Typical modern production processes, consist mainly of a series of single steps. For example combinations of electronic and mechanical parts are assembled to become a module. The parts are inserted and adjusted, screws or locking devices are used to secure and warning labels are applied.
To receive a flawless end product and at the same time reduce the costs for quality control and on-going maintenance, inspection is required to make sure faults do not arise. AOI (Automatic Optical Inspection) allows an economical test of various processes.
Automatic and manual fabrication steps can therefore be verified using many diverse criteria. There is a demand for a flexible solution; it should provide a test with different requirements and without an elaborate and complicated test program.
