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

Test Jet will work for catching lifted leads, certainly. X-ray is the only thing for testing for internal solder defects such as voids and cracks. I personally do not have any experience using X-ray, so I cannot advise on its reliability. Perhaps

Dback, Some questions for you: 1. Are you using the red light configuration for better contrast on the 0402 parts? 2. Is your system fitted with both low and High Magnification cameras? Have you spoken with the guys at YESTech? Their phone support i

Dback, Most likely shouldn't have color inspection on. Using red light colors will look the same so you gain nothing by using this. What exactly are you getting as false calls? Sounds like you have lots of things going on in this type of inspect

some things to consider, Is there flux on the board. are there finger prints on the tops of parts. Is the board warped at the V score from reflow Is the board shifting in the machine during inspection. These are the issues we have had with our mir

Programming is different, yes, but so is the terminology. ///with machine vision you have parameters that select what is good and what is bad, and you have parameters that help make bad look worse and good look better making the difference between w
