• Performed machine setup, feeder loading, component verification, and model changeover. • Operated SMT production line including solder paste printer, pick-and-place machines, and reflow oven. • Read and followed BOM, work instructions, and production schedules. • Ensured correct component placement, polarity, and orientation. • Monitored machine operation and responded to alarms, errors, and stoppages. • Identified and segregated defective boards (NG) and reported quality issues. • Performed troubleshooting, nozzle cleaning, and feeder maintenance. • Maintained production records, downtime logs, and check sheets. • Followed ESD, safety procedures, IPC standards, and 5S practices. • Coordinated with technicians, quality, and supervisors to meet production targets.

• Assigned to multiple departments (Automotive, FE Module, IFV), ensuring KPI targets were achieved. • Investigated optical module failures including transceiver misalignment, signal loss, and connector contamination, identifying root causes to improve product reliability. • Conducted detailed optical inspections and testing using power meters, and high-resolution microscopes to pinpoint defects and assess performance degradation. • Performed root cause analysis and problem-solving through structured methods (5-Why, Fishbone, 8D), driving effective corrective and preventive actions. • Produced comprehensive FA reports with actionable insights, collaborating with R&D, quality, and process teams to implement solutions and monitor recurring issues. • Assisted in customer complaint resolution and RMA investigations, translating technical findings into practical recommendations to reduce future failures.
