I. Key Testing Parameters for LED Chips

1. Dimensions: LED chip diameter, overall height, pin pitch, package dimensions, etc.;

2. Visual defects: surface scratches, chipped edges, cracks, missing material, excess material, pin deformation, black spots or impurities, package misalignment, etc.;

3. Luminous performance: electrical, optical, and color parameters such as luminous intensity, color temperature, color tolerance, luminous uniformity, forward voltage, reverse leakage current, etc.

II. Complete Visual Inspection Configuration Solution

1. Imaging Lens: A zoom industrial lens compatible with LED chips of various specifications, supporting both dimensional measurement and visual defect detection;

2. Illumination: A ring-shaped vision light that provides uniform illumination, eliminates glare, and clearly highlights subtle surface defects;

3. Imaging Device: A high-definition industrial camera that captures high-resolution images of fine details, ensuring accuracy in measurement and defect identification;

4. Software System: Image inspection system that performs dimensional measurement, visual defect identification, and automatic sorting of good and defective products.

LED chip inspection primarily focuses on the chip’s dimensions (such as diameter and height), visual quality (presence of defects or cracks), and luminous performance (brightness, color temperature, etc.). ZOOM LENS inspection solution can assist in performing dimensional and visual quality inspections.
