Q1: What are the advantages of RGB illumination for AOI inspection?
A: RGB illumination enhances contrast on different materials and surfaces, making it easier to detect solder defects, component misalignment, scratches, and surface contamination.

Q2: Can each color channel be controlled independently?
A: Yes. Red, green, blue, and optional white LEDs can be controlled separately, allowing users to optimize lighting conditions for specific inspection tasks.

Q3: What applications are these ring lights designed for?
A: They are ideal for PCB solder inspection, SMT assembly verification, semiconductor packaging, connector inspection, and general surface defect detection.

Q4: Are illumination angles customizable?
A: Yes. LED emission angles can be customized to improve visibility on reflective, multilayer, or uneven surfaces.

Q5: What power supply is required?
A: All models operate on a standard 24V DC industrial power supply, simplifying integration into existing machine vision systems.

Q6: Can these lights be used with line scan or area scan cameras?
A: They are primarily designed for area scan AOI systems but can also be integrated with specialized inspection setups depending on application requirements.

Q7: Which defects can be detected in PCB inspection?
A: Missing components, wrong parts, tilted components, insufficient solder, excessive solder, and open solder joints can all be effectively highlighted using multi-color illumination.
