In a humid environment, PCB circuit boards are prone to various problems, such as short circuits, circuit board signal open circuits, etc., so how to judge whether the PCB circuit board is damp?
If the PCB circuit board is used in a humid environment, because the air contains a lot of moisture, when the humidity is too high, it will become water droplets and fall on the PCB circuit board, and the water droplets will fall on the PCB wire board. Once the water is on the circuit board, the water vapor can easily adhere to the pins or printed wires of the electronic components.
If the printed line is wetted by water droplets, especially the signal transmission line is relatively small in size. After a period of water vapor, the printed lines will be moldy and broken, causing the circuit board to be short-circuited or even burned when the circuit board is energized.
There are three reasons for the failure of the circuit board caused by damp.
1. Changing the circuit parameters of the PCB circuit board will cause the PCB board to fail.
2. The pcb circuit board circuit is short-circuited, causing the pcb circuit board to malfunction.
3. The signal processing of the PCB circuit board or the disconnection of the transmission line leads to the failure of the PCB board.
