According to the present invention, provided is an ultrahigh-resolution high-speed parallel processing auto-inspection apparatus for a high-integration printed circuit board. The ultrahigh-resolution high-speed parallel processing auto-inspection apparatus includes: a line scan camera for obtaining a surface image of an inspection surface of a PCB; a lighting part emitting light to the inspection surface of the PCB; a vertical movement member supporting the line scan camera to be vertically moved; a laser displacement sensor obtaining inclination information of the inspection surface by pre-scanning the inspection surface of the PCB before obtaining the surface image of the inspection surface of the PCB, and then, measuring the distance between the line scan camera and the inspection surface of the PCB in real time to keep the distance therebetween during the procedure of obtaining the surface image; and a displacement compensation means pre-controlling the movement of the vertical movement member by referring to the inclination information pre-obtained during the procedure of obtaining the surface image, and then, controlling the movement of the vertical movement member to compensate for displacement corresponding to a difference value if there is a change in the displacement measured by the laser displacement sensor. Therefore, the apparatus is capable of enabling quick and accurate defect detection from a PCB.;COPYRIGHT KIPO 2020
