Printed Circuit Generator

The programmed machine generates land patterns for making printed circuits.

A sheet or material 1, capable of being exposed photographically, is mounted on scan table 2 which is moved in the x and y directions by motors 3 and 4. The photographic material is, for instance, film or a copper clad card coated with photo-chemicals.

Motors 3 and 4 are energized selectively by program scan control unit 5 into which program information is fed, e. g., from a card reader. Controller 5 is also coupled through pulse amplifier 6 to arc lamp 7 to selectively energize it. Light from lamp 7 is directed by cylindrical mirror 8 through lens 9 to form a spot 10 at the plane of the photographic material 1.

By coordinating the motion of table 2 in the x and y directions with the energization of lamp 7, land patterns for printed circuitry are automatically traced out.
