- a) Some believe that AOI does not offer any benefits to their process. They either want, or need, to invest in test and other inspection tools. They feel it is possible to make the process perfect by buying better process equipment and controlling the process variables.
- b) If AOI worked it would be great. They tried it years ago, but it was useless. Nothing has changed, it is more trouble than it is worth. A manual inspection process is all we need.
- c) The current grey-scale machines are ok and can make some contribution to my test strategy, but theyare not easy to use or repeat-able enough. False calls are a problem.
- d) The colour-highlight system out-performs grey scale, but is costly to implement.
- e) AOI is excellent, it would be impossible to effectively run production without this technology.
