Different angles of RGB light source irradiation, accurately reflect the slope information of the surface of the object, so that the solder joint layer is more obvious, clearly showing the solder defects.

Based on big data +AI deep learning algorithm training, covering more than 97% of solder joint models, realizing automatic identification of solder joints of the whole board, and configuring detection algorithms to automatically adjust parameters.

The model based on big data training has strong detection ability and generalization ability, which can correct the alarm caused by the diversified deviation of solder joints, and solve the problem of missing and false alarm caused by the large change of solder joints components and the easy effected of pins and devices.
