Visual inspection refers to the process of converting the target being captured into an image signal through machine vision products (i.e., image acquisition devices), which is then transmitted to a dedicated image processing system. Based on pixel distribution, brightness, color, and other information, the image signal is transformed into a digital signal. It holds immense value in detecting defects and preventing defective products from being delivered to consumers.

The professional research team at Allmerit has developed software with independent intellectual property rights, which also possesses the capability for upgrades and modifications. The software can be customized to utilize advanced artificial intelligence (AI) deep learning algorithms, resulting in high accuracy, significantly reduced false detections, and significantly improved production efficiency.

Kuangqiyingshi®-100 (QFN)

Offline QFN Lead Frame Inspection

Primarily suited for inspection of etched lead frames of QFN.

The main inspection items include detecting stains, discoloration, sand holes, plating area deviation, silver deficiency, silver leakage, deformation, over-etching, connected pins, and other defects in the electroplated areas such as frames, pins, and base conductors that are visible under illumination.

Product specifications for inspection: Copper material, length ranging from 160-300mm, width ranging from 30-100mm; thickness between 0.102mm and 0.508mm inclusive, with a bending depth less than 1.2mm. It supports double-sided inspection.

Appearance resolution: 0.04mm; UPH (Units Per Hour) is 6-8 pieces/minute; missed detection rate is less than 0.02%; over-detection rate is less than 0.15%.

Display of Product Defects

After inspection with Allmerit's visual inspection equipment, the defects in the product will be nowhere to hide, enabling effective screening of defective products. Additionally, the images can reflect any issues with the production equipment, allowing for timely maintenance and adjustments, which will greatly improve product qualification rates.
