The patented technology control system of Z axis AOI can inspect component side of PTH technology. Simpler debugging algorithm, make the programming easier and easy to learn. shift of two sides of board (components top and bottom), auto software origin emendation. Applied for mark point emendation for duplicated boards &barcode database and PCB bad mark recognition. Creative OCR (Optical Character Recognition) function extends the area of AOI algorithm improves the judgment of mis-placement. Share date among AOI internal network. Effectively focus on SMT and PTH plug-in testing Multifunctionality Multi-functional Precision High-precision High Efficiency Efficient
