Automatic printed circuit board imaging system |
摘要 |
A printed circuit board imaging system automatically aligns apertures on a board with reference points established by light beams located outside an exposure unit. The reference points have a known spatial relation to alignment pins in the enclosure. A movable arm engages an aligned board, moves it into the exposure unit and deposits it on the pins.
