Engineering Risks & FAQ - **Caution**: - **Caution**: - **Caution**: ### Q: What types of defects can this AOI system detect? **A**: The system detects common manufacturing defects such as missing components, misaligned parts, solder bridges, and surface imperfections. It also identifies issues with solder joints and PCB traces. The specific defect types are listed as solder, trace, and component defects. ### Q: What is the maximum PCB size that can be inspected? **A**: The maximum PCB size supported is 510×460 mm. Boards larger than this may not be accommodated. Verify the exact dimensions with the manufacturer for your specific application. ### Q: What are the environmental requirements for operation? **A**: The system operates in temperatures from 10 to 40 °C and relative humidity from 20% to 80% RH (non-condensing). High humidity may cause fogging, and operating outside these ranges may affect accuracy. Ensure the installation environment meets these conditions. ### Q: How accurate is the defect location? **A**: The detection accuracy is ±0.05 mm, meaning the system can pinpoint defect locations with high precision. However, actual performance may vary based on the inspection resolution, lighting, and PCB complexity. Confirm with the manufacturer for your specific setup. ## 6.
