Technique for transfer of analog prototypes (DV´s) to production

The author discusses several of the statistical analysis techniques available to both development and manufacturing engineering and how these techniques can be applied to assist in product characterization and introduction. It is pointed out that statistical analysis techniques, such as regression analysis and statistical capability studies, are useful in the characterization of a new design and its subsequent introduction into full-scale production. The benefits from these analyses include identification of potential yield-impacting parameters before significant manufacturing resources are committed to full-scale production; an understanding of how and where to attack yield issues, i.e., through parameter centering or variability reduction; possible reductions in test development times and production test costs through simplification of test lists, verified by regression and/or correlation analysis. By applying the techniques discussed, the time required to bring a new design into full production with a clear understanding of its capabilities and the interdependencies among its electrical parameters can be reduced
