The inspection of the PCB hole inspection machine is considered a critical test step in the PCB and semiconductor industry. X-ray systems must provide high-resolution, high-magnification, and high-contrast images at different viewing angles, observe and parameterize the PCB positioning holes, check if the holes in the layers are misaligned, Measurement of conditions, including the location of the center of the circle, the distance between the point and the point, the area of the circle, etc., can be determined according to the set parameters.
