Job Description
The 3D AOI Operator is responsible for ensuring the quality and reliability of printed circuit boards (PCBs) through precise automated optical inspection. This role involves operating advanced inspection equipment to identify manufacturing defects and collaborating with production teams to maintain high standards. The operator plays a key part in the final quality control process before products move to the next assembly stage.
Key responsibilities include:
• Operating the 3D Automated Optical Inspection (AOI) machine to examine PCBs.
• Setting up, optimizing, and running inspection programs tailored for different board designs.
• Inspecting PCBs for critical defects such as missing or misaligned components, solder bridges, insufficient or excess solder, tombstoning, lifted leads, and polarity issues.
• Coordinating directly with SMT, Quality Control (QC), and Process Engineering teams to communicate findings and resolve defect root causes.
• Maintaining accurate daily inspection logs, detailed defect reports, and yield data for process tracking.
• Performing routine daily machine checks, preventive maintenance, and calibration to ensure equipment accuracy.
Skill Requirement
The ideal candidate will possess a solid educational foundation in electronics along with hands-on experience in a PCB manufacturing environment. Success in this role requires a sharp eye for detail, a strong understanding of surface-mount technology processes, and the ability to work collaboratively across departments to drive quality improvements.
Required skills and qualifications are:
• A Diploma, ITI certification, or Engineering degree in Electronics or a relevant field.
• 2 to 3 years of proven experience specifically as a 3D AOI Operator within PCB assembly.
• Hands-on experience with SMT production lines and practical knowledge of AOI programming.
• Strong understanding of SMT processes and the ability to identify various soldering defects.
• Proficiency in reading and interpreting PCB assembly drawings, Bill of Materials (BOMs), and component datasheets.
• Basic computer skills, including the use of inspection software, generating reports, and working with MS Excel for data management.
