Abstract

The machine in drawing 1 is used in the manufacture of printed circuits where a large number of printed circuit lines is required, formed of relatively few different patterns. Image mask 1 of opaque material with the patterns cut as slots 2 necessary to produce the printed circuit as in drawing 2. Mask 1 is mounted on frame 3, drawing 1, so that each aperture in mask 1 is provided with an individual light source 4. Frame 3 is supported by assembly 5 and is capable of vertical movement. Photosensitive plate 6 is positioned beneath mask 1 on table 7 capable of incremental movement in the direction of arrow 8. Movement of table 7 is monitored by a computer, not shown, which selectively controls the energization of light sources 4 to expose plate 6 in the desired printed circuit line pattern.

The machine in drawing 1 is used in the manufacture of printed circuits where a large number of printed circuit lines is required, formed of relatively few different patterns. Image mask 1 of opaque material with the patterns cut as slots 2 necessary to produce the printed circuit as in drawing 2. Mask 1 is mounted on frame 3, drawing 1, so that each aperture in mask 1 is provided with an individual light source 4. Frame 3 is supported by assembly 5 and is capable of vertical movement. Photosensitive plate 6 is positioned beneath mask 1 on table 7 capable of incremental movement in the direction of arrow 8. Movement of table 7 is monitored by a computer, not shown, which selectively controls the energization of light sources 4 to expose plate 6 in the desired printed circuit line pattern. Frame 3 is lowered to bring mask 1 close to the photosensitive surface of plate 6 during operation.
