Quality Control at Output

The reliability of a manufactured product usually differs from its design reliability due to various quality variations such as nonconforming components and assembly errors. These variations lead to a relatively high early failure rate. Quality control at output mainly deals with quality inspections and screening tests of components and final products so as to uncover and reduce defective items before they are released for sale. The inspected product can be classified into several grades based on the quality characteristics, and the partition between two adjacent grades can be optimized. Similarly, the screening tests (including burn-in and environmental stress screening) can be optimized to achieve an appropriate tradeoff between the test costs and field losses.
