“Commitment to Excellence at Quality & Reliability!”

To achieve this vision, AOS continuously strive for the excellence in design, manufacturing, reliability

and proactively response to the customer’s feedback.

AOS ensures that all the product quality and reliability exceed the customer’s expectation by

constantly assessing any potential risk, identifying cause of the suspected failures, driving corrective

actions and developing prevention plan within the committed time through the continuously

improvement.

This AOS product reliability report summarizes AOS Product Reliability result. The published product

reliability data combines the results from new product Qualification Test Plan and routine Reliability

Program activities. Accelerated environmental tests are performed on a specific sample size, and

then followed by electrical test at end point. The released product will be categorized by the process

family and be monitored on a quarterly basis for continuously improving the product quality. Table 1

lists the generic reliability qualification requirements and conditions:
