Abstract

1,140,976. Programmed electric control systems; projection printing. MARCONI CO. Ltd. July 6, 1967 [Sept.23, 1966], No.42667/66. Headings G2A and G3N. [Also in Division H1] A method of photographically recording a printed circuit or a master photograph for the manufacture thereof comprises photographically recording the circuit layout or photograph on a photo-sensitive surface by a light source which is controlled and moved in co-ordinate directions with respect to the surface by decoded digital signals. The signals may be recorded on a tape which is mounted in a device 11 the output signals from which are fed to known decoders 12-14 which control the light intensity of a light source 7 in an on off manner, and co-ordinate motors 1, 5, to produce a series of spots. The surface may be an insulated board clad with a copper layer over which is a photo-resist coating. A duplicate arrangement may operate on the reverse side of the board. Motors 1, 5 may be of the stepping type. To record letters or indicia e. g. for giving information, a stepping motor (19) Fig. 2 (not shown) controlled by a fourth decoder may coincide a selected one of a plurality of masks (21) on a rotary carrier with the lamp. The arrangement of Fig. 2 may be additional to or form part of that shown in Fig.1.
