Method for inspection of printed circuit board, involves testing reference image of proper printed circuit board and test image of printed circuit board, and reference printed circuit board and memory of image are digitally scanned

摘要

The method involves testing a reference image of a proper printed circuit board and a test image of the printed circuit board. The reference printed circuit board and memory of the image are digitally scanned. The printed circuit board, which is tested, and memory of the test image are digitally scanned. The reference image is compared with the test image and the ranges with differences in the two images are determined. The alternation of the reference image and the compared image is represented on an indicator. An independent claim is also included for a device for inspection of a printed circuit board.
