Quality Lasts Life

author: Jerry Wu

    Quality and Product Reliability Engineering is the vital engineering in Wuxi China Resources Micro-assembly Technology CO., Ltd (ANST). Based on the company Quality Policy of “Continuous Improvement, Customer Satisfaction, and Towards to Zero Defect”, ANST is introducing in the advanced Quality Management Concept and continuously optimizing the in-line quality management and reliability engineering system. Up to now, ANST has already been certified to the industry & national quality standards with ISO 9001:2000 (quality management system certification), GB/T 24001-2004/ISO 14001:2004 (environment management system certification) and GB/T 28001-2001 (employment health and safety management system certification). We are striving to achieve the world class quality on both product and service and to be a solid platform of Integrated Circuit Assembly & Test manufacturing & service for domestic customers and overseas customers as well.

    The Document Control Center (DCC) in ANST controls the company quality manuals, process procedures and working/inspection instructions effectively according to the ISO 9001 standards. Besides the unified numbering system set up for the records which are related to the product quality control, DCC also periodically evaluates, verifies and updates all controlled documentations to make sure the effective guidance to working processes.

    The quality of incoming materials directly affects our quality of process controls and finished goods. To ensure the in-line quality control, we have introduced in overseas experts and implemented the advanced management methods, which include material suppler verification & qualification procedure set up to strictly control the new supplier approval and qualification, supplier grading system set up to grade suppliers periodically, and audit system set up to perform supplier audit on quality management system and on-site process control periodically.

    To ensure the quality control of in-line products, ANST has already implemented the SPC system on each relative process for assembly & test. The control target of LRR/PPM has been set up. Quality Control Inspectors on the production lines are strictly controlling the process quality according to the respective quality control standards. Failure Mode Evaluation & Analysis (FMEA), Positrol Plan and Out of Control Action Plan (OCAP) also have been successfully introduced in with the data collection and experience built up. Based on the statistic data analysis on the respective in-line process quality control and problem finding with the advanced statistic data analysis tools, we are able to bring forward corrective actions according to customer requirement.

    ANST committed itself to improve continuously, satisfy customer’s requirement and treat any customer complains seriously. To prevent the same problem of each customer complain appearing again, QE engineer will coordinate and organize a problem solving group, implement containment actions, analysis the problem, find the root cause with process simulation and DOE, and then cerate the corrective actions and preventive actions as well. In the end, QE engineer will provide an 8D report to the respective customer within the defined response time. QE engineer will also review the data of customer complains regularly and perform statistic analysis to find the failure mode and solve the quality problem pertinently.

    Reliability Test and Failure Analysis capability are the key factors for providing the good quality product and service to our customers. To ensure the product quality and improve process techniques, ANST has invited experienced Reliability & FA expert join-in and invested an advanced Reliability & FA Laboratory equipped with imported and advanced equipment and instrument, which includes 100% Convection Reflow Oven System, Decaper, TH, TC, Autoclave, CSAM, Cross-Section, and etc. We not only monitor the reliability of in-line products, but also build up the reliability test items on both short term and long term and regular reliability monitoring for different package type and BOM. All of these are to ensure the better quality from new product release to high volume manufacturing.

    We believe that quality is the life and hope of our company. All ANST employees are improving their quality mindset through continuous training. With fully understood the importance of the real meaning of “Do it right the first time all the time (No Rework)”, each of ANST employee is building up the quality concept and responsibility on both product and service. Leading by the advanced quality culture, ANST will aspire and realize its vision of “To be the top ten semiconductor assembly and test company in the world” and become the Customer’s first choice while considering the semiconductor assembly and test service.
