• Support AOI setup and qualification for new PQFN package introductions.
• Develop inspection recipes according to product specifications and customer requirements.
• Participate in process characterization and production qualification activities.
• Ensure AOI readiness before mass production.
• Analyze AOI inspection data to identify process trends and yield loss.
• Work with Process Engineers to eliminate recurring assembly defects.
• Drive continuous improvement projects to improve inspection efficiency and first-pass yield.
• Support root cause analysis for quality excursions.
• Investigate AOI-detected defects and verify inspection accuracy.
• Classify true defects versus false calls.
• Maintain defect libraries and golden sample databases.
• Recommend corrective actions to reduce defect occurrence.
• Support AOI machine setup, calibration, verification, and qualification.
• Coordinate machine upgrades, software updates, and hardware improvements.
• Monitor AOI equipment performance and utilization.
• Ensure AOI inspection complies with internal quality standards and customer requirements.
• Support quality audits and customer visits related to AOI processes.
• Maintain inspection documentation, work instructions, and validation records.
• Ensure compliance with ISO, IATF 16949, and applicable manufacturing standards.
• Monitor AOI KPIs such as False Call Rate, Escape Rate, Detection Rate, Yield, and OEE.
• Perform statistical analysis to identify process improvement opportunities.
• Prepare technical reports and present findings to cross-functional teams.
• Lead or participate in Lean, Six Sigma, Kaizen, and cost reduction projects.
• Improve AOI programming standards and inspection methodologies.
