QUALITY SYSTEMS

Analog Devices uses a zero defect approach to deliver the highest quality solutions to our customers. We engage with our customers early throughout the development process and employ a disciplined approach for building in quality and reliability from product conception through release. Utilizing our globally managed, regionally deployed Quality Management Systems, teams and advanced analysis labs, ADI can ensure the highest level of responsiveness to customer quality needs that meet or exceed internationally recognized standards.

NEW PRODUCT DEVELOPMENT

ADI follows a disciplined product development flow, gated for thorough review at key milestones. Fundamental to this process is an on-going evaluation of risk and activities to mitigate that risk. We employ a number of risk management tools, including FMEAs, multi-disciplined reviews, and experience sharing.

Within the development flow is the ability to adapt to the needs of the application and the customer. A formal documentation review and response system tracks customer- and product-specific requirements for the products ADI develops. Our years of product design experience, close relationships with our customers, and participation on many key industry committees give us the insight needed to create system solutions for a wide range of applications.

Process Development

When needed, advanced processes, such as for fab and assembly, are developed and qualified in a closely-leading track that feeds into the product development flow. ADI internal fabs operate under one quality system, applying the requirements of the most stringent markets they serve to all products.  This approach avoids the possibility of misprocessing while providing the highest level of quality and service to all customers.

Quality by Design

In addition to aggressive performance and value targets, design teams in ADI prioritize Design for Manufacturing and Design for Reliability, from product conception through release.  Under the guidance of Manufacturing, Quality and Reliability teams and systems, each product is developed to make a smooth transition to volume production while also meeting the customer’s requirements for dependability. Cutting-edge Design for Test techniques ensure that shipped product will meet its performance requirements and will be defect-free.  Use of design best practices and the latest design rules are systematically deployed to all ADI Design Centers through centralized support organizations and tools. 

Validation

Once prototypes of a new design are produced, validation begins, employing teams of engineers in test, characterization, design validation, and systems engineering.  The product is evaluated for reliable performance over the application’s range of electrical and environmental conditions.  Qualification stresses, such as burn-in, are also performed to confirm that the product will meet its requirements over its expected lifetime.  Trial production runs verify that the manufacturing flow is meeting the goals for yield and throughput.

Manufacturing Strategy

ADI’s manufacturing operations are optimized to be responsive to rapidly changing customer demand without compromising the highest quality and reliability standards in the industry. ADI enables fast responsiveness by utilizing a flexible supply chain. We employ a mix of internal facilities and external subcontractors. This results in short lead times supporting improved time-to-market for our customers.

Internal Manufacturing

Our internal manufacturing facilities provide proprietary IC technologies. These proprietary processes set the standard in innovation. These IC technologies have few if any second sources; which heightens our focus on quality and reliability over time and temperature, from the first unit to the billionth unit.

External Manufacturing

For external suppliers, we have decades of success utilizing carefully chosen partnerships. These partners are critical components of ADI’s manufacturing strategy and allow ADI access to key process technologies which align with our New Product and Package Development roadmaps. Our suppliers are managed by regionally deployed Logistics and Engineering teams, and the suppliers are expected to compete in fast ramping, cost sensitive vertical markets while meeting strict quality standards. We deploy a rigorous supplier assessment, monitoring, and improvement program to ensure seamless integration, consistent performance and to drive ongoing capability improvements aligned with our commitment to customer’s Zero Defect expectations.

Quality and Reliability

ADI’s products are industry leading not only for the technological capabilities, but also for quality and reliability.  We utilize a multi-faceted approach to ensure strict quality and reliability goals are met or surpassed.  First, product reliability is a cornerstone of our overall quality performance.  We perform extensive reliability testing on new products, processes, and packages during their development and continuously monitor their reliability on an on-going basis.  This results in an industry-leading FIT (Failure in Time) rate.  Second, we use cutting-edge techniques to detect outlier or potentially non-conforming material identified at any stage of the manufacturing process, and employ cross-functional teams who quickly respond to address this material.  Finally, we have developed a zero defect culture at ADI, which has been demonstrated with our success in the most quality sensitive markets, such as automotive, defense/aero and ATE.  We maintain a Continuous Improvement environment that includes process monitoring, failure analysis, and customer feedback which serve as inputs into a Total Quality Management system focused on defect prevention toward attaining zero defects.

Post Sales Support

Customer Quality Support

Customer Quality Teams are the primary interface to customers ensuring high levels of responsiveness to customer quality needs and serving as customer advocates within the organization.  These teams are the cornerstone of our customer focused global Quality organization.  ADI has deployed Customer Quality Teams in each of the major regions across the globe. Regional Teams include: Americas, Europe, Japan, China& Asia-Pacific. These organizations supplement in-region Sales and Applications Teams and have responsibility to provide full product quality life cycle support.

To ensure the highest level of customer satisfaction, ADI utilizes regionally deployed teams for Failure Analysis, Applications Support, and Customer Quality Interface to provide expedited response on customer issues and queries. At ADI, hearing the voice of the customer is not only important during the product development and production phase but also during the post-sales period.

Certifications Timeline

ADI has always been at the forefront of building world class quality, environmental, health & safety management systems around the most highly recognized and respected international standards. Early deployment, registration and continuous improvement of these systems has served as the foundation of our Total Quality Management philosophy and enabled ADI to become a recognized leader within the semiconductor industry.

Issue Resolution

ADI utilizes the 8D (8 Discipline) method for issue resolution , with over one hundred certified 6 sigma green belt and black belts trained and ready around the globe.  ADI’s comprehensive approach to issue resolution is supported by strong information systems to ensure quick and effective containment.  Failure verification and analysis is performed at advanced labs in Asia, Europe, and North America.  Our quality and engineering teams work with customers to identify and permanently eliminate root cause of failures.  Using the 8D process, ADI ensures corrective actions and preventive actions are identified, verified, and fully deployed.   Achieving “Zero Defects” for shipped products is the goal for ADI.

Returning Product for Failure Analysis

A request for Failure Analysis must be made through the same channels that you purchased the parts from (your ADI authorized distributors and sales offices). They will assist you in filling out the necessary 'Customer Alerts & Returns Environment' (CARE) form and expediting the issue resolution process. Further details can be found in Customer Collaboration with Failure Analysis Requests.

Authorized Sales Channels

ADI provides full support on our products purchased through ADI-authorized distributors and sales offices, including quality, reliability, failure analysis, and applications support.

ADI cannot determine the origin or legitimacy of products procured through brokers or other non-authorized sources. We cannot provide warranty coverage or any quality, reliability, failure analysis, applications, or other support on such products. ADI will neither accept returns nor provide credit on products that have been purchased from brokers or other non-authorized sources. Recent articles in semiconductor industry publications have reported the availability of used, damaged, and counterfeit products on the broker market. The leading reason that customers experience IC failures is because the products have been purchased from non-authorized sources. Non-authorized sources often sell products which may have been improperly handled/stored or may be counterfeits. For more details, please see the SIA Anti-Counterfeiting Task Force Whitepaper. Therefore, to ensure you are receiving unused, authentic ADI product, and to take full advantage of the industry-leading reliability levels of ADI’s products, please ensure all purchases are made through the ADI authorized distributors and sales offices.
