reduces the amount of rejects, and im- proves the quality of printed circuits and working conditions.
