Quality Management

Quality management

• Continuously establish new membrane material validation indicators, adjust for optimization, and assist in breakthrough process technology.
• Investigate and simulate end customers' and consumers' usage patterns to further enhance the capabilities of new products.
• Collect historical OK/NG data for machine learning analysis and establish key process influencing factors.
• Implement equipment warning monitoring, automate data collection through scanning, and build an IoT platform.
• Upgrade the hardware and software of automated optical inspection systems to promptly detect production abnormalities and reduce product failure rates and production costs.
• Utilize and leverage quality tools such as failure mode and effects analysis, continuous improvement projects, and quality improvement methodologies.

Supplier Quality management

• Conduct quarterly business review (QBR) evaluations every six months and arrange on-site audits for suppliers who have quality issues during the current year. Confirm and track the effectiveness of supplier improvements to prevent further quality problems.
• In 2022, abnormal properties were identified in the protective film, including excessive anti-static impedance and color deviation. A defect validation risk assessment was conducted to ensure it did not affect product quality. Abnormal raw materials were disposed of, totaling 330 kilometers.

Product return

• The return rate of 0.148% has met the target (with a return rate target set at 0.15%).
