The General Definition Of PCB Layer Deviation
Layer deviation refers to the difference in concentricity between the layers of the PCB board that originally required alignment. The scope of its requirements is controlled according to the design requirements of different PCB board types. The smaller the hole-to-copper distance, the stricter the control, to ensure its ability to conduct and overcurrent.
Commonly used methods to detect layer deviation in the production process:
At present, the method commonly used in the industry is to add a group of concentric circles to the four corners of the production board, set the spacing between the concentric circles according to the requirements of the production board layer deviation, and pass the X-Ray inspection machine or X-drill during the production process. The target machine checks the concentric offset to confirm its layer deviation.
