In testing placement accuracy, for example, the actual fine pitch QFP components and various types of leaded devices used in product assembly can now be applied. The pick and place machine puts the components on the CeTaQ test fixture, a highly accurate glass plate marked with local reference points and fiducials. The components are analyzed against specification data from component data sheets.
Measurements and statistical data are collected for calculating Cp and Cpk indices on side overhang, toe overhang, and lead pitch for example. These results can be used to feedback quality of incoming component material to component suppliers. Software operates the measurement equipment and provides statistical specification-based results on machine quality performance. Comprehensive certification reports validate performance, which allows users to improve product quality and optimize performance for increased manufacturing profitability.
