Abstract: The invention relates to an exposure machine for printed circuit panels. The machine comprises: a support (26) for said panel (24); a moving artwork support (10) comprising a substantially rectangular frame (12) and a transparent plate (14) suitable for receiving said artwork; means (22) for establishing peripheral sealing; means for establishing suction in the volume; at least one deformable leaktight balloon (30, 32) disposed between said support and said transparent plate around at least a portion of said panel; and a source of gas under pressure at a pressure greater than the pressure of said suction for the purpose of feeding said balloon, thus that when suction is established in said volume, the periphery of said transparent plate presses against said balloon.

Abstract: The invention provides apparatus for exposing a face of a panel, in particular a printed circuit panel, the device including a light source. The device further comprising: two moving shutters suitable for masking said light source, each of said shutters presenting a respective edge, said edges together defining a window through which a light zone is generated on said face of the panel to be exposed; means for displacing said shutters in a plane lying between said light source and said panel; and control means for controlling the displacement of said shutters in such a manner that both shutters move past said face of the panel at substantially the same speed and in the same direction.

Abstract: An apparatus for exposing a light sensitive surface (e.g., a printed circuit board) to light. An optical processor subsystem, which includes a reflector and an integrator-collimator assembly, processes light from a light source to produce a uniform and collimated light beam having a mean angle of incidence relative to the light sensitive surface of less than or equal to 2° and having illumination uniformity that departs by less than ±10% from a mean value. An optical light shaper subsystem transforms the uniform and collimated light beam into a uniform and collimated light strip. A displacement mechanism provides relative movement between the light strip and the light sensitive surface. A speed matching mechanism matches the speed of relative displacement to the brightness of the light strip and to the sensitivity of the light sensitive surface. The light source remains stationary in one construction and moves relative to the light sensitive panel in another construction.
