ABSTRACT:
An apparatus 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 a 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 the electronic component leads through a different optical route and calculating the amount of deviation in position of the leads of an electronic component in accordance with the picture data obtained by both images, in order to correct the deviation.
