QDD400 connector uses 3D to detect the flatness of welding feet, which is the key quality control step to ensure the stable transmission of 400G high-speed signals. Any minor poor connection may lead to serious signal problems.

In modern automated production line (SMT), the mounting precision of components is extremely high.

1. Prevent mounting failure: If the flatness of the welding foot of the connector itself is too poor, some pins may be damaged due to too much stress when the Mounter presses it onto the PCB, or due to inconsistent height, it is impossible to completely contact the solder paste.

2. Improve welding yield: before reflow soldering, ensure that all pins are in good contact with solder paste, which is the premise of forming reliable solder joints. As a key link of incoming materials or process inspection, 3D inspection can effectively intercept defective products and prevent them from entering subsequent processes, thus improving the overall production yield and reducing costs.
