Assuming you want to run 8 hours a day and 5 days a week, you need a sustained throughput of 2.5k components per hour. With fine pitch, futzing around, setup, etc you should really look for machines rated in the 4k to 5k per hour range. That's not sc

Hello Sibbe, Thank you for posting your questions. There are a few approaches to AOI with the majority being program driven. There are a couple of systems that are simply comparative in that you use the system to compare a golden board to others th
