LT A680 offline pcb aoi machine
Application process:After stencil printing, after/before hot air reflow
Can test both sides and multiple PCBs simultaneously

The LT A680 offline AOI equipment can detect the high components on the component surface and the SMD components after reflow, and can effectively solve the detection requirements of the tinplate process, and can find the product defects with high precision. , The best choice for process requirements such as SMT reflow and component surface.

Since the brightness and position tolerances of the entire image can be corrected in real time like the online machine, it has the same stability and repeatability as the online machine. In addition, through the combination of rich algorithms and lighting, product defects can be detected with high precision.
