For end-of-line testing of modern multifunction units, MCD Elektronik has developed a flexible, modular test bench specifically designed for three different product variants. The goal is to ensure consistently reliable quality control in mass production while maintaining a high degree of flexibility in handling different variants.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\t

The test bench enables comprehensive testing of functional, electrical, and mechanical properties under defined and reproducible test conditions. This includes, among other things, programming and verifying button functions, as well as validating wireless, Bluetooth, and wired interfaces.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\t

Thanks to its modular design, the testing process can be quickly adapted to different device configurations without compromising production speed. The system is complemented by the integrated MCD AudioAnalyzer, which precisely evaluates voice and audio signals, thereby ensuring consistently high communication quality.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

To ensure measurement and test reliability, the test bench is validated as part of a measurement system analysis (MSA) in accordance with V1 and V3. In the V1 analysis, measurement deviation and system stability are determined based on 50 repeat measurements of an identical test specimen without mechanical movement. From this, meaningful metrics for assessing system capability can be derived.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
