Technical details and manufacturing context for Illumination System

Definition
The Illumination System is a critical component within an Automated Solder Paste Inspection (SPI) System that generates precisely controlled lighting conditions to illuminate the printed circuit board (PCB) surface. It enables the system's cameras to capture clear, high-resolution images with optimal contrast between the solder paste deposits and the PCB substrate, which is essential for accurate measurement of paste volume, height, area, and alignment. The system typically employs multiple LED light sources arranged at specific angles (such as coaxial, ring, or dome lighting) to create controlled illumination patterns. Different lighting modes (bright field, dark field, or multi-angle) are used to highlight various features of the solder paste deposits. The intensity, color temperature, and angle of illumination are precisely controlled to minimize reflections, shadows, and glare while maximizing contrast for the inspection algorithms. Key parameters include a wavelength range of 450–650 nm, color temperature of 5000–7000 K, illuminance adjustable from 5000 to 20000 lux, and light uniformity of at least 90%. Power consumption ranges from 10 to 50 W, with a standard 24 V DC input (±10%). The system operates in temperatures from 0 to 40 °C and can be stored from -20 to 60 °C, with relative humidity of 20–85% (non-condensing). Ingress protection is rated IP54–IP65 per IEC 60529. The housing is made of aluminum, and the unit weighs between 0.5 and 2.0 kg, with dimensions customizable from 100×100×50 mm to 200×200×80 mm. Materials include high-brightness LEDs, optical diffusers, aluminum heat sinks, and polycarbonate lenses. This directory entry provides reference ranges; actual model-specific values and standards must be verified with the legal manufacturer or supplier.
Working Principle
The system uses multiple LED light sources arranged in configurations such as coaxial, ring, or dome lighting to create controlled illumination patterns. Bright field, dark field, or multi-angle lighting modes highlight different features of solder paste deposits. Intensity, color temperature, and angle are precisely controlled to minimize reflections, shadows, and glare while maximizing contrast for inspection algorithms. The LEDs provide stable color temperature and long life, with wavelength in the visible spectrum (450–650 nm) for optimal solder paste contrast.
