LIGHT EXPOSURE ASSEMBLY OF A DOUBLE-SIDED PRINTED CIRCUIT BOARD AND INSTALLATION COMPRISING AT LEAST ONE SUCH EXPOSURE ASSEMBLY

摘要

The invention relates to an exposure assembly and a light exposure installation of a double-sided printed circuit board through a first and a second plate, comprising at least one exposure assembly having a frame (14), a first (10) and a second cliché support (16), reconciliation / spacing means (51) for the cliché supports (10, 16), and means for holding the printed circuit board. The installation further comprises optical detection means for detecting position errors, a light source, and optical means for directing a light beam emitted by said light source. The exposure assembly also comprises displacement means. joint (12, 18, 20, 22, 24, 26, 28, 30A, 32A, 32B, 34, 36, 40, 42) for jointly moving the plate supports (10, 16), and separate moving means (18, 20, 22, 24, 26, 28, 30A, 32A, 32B, 36, 38, 42, 44) for moving the second cliché support (16) relative to the first cliché support (10). / P
