Hello NHTech,
When it came time to invest in AOI, my team and I checked out several machines. We run a wide variety of products and our changeover is high, on the order of five to ten jobs per day. MVP is one of the machines that we looked at, however, we found the programming to be very cumbersome. My take is that MVP would probably be better suited for higher volume applications where programming time is not so critical. Ultimately, we narrowed the selection down to two machines, YESTech and MIRTEC. We had an opportunity to work with both of these machines on our production floor. We found that the MIRTEC machine consistently provided better defect coverage than the competitive system, especially with regard to solder joint inspection. We also ran a very simple Gage R&R test on the two systems. The MIRTEC machine easily won.
The MIRTEC machine was about two and a half times faster with roughly 20% less false calls. Although this did help with my ROI, performance was my main concern. We cannot afford escapes... PERIOD! That's the reason why we needed AOI in the first place!
We now have a total of five MIRTEC machines in production including an MV-7xi system configured with a total of five(5) 5 mega pixel cameras and a high resolution telecentric lens. Solder inpsection on 01005's is not a problem. You should also check out thier Intelli-Scan Laser system option. Totally worth the investment in my opinion.
Good luck with your AOI project.
