摘要
PURPOSE: To obtain an external appearance inspection apparatus which can improve the inspection precision of external appearance inspection while eliminating dead angle of laser light and carry out external appearance inspection of soldering condition even if a chip is mounted on a substrate at any rotary angle. ;CONSTITUTION: A laser apparatus 4 to radiate laser light 6 to a substrate 5 from upper side, an optical device 8 to convert the laser light 6 into fan-shaped slit light 6a, and an optical device 11 to convert the fan-shaped light 6a again into slit lights 6b in parallel are provided. Further, a camera 12 to observe the reflected lights 6c of the slit lights 6b in parallel radiated to the substrate 5 from diagonal upper side and a driving means 15 to horizontally rotate the laser apparatus 4 and the camera integrally are provided and thus an soldering condition's external appearance-apparatus is composed for inspecting external appearance in soldered condition.;COPYRIGHT: (C)1993,JPO&Japio
