Product Description
The main technical route of solder joint inspection is quantitative defect inspection, which can detect whether there is welding, cold welding, short circuit, Solder bridge, solder insufficient, excessive solder,solder projections,etc.
It can calculate the arc, volume and tip height of solder joints.

Technical Features
Five-axis visual positioning
MARK point visual positioning is used to support XYZRA five-axis position offset calibration, greatly improving the versatility of the equipment.
The cognitive visual inspection technology used in the inspection system integrates industrial robot control technology, high-speed industrial photography technology, computer vision technology, AI algorithms based on deep neural networks, and machine learning technology.Through standardization, automation, and intelligence, it provides end-to-end It realizes all-round appearance quality inspection on the end, and is used in solder joint visual inspection, coating visual inspection, dispensing visual inspection and PCB finished product inspection, etc.
Solution
2. AI intelligent detection engine for detection: Submit the collected photos to the AI intelligent detection engine for detection. The efficient algorithm supports detection within 1 second.
3. Detection of unqualified solder joints - Based on statistical analysis of data, the solder joints detected using AI intelligence are verified and compared the unqualified solder joints detected by traditional human eyes.
