Abstract

PURPOSE: To always stably inspect positional shift, by performing imaging so that the light cutting line projected on a substrate and a mounting chip component becomes horizontal in an image and analyzing the shape of the light cutting line in the image to detect the positional shift of the chip component.
CONSTITUTION: A printed circuit board having a chip component being an object to be inspected mounted thereon is mounted on an XY stage 5 and two slit light projectors 3 are arranged so that the light cutting lines allowed to irradiate the printed circuit board cross each other at a right angle. Further, the galvano mirror 4 controlled by an image processing control apparatus 8 is provided in order to control the irradiation positions of the projected slit light beams by reflecting said light. Then, two light cutting lines allowed to irradiate the printed circuit board are imaged in the horizontal direction within an image by two television cameras 1 and a half mirror 2. The shapes of the light cutting lines in the image are analyzed by the image processing control apparatus 8 to detect the positional shift of the chip component.
