Technical details and manufacturing context for Automated Optical Inspection (AOI) System

Definition

An integrated production system that uses high-resolution cameras, lighting modules, and image processing algorithms to automatically inspect electronic components and printed circuit boards for defects during manufacturing. The system typically includes material handling modules, multiple inspection stations, and data management interfaces. It performs non-contact inspection of solder joints, component placement, markings, and physical defects at production line speeds. The system is constructed with an aluminum frame, optical glass, copper wiring, steel rails, and PCB controllers. Key parameters include a field of view of 10–50 mm, camera resolution of 5–20 megapixels, throughput of 30–120 units per hour, and inspection accuracy of ±0.02–±0.05 mm. It supports minimum component sizes of 0.2–0.5 mm, operates in temperatures of 10–35 °C and humidity of 20–80% RH, and requires a 220 V AC ±10% power supply with consumption of 1.5–3.0 kW. The system weighs 800–1500 kg and has dimensions ranging from 1200×1000×1600 mm to 2000×1500×1800 mm. It has an IP rating of IP40–IP54 per IEC 60529. Lighting types include LED, RGB, UV, and IR. These values are reference ranges; verify model-specific specifications with the manufacturer.

Working Principle

High-resolution cameras capture images of components under controlled lighting, which are analyzed by computer vision algorithms to detect defects against programmed acceptance criteria. The system uses multiple lighting modes (LED, RGB, UV, IR) to highlight different features. Images are processed in real-time, comparing against reference patterns and tolerances. Defects such as missing components, misalignment, solder bridges, or incorrect markings are flagged for review or rejection. The system operates at production line speeds, with throughput up to 120 units per hour. Calibration and programming are required for each product type. Environmental conditions (temperature, humidity) must be maintained within specified ranges to ensure accurate inspection.

Frequently Asked Questions

What defects can an AOI system detect?

An AOI system detects solder joint defects, component placement errors, missing or wrong components, incorrect markings, and physical defects such as scratches or cracks. It uses image processing to compare captured images against programmed acceptance criteria.

What is the typical throughput of an AOI system?

The throughput ranges from 30 to 120 units per hour, depending on the model, inspection complexity, and conveyor speed. Verify the specific throughput for your application with the manufacturer.

What environmental conditions are required for operation?

The system operates in temperatures of 10–35 °C and humidity of 20–80% RH (non-condensing). High humidity can fog optics, and temperatures outside this range may affect camera calibration.

How should I verify the system's specifications?

Always confirm model-specific values for field of view, resolution, accuracy, and other parameters with the legal manufacturer or supplier. The listed ranges are reference values for directory purposes only.
