PCB/PCBA electronic components (plug-in)

PCB plug-in visual inspection

Traditional PCB component inspection relies on manual visual inspection. However, there are many solder joints and small parts on the PCB.


Manual inspection is labor-intensive, low in efficiency, and easily affected by individuals. The influence of these factors greatly limits the improvement of enterprise production efficiency and product quality.

Testing requirements and procedures

Inspection process is as follows: 

  1. With the product in place, the client device gives a trigger signal. 
  2. Industrial camera completes the image acquisition.
  3. Visual inspection system checks the contents of the inspection:
    • Mixing detection.
    • Component presence or absence detection 
    • Component positive and negative detection
    • Component color detection
    • Component direction detection 
    • Wire color detection, terminal seat color detection, terminal seat direction detection with efficient analysis and processing.
  4. OutputOK/NG result to the client’s designated terminal with the processed result.
