Abstract
PURPOSE:To detect the shape of a solder connection part at a high speed by checking the distortion extent of the shape of a light pattern obtained through single-time image pickup operation by the solder shape detecting device. CONSTITUTION:Multiple circular laser light 30 which is converged on a printed circuit board 7 at right angles to the solder connection part 4 by a beam splitter 32 is reflected by the solder connection part 4 and transmitted through the beam splitter 32 to illuminate the light pattern image forming lens 51 of a light pattern detecting means 5. Then the light pattern converged by this lens 51 is picked up by an ITV camera 52 and converted into an electric signal, which is supplied to a microcomputer system 53 and a monitor 54. Here, the monitor 54 displays the light pattern 40 of the solder connection part 4 and a microcomputer system 53 judges whether or not the shape of the solder connection part 4 is normal from the light pattern 40.
