Has anyone used their AOI to try to catch components that may be inadvertently placed in a location it shouldn't be? Every once in a while our equipment may drop a part onto a PCB and that part will adhere to pad. So the question has been brought u

It is a very interesting thought. However, teach all positions on the PCB might be challenging if you don't have them in the file. I think it is a smart think for OEMs as they would have all the resources to control their files. For CEM I don't see i
