SuZhou Tonkida Electromechanical Technology Co., Ltd Professional SMT whole line supplier

First, the placement machine patch missing paste, throwing material situation

1. First of all, we need to check whether the feeder of our components is in place

2. Suction nozzle problem: If the suction nozzle is blocked and damaged, it will affect the suction and vacuum suction of our suction nozzle, and the suction of the suction nozzle will be damaged, and the situation of poor absorption and poor installation will occur.

3.PCB board (substrate) problem: Sometimes our PCB board does not move normally, or the solder paste is too little, and the nozzle cannot be correctly mounted in place when mounting. Or after the installation in place after the movement appears usurpation.

4. Program problems: we do not set the program correctly, which will also lead to the situation of throwing material, so we must configure the program of the placement machine before using it.

Second, the placement machine patch over, side parts of the situation

1. Transportation problem: The feeder is abnormal when distributing the components

2. Height problem: the height of the mouthpiece of the placement machine or the height of the grab material is incorrect.

3. Component problem: the loading hole of the component is relatively large, so it will lead to the situation of the component flipping

Third, the placement machine patch offset

1. Location problem: the X-Y axis coordinates we set when programming the placement machine are not correct;

2. Suction nozzle problem: If our suction nozzle is damaged and cracked, the vacuum pressure in the suction nozzle will be damaged, making the suction unstable.

4. The damage of the patch component of the patch machine

1. Position problem: If the positioning thimble set in the programming is too high, it will cause collision or damage during the mounting process of the mounter, and the same Z-axis will also occur if the coordinates are set incorrectly.

2, the suction nozzle problem: if the suction nozzle is not sensitive enough, there may be a phenomenon of the suction nozzle stuck, so that we will also have damage.
