For the ovens you run the profiler and you compare graphs. For the AOI you should run these golden boards(boards that you keep for AOI test - might have intentionally implemented defects) once in a while and make sure you are getting the same results

Paul, I work for a supplier of 2D and 3D x-ray inspection systems. If you are interested in discussing alternatives to AOI for post reflow SMT process monitoring and inspection I would be happy to discuss several strategy considerrations with you. W

As always, our good colleague Evtimov is right about the AOI and oven. For the AOI you need to make a golden sample board(panel) and test if your machine can catch all defects that you simulated BEFORE the oven. Try to me as accurate to real defects

I am looking for advice on sourcing a x,y digitizer to create pick and place files, off-line, rather than programming with the machine. I could use original gerber data or create the placement coordinates with the digitizer. Also, references to equip

Thanks for your feedback. May you give me an advise if it is better to use X ray inspection intead of optical inspection if we don't have 0201 and 0402 components?

Hi: I am doing a research to compare the a new high resolution digital color inspection system with other technologies in the market. May someone give me a feedback about which equipment and technology is the best?. Thanks

David, I can say this we have 2 vision systems Orbotech and Omron. Both working OK but there is a problem with both....They find a solderballs in board and there is no solderballs! Otherwise can not tell what is a best system. Regards, MadReind

Agilent has a great article on determining whether automated optical inspection (AOI) or automated x-ray inspection (AXI) is right for you. It's a PDF file that can found here: http://www.ate.agilent.com/EMT/LIBRARY/X-RAY/DOCS/59883661en.pdf To sum

I am not a fan of "Gold Board" type of inspection. There are many new sophisticated ways of inspection one being neural networking. This is a method where learning occurs by exposure to a truthed set of inputs and outputs data where the algorythim in
