SMT placement processing is a combination of multiple process procedures. SMD is through the pick and place machine to mount the components to the PCB pads on the specified location, and this process may appear component displacement problem, component displacement in the subsequent welding process will appear welding quality problems, so today combined with the actual situation to tell the SMT placement processing in the component displacement of the reasons for analysis.
1. SMT suction nozzle air pressure is not enough or suction nozzle wear, resulting in the placement pressure is not enough, resulting in the displacement of components.
2. SMD machine SMD program programming has a mistake, such as material level deviation, thus leading to mount offset.
3. The mounting machine is old, the camera recognition rate is low, the mounting accuracy is reduced.
4. the mounting machine camera has dirt, leading to recognition deviation.
5. The solder paste stickiness is not enough, the component shakes on the mounting flow guide causing the component to shift.
