Scope

Improvements in manufacturing .technology and methodology have resulted in corresponding quality improvements for electronic components. As a result, the traditional measure for reporting average quality levels in percent nonconforming needs to be replaced with a quantity more in line with the quality levels of today. That measure is parts-per-million or ppm. It is simply clearer to report estimated average component quality as 1 O ppm, rather than the more cumbersome 0.001 %. The ppm terminology applies to estimating the average outgoing quality (AOQ) level of a component, from lot acceptance results.
