In the existing semiconductor industry, chip tape is widely used as a common chip packaging method; however, during the packaging process, chips and chip tapes may have appearance defects such as chipping and scratches caused by foreign matter; therefore, it is necessary to Chip taping for visual inspection.

Traditional detection methods are mostly artificial naked eye detection or large-volume multi-station detection methods; on the one hand, such detection methods have low detection efficiency; on the other hand, labor costs and device layout costs are high and the site layout requirements are cumbersome. In addition, the existing inspection equipment lacks reasonable light source arrangement, and it is difficult to cover both the front and back sides of the chip tape where appearance defects may exist; thus, the detection rate of appearance defects of the existing inspection methods is poor; and, Since the chip tape widths of different manufacturers vary, it is difficult for traditional detection methods to be optimally used to detect chip tapes of different widths.

Then the multi-station inspection system takes visual images of the front side of the chip tape and transmits the image to the algorithm for processing;

Step 3: One-time collection

For positive detection results, when the detection result indicates a defective product, manual judgment processing is performed and the power is restored. When the detection result does not indicate a defective product, the power is restored directly without manual processing; then the power drives the chip braid to move along the conveyor flow channel, and the positive detection The finished chip tape is wound up and fixedly wound tightly on the material tray on the other side of the testing equipment;
