Product Description


High Precision 355nm 3W UV Laser Marking Machine QR/Bar Code Testing For PCB Board




QA-AUV3 CNC PCB Board Laser Marking and Testing Machine equiped with a 3W UV laser source, which is suitable to be absorbed by many kinds of materials. So the marking is much more precision and nicer than green laser or fiber laser. The wavelength is 355nm, so it also can do 3D inner engraving on crystal and glass as green laser . 

This system is customized with CNC control, auto uploading and downloading the PCB boards. It will mark QR or Bar code on the PCB board, then use scanner gun to test if the code can be read.
