The customer is the judge of our quality

By embracing the principles and concepts of a “Total Quality Management” culture, Amkor’s quality awareness is inherent in all aspects of business through new product development, manufacturing, administration, sales and customer service. This extends beyond Amkor to include our 1st and 2nd tier suppliers where our “Supplier Partnership Program” is designed to ensure the availability of quality and cost-effective materials and parts. Amkor has been ranked as #1 in supplier quality by many of our customers and is the industry leader in reliability modeling, testing and standardization.
