The client had requirements to carry out final product testing that included mechanical operations, visual inspection and performance tests. There are the standard production needs of containing cost, throughput, yield, ease of maintenance and reliability. It was felt that a vision system would address the inspection needs and produce repeatable high quality tests but what about the total test requirements?

QM Systems addressed the problem as a whole considering all aspects including fixture requirements, hardware instrumentation, interfacing and software to provide a fully integrated functional test solution. Although monochrome display testing is common the phone has a large high resolution colour display.

In order to address the complete requirement QM had to develop the solution in a flexible software environment with comprehensive tools. For the client, ease of use and future reconfiguration were fundamental requirements .The test executive selected was NI TestStand. The comprehensive feature set and robust environment make this package ideal for the development of production test solutions. TestStand can be implemented at different levels and so affords accessibility to the production engineer but also depth and flexible tools for the software experts. NI vision solutions were then an obvious choice for developing the vision testing of the display performance and visual feature inspection. The range of tests and controls implemented are outlined in graphic below:
