ABSTRACT:
A method for the alignment of electronic components to be mounted on a printed board. The alignment is accomplished by illuminating the surface of the printed board to cause emission of fluorescent light from the substrate of the printed board, detecting the fluorescent light by optical means to detect an image of the conductor pattern of the printed board as a negative picture, taking an image of leads of an electronic component by optical means as a positive or negative picture, and correcting the deviation of the leads of the electronic component from the conductor pattern on the basis of picture data obtained from both images.
