Because it is made using electronic printing, it is called a "printed" circuit board. After the electronic components are welded on the PCB board, the thickness of the PCB board changes. In order to be suitable for the use of the manufactured products, the thickness of the entire PCB board needs to be tested to confirm whether the thickness of the PCB board is within the design requirements. At present, there is no one A fast and effective inspection method can detect the thickness of the PCB board.
