Best answer

During the PCB SMT patching process, fiducial marks are important tools used to ensure accurate placement and registration of parts. Typically, fiducial PCB markings are required during high-volume assembly to ensure the efficiency and accuracy of the assembly process.

Fiducial marks can be located at specific locations on the PCB, such as the center of part placement or symmetrical locations. These marks can help placement machines and operators determine the correct location and orientation of parts and ensure the stability and accuracy of the assembly process.

In the SMT patching process, fiducial marks can be used in the following aspects:

1. Part positioning: By identifying the fiducial marks, the placement machine can accurately determine the position and orientation of the part and place it in the correct location.

2. Part registration: Fiducial marks can also be used to confirm the registration points of parts to ensure they are aligned with other components on the PCB.

3. Assembly quality control: By checking the accuracy and consistency of fiducial marks, the quality and precision of the assembly process can be evaluated. If any deviations or errors are discovered, corrective measures can be taken promptly.

4. Assembly process automation: Fiducial markers can be used in automated systems, such as machine vision and image processing technology, to help achieve a more accurate and efficient assembly process.

In short, fiducial marks are very important in the PCB SMT patching process, especially during high-volume assembly. They can improve the efficiency and accuracy of the assembly process and ensure product quality and reliability.
