Manufacturing and engineering companies in need of a solution to enhance their product reliability
About PAT-Man
Facing strict quality demands from the automotive industry, semiconductor companies are increasingly applying Part Average Testing (PAT) to enhance reliability. PAT identifies and removes "outlier" parts that pass standard tests but exhibit abnormal characteristics, reducing long-term quality and reliability issues. By statistically analyzing multiple devices and adjusting pass/fail limits, PAT proactively identifies these problematic parts for exclusion, ensuring only the most reliable components reach production shipments. Part Average Testing ( PAT ) as detailed in the Automotive Electronics Council AEC-Q001-Rev C specifications only covers DPM techniques for normal (Gaussian) distributions. However, many distributions do not fall into the Gaussian category and require adapted PAT outlier detection methods to avoid excessive yield loss or incorrect outlier detection. PAT-Man is a comprehensive solution for Part Average Testing (PAT).
