PCB (Printed Circuit Board) humidity detection method, device, medium and equipment

The invention relates to the technical field of circuit boards, and discloses a PCB humidity detection method, device, medium and equipment, and the method comprises the steps: forming a first detection link between the Mth layer and the Nth layer of a circuit board based on a first measurement position communicated with the Nth layer of the circuit board in the PCB and a second measurement position communicated with the Mth layer of the circuit board in the PCB; acquiring a first capacitance value between the Mth layer and the Nth layer of the circuit board based on the first detection link; and judging whether the space between the Mth layer and the Nth layer of the circuit board is affected with damp based on the first capacitance value. According to the scheme, whether the PCB is affected with damp or not is detected through the first detection link in an electrical measurement mode, and the accuracy and timeliness of PCB humidity detection are improved. 本发明涉及电路板技术领域，公开了一种PCB板潮湿检测方法、装置、介质、设备，该方法包括：基于与PCB板
