How does the PCBA factory ensure the accuracy of the SMT machine?

PCBA processing factories mainly use the following 5 methods to ensure the accuracy of the placement machine:

1. Regular cleaning:

The placement machine will produce dust, oil and other impurities during operation. These impurities will affect the accuracy of the placement machine. Therefore, the placement machine should be cleaned regularly, especially the nozzle filter and other mechanisms.

2. Regular calibration:

The accuracy of the placement machine will decrease with the increase of usage time. Therefore, the various parameters of the placement machine should be calibrated regularly to ensure its accuracy.

3. Maintain the transmission system:

The transmission system is the core component of the placement machine and directly affects the accuracy of the placement machine. For example, the servo system of the XY axis, the motor grating encoder, etc. must ensure smooth operation. Therefore, the transmission system should be checked regularly to keep it in good condition.

4. Maintain the optical system:

The optical system of the placement machine has a great influence on the accuracy. Therefore, the optical system should be checked and cleaned regularly to keep it clean and in good condition, and there should be a stable recognition system.

5. Maintain the vacuum system:

The vacuum system of the SMT machine has a great impact on the accuracy of SMT. Therefore, the vacuum system should be checked and maintained regularly to ensure its normal operation.
