What are the problems with printed circuit boards in humid environments?
In a humid environment, PCB printed circuit boards are prone to various problems, such as short circuit, circuit board signal open circuit, etc. These faults all exist. How to judge that the PCB printed circuit board is damp?
?
If the PCB printed circuit board is used in a humid environment, 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 that fall on the pcb printed circuit board will fall on the printed circuit board. After spreading out, it will attach to the pins or traces of electronic components.
?
After the printed line is wetted by water droplets, especially the signal transmission line is relatively small. After soaking for a period of time, the printed wiring will become moldy and broken, causing the board to be inoperable the second time it is put into work
There are three reasons for printed circuit board damp failure:
1. Changes in circuit parameters in the pcb printed circuit board lead to pcb board failure;

2. The circuit in the pcb printed circuit board is in a short circuit state, causing the pcb circuit board to fail;
3. The signal processing of the pcb printed circuit board or the transmission line to be disconnected, causing the pcb board to fail.
