Abstract
An exposure assembly and an exposure installation for exposing a double-sided printed circuit panel to light through a first and a second artwork, including at least one exposure assembly having a frame, a first and a second artwork support, means for moving closer/separating for the artwork supports, and means for holding the printed circuit panel. The installation furthermore includes an optical detection device for detecting position errors, a light source, and an optical device for directing a light beam emitted by said light source.The exposure assembly furthermore has a common displacement device making it possible to jointly displace the artwork supports, and a separate displacement device making it possible to displace the second artwork support with respect to the first artwork support.
