7.How are 3pdt pcb board small bears protected from moisture and humidity?

PCB (Printed Circuit Boards) are susceptible to damage from moisture and humidity, which can result in malfunction or even complete failure of electronic devices. Therefore, it is necessary to take measures to protect PCBs from these elements.
One way to protect PCBs from moisture is by using a conformal coating. This is a thin layer of protective material that is applied to the surface of the PCB. It acts as a barrier, preventing moisture from coming into contact with the sensitive components on the board.
Another method is to use moisture-resistant materials for the PCB itself. This can include using moisture-resistant coatings or laminates for the board, as well as corrosion-resistant materials for the conductors and connectors.
In addition to these preventive measures, PCBs can also be stored in controlled environments with low humidity levels. This can help to minimize the amount of moisture that comes into contact with the boards, reducing the risk of damage.
Regular maintenance and periodic testing can also help to ensure the continued protection of PCBs from moisture and humidity. By taking these precautions, electronic devices can maintain their functionality and reliability, even in environments with high humidity levels.
