Phases of Evaluation and Qualification in Electronic Components

Posted by Manuel Padial Pérez

During the Evaluation phase, components/technologies can be expensively characterized and margins determined. If the evaluation is successful we can then proceed with Qualification, on components produced strictly as defined in the final PID (Process Identification Document) and from a given lot (actually, the first production lot). Once qualified, the component is listed in the QPL (Qualified Part List).
