- Position: AOI Technician

- Department: Production / Quality

- Industry: Electronics Manufacturing / EMS

- Experience: 2 - 5 Years

- Qualification: ITI / Diploma / Engineering in Electronics or Electrical

Key Responsibilities

- AOI Machine Operation: Operate Automated Optical Inspection (AOI) machines to inspect PCB assemblies for component placement and soldering defects.

- PCB Inspection: Identify missing components, misaligned components, wrong components, polarity issues, solder bridges, insufficient solder, and other assembly defects.

- Program Selection: Select the correct AOI inspection program based on the PCB model and production requirements.

- Defect Verification: Review AOI images and alerts to distinguish actual defects from false calls.

- Quality Inspection: Ensure PCB assemblies meet established quality standards before proceeding to the next production stage.

- Defect Classification: Identify, classify, and record defects according to approved inspection criteria.

- Defect Segregation: Segregate defective or suspected PCBs and prevent nonconforming products from moving to the next stage.

- First-Piece Inspection: Perform first-piece inspection and verify inspection results after product changeovers or program changes.

- Production Monitoring: Complete inspections within the required cycle time while maintaining inspection accuracy and production targets.

- Program Changeover: Load the appropriate AOI program during product changeovers and verify the inspection setup before production resumes.

- Rework Coordination: Communicate detected defects to the SMT production or rework team and verify corrective actions as required.

- Documentation:



Maintain inspection reports, defect logs, rejection records, and production data accurately.

- Traceability: Ensure proper barcode scanning, PCB identification, and traceability of inspected products.

- Machine Maintenance: Perform routine machine cleaning and basic checks and report equipment issues to the maintenance team.

- ESD and Safety: Follow ESD precautions, PPE requirements, and workplace safety procedures while handling PCBs.

- 5S: Maintain cleanliness and organization at the inspection workstation.

- Abnormality Reporting: Escalate recurring defects, machine errors, and unusual inspection results to the Production Supervisor or Quality team.

- Continuous Improvement: Support defect reduction, root-cause analysis, and process improvement activities by sharing inspection data.

- Training: Stay updated on AOI machine operation, inspection standards, defect identification, and quality procedures.

Required Skills

- 25 years of hands-on experience operating AOI machines in SMT/PCBA manufacturing.

- Positive knowledge of SMT processes and PCB assembly.

- Ability to identify component placement and soldering defects.

- Experience reviewing AOI images and verifying false calls.

- Basic knowledge of inspection programs, defect classification, and quality documentation.

- Understanding of ESD precautions, 5S, and production safety.

- Good attention to detail and problem-solving skills.

Preferred Experience

- Experience with post-reflow AOI inspection.

- Exposure to SPI (Solder Paste Inspection) and other SMT inspection processes.

- Experience in an Electronics Manufacturing Services (EMS) environment.
