AOI Engineer

AOI Engineer

The AOI Engineer is responsible for in-process detection engineering, SPI (Solder Paste Inspection), AOI (Automated Optical Inspection), and Ball Grid Array X-Ray, for both new product introduction (NPI) and sustaining engineering activities. This role plans and creates inspection programs, defines detection strategies, troubleshoots SMT process issues to root cause, and drives continuous improvement of inspection capability and quality across the production line.

The AOI Engineer works cross-functionally with engineering, quality, production, and customers to ensure inspection processes support product quality and manufacturing efficiency.

Inspection Programming & Process Engineering

• Plan, create, and maintain SPI/AOI/X-Ray programs and ensure process documentation is completed and updated in time for production

• Develop and provide SPI/AOI/X-Ray programs and technical support for new product introduction (NPI)

• Monitor SPI/AOI/X-Ray inspection and detection windows and modify as necessary to increase machine capability, reduce false calls, and improve quality

• Continuously review and improve the strategy and technology used in SPI/AOI inspection processes

Troubleshooting & Quality

• Troubleshoot SMT process issues (SPI/AOI/X-Ray) to root cause and implement corrective actions in response to internal and external quality feedback

• Perform comprehensive line quality troubleshooting using sound engineering principles

• Analyze defect trends, generate reports, and recommend corrective actions to improve product quality

• Assist in major machine breakdown troubleshooting and coordinate repairs or maintenance as needed

• Work with Quality (QMM) on in-process and line audits

Systems, Equipment & Continuous Improvement

• Ensure area computers and network systems are maintained in operational condition, with inspection programs regularly updated and backed up

• Maintain and upgrade machine capability through engineering benchmarking projects

• Perform routine maintenance, updates, and calibration oversight on AOI and X-Ray equipment to ensure consistent performance

• Recommend and implement process improvements to enhance inspection accuracy, cycle time, and overall production efficiency

• Stay current on industry trends and AOI/X-Ray technology advancements to enhance inspection techniques

Collaboration & Training

• Participate in new product development discussions and contribute ideas in the areas of PCB assembly automation and process technology

• Work with the engineering systems team on new release processes for SPI/AOI/X-Ray-related programs

• Provide training in machine maintenance, operation, and detection processes to technical support personnel

• Communicate effectively with cross-functional teams, management, and customers

Qualifications:

• Bachelor's degree in Mechanical, Electrical, or Computer Engineering (or equivalent) (preferred)

• Minimum 3 years of related working experience in SMT/electronics manufacturing

• Experienced with SMT machinery and processes (screen printing, pick and place, reflow)

• Able to generate SPI/AOI programs and read/interpret board schematics and engineering drawings

• Expertise in engineering principles sufficient to perform comprehensive line quality troubleshooting and root cause analysis

• Working knowledge of IPC-A-610 acceptance criteria preferred

Physical Requirements:

· Ability to sit, stand, walk, reach with hands and arms, and use hands to operate standard office and inspection equipment.

· Occasionally required to stoop, kneel, crouch, or crawl.

· Must be able to lift and/or move up to 25 pounds occasionally.

· Must be able to work in environments that include manufacturing floors, clean rooms, and test labs, with occasional exposure to machinery or moving parts.

· Reasonable accommodations may be made to enable individuals with disabilities to perform the essential functions of the role.
