One important thing to look at, when buying an AOI is the False Calls Rate, along with tact time of machine to inspect the PCB. Obviously, many machines can do the the work....but it's also true that each machine differ from the way it do the work. S

As I was explaining in my thread, the things that you have to look for when buying an AOI is the false calls rate (which you described perfectly) vis a vis the money and time you want to spend. We bought our machine after that we evaluated some. As y
