Reliability Monitoring during Mass Production

[As of April, 2011]

Products passing DAT undergo an initial quality assurance inspection before shipment. In addition, periodic reliability monitoring is performed to verify the reliability levels of shipped products. In the initial quality assurance inspection, product initial electrical characteristics and visual appearance are checked. The objectives are to verify the product quality of each product lot and to assure the quality of shipped products.

Periodic reliability verification, i.e., reliability monitoring, involves lifetime and environment tests performed on groups of products classified by process and package family. The reliability level is continuously monitored, failures are analyzed and results are fed back to the manufacturing process. In addition, data is accumulated allowing reliability to be further improved.
