Another issue to look at is the efforts that it takes to become familiar with the machine. Where I work we are also looking into AOI machines, and one of our requirements (based on how simple the vendors say their machines are) is that after no more than 40 hours of training and practicing, the average SMT production engineer must be able to make a good inspection program in a more or less efficient way. What I have seen so far is that programming an AIO system is much too complicated to meet this requirement, and that it actually takes a huge amount of expertise and training to obtain the necessary skill-level.
I would love to hear some comments on this !
