SPC

Definition

Statistical Process Control (SPC) is a methodology used to monitor and control a manufacturing process through the use of statistical techniques. By analyzing data collected from the process, SPC helps in identifying variations that may indicate problems, allowing for timely interventions to ensure quality and efficiency in production. This approach is particularly important in industries like semiconductor manufacturing, where precision and consistency are critical for product performance.
