The high-precision visual inspection system is based on multi-view stereoscopic imaging and laser measurement technology, which can conduct three-dimensional shape reconstruction of the circuit board in all directions. The system acquires complete point cloud data of the board surface through high-speed scanning, and uses intelligent algorithms to accurately identify key features such as the circuit trace, hole diameter, and pad shape, achieving full-process quality monitoring from raw materials to finished products.
The core detection capabilities of the system include: precise measurement of wire width, analysis of positional deviations between through-holes and blind-holes, assessment of coplanarity of surface mount components, and verification of solder mask integrity. For the fine lines in high-density interconnect boards, high-magnification optical imaging combined with sub-pixel processing technology is employed to break through the traditional detection resolution limit and accurately capture potential process defects.
During the soldering process of the circuit board components, the system can detect the consistency of pin heights, the soldering penetration status, and the bridging risks, effectively identifying common manufacturing issues such as void soldering and pillar formation. For the layer alignment accuracy of multi-layer boards, through X-ray and three-dimensional reconstruction technology， non-destructive internal structure quality verification is achieved.
This technical solution has been applied in the manufacturing process of circuit boards in fields such as communication equipment, automotive electronics, and industrial control, helping the industry achieve the transformation from 'manufacturing' to 'intelligent manufacturing'.
