PURPOSE:To effect soldering with high accuracy by using a laser light after performing the position correction by the signal from the CCD camera arranged at the upper part of a lead as well as preheating a board by the projecting light from the light source provided at the lower part of a moving base. CONSTITUTION:The light emitted from a light source 8 is projected on a circuit board 3 via a lens 9. The transmission light emitted from the part between pads 4 is observed by a CCD camera 14 and a controller 15 is actuated based on the signal from the camera 14 to correct the dislocation of a pad from the lead 6 located by a pin 7 by driving a motor 2. Thereafter, soldering is effected by projecting a laser light. With the device of this composition, the quality and efficiency are improved. |
