As an SMT assembly AOI user my group has had the same experience with component variability and templates. The equipment we use has the option to teach alternate components (machine will compare current image to a list of known good models and require only one match to pass) which provides some relief to the constant tweaking. New variations still cause problems but are captured in a central library for use later. Personally I always thought the ability to use OCR in templates would be a valuable tool in this situation, but I have never used a system with this capability.

Yes, we bought an AOI machine and have it up and running. The problem is that with each reel changed on the p'n'p machines, the writing on the components changes and the templates have to be readjusted. Is it natural? The component engineer cannot impose font and alignment requirements so we're stuck with tweaking the programs intensively. Is this a problem that everybody has? Is this machine dependent and we chose the wrong one? Are we not knowledgeable enough to do the right programming? Any tricks to get better results?
