[0002] At present, in the process of semiconductor packaging, there is a step near the end of the process that requires printing specific labels or QR codes and other data on the fully packaged chip. Since the chip size is generally small, the chip may be misplaced in the tray for various reasons, resulting in the offset of the printing position. In some cases, the quality of laser printing is not up to standard, the color is too light, etc. Therefore, there will be a manual confirmation process after the printing is completed, which can not only select the defective materials with incorrect printing, but also need to check the front and back of the tray after printing.

[0003] In the existing process, it is necessary to observe bad printing materials with the naked eye, which leads to low production efficiency and consumes a lot of operator time and energy. This process is very time-consuming and human observation is prone to misjudgment, which directly leads to reduced production efficiency. In order to overcome the existing problem of low efficiency caused by using manpower to judge bad materials, the equipment developed by this technology can detect defective products through observation with visual equipment.
