You definitely need to have live demos of each system, using your specific assembly if you want to compare apples to apples. Each of the AOI OEM's you mentioned have plus amd minus to their unique systems. You will need to evaluate your specific nee

Start with a definition of what you expect the AOI to achieve at each station. Will your in-line machine be post print? Place (pre-reflow) or post reflow? Rather than buy one very expensive machine to put at the end of the line, maybe a couple of
