PCBA circuit boards can be exposed to moisture for a variety of reasons. First of all, liquid contact is one of the major hidden dangers, whether it is direct water, other liquids or humid environments, may be due to incomplete sealing of the device shell or interface, resulting in moisture penetration into the device interior, which in turn causes damage to the circuit board. Secondly, high humidity environment is also a common cause of moisture PCBA circuit boards, especially in the bathroom, open-air areas, such as long-term exposure to high humidity in the electronic equipment, if the lack of appropriate protective measures, PCBA circuit boards are very susceptible to moisture. Finally, liquid splash is also a risk that can not be ignored, such as the interior of the washing machine, near the pool and other environments, electronic equipment may be accidentally subjected to liquid splash, resulting in moisture on the circuit board.

1, safety hazards:

Function Setting: Moisture circuit boards may cause some or all of the functions of the device to fail, such as the screen, buttons, sound, etc., affecting the normal use of the device.

Risk of electric shock: contact with moisture PCBA circuit board increases the risk of electric shock, posing a potential threat to the user's physical safety.

Short circuit and overheating: Moisture circuit boards may trigger short circuits, leading to overheating of the device, or even cause a fire.

2. Recommendations for use:

Power Disconnection: Disconnect the device from the power supply as soon as it is found to be damp and avoid further use to minimize the risk of further damage.

Sensing the battery: For devices that can sense the battery, such as cell phones, will accelerate the removal of the battery, battery damage or overheating.

Drying Treatment: The device can be left to dry naturally in a well-ventilated area. The use of a moisture absorber or a device-specific drying bag will help remove moisture faster.

Professional Repair: If the equipment cannot be repaired by itself or does not work, professional repair service should be sought. It is not recommended that users do their own maintenance or repair to unlock the problem.

Preventive Measures: For devices that are susceptible to moisture, consider using a protective cover, storing them in a dry place or avoiding exposing them to moisture.

So according to the above once the PCBA board is found to be damp, no matter what the reason behind it is, it will bring a series of safety hazards and usage problems. In order to ensure the safety of the equipment and users, we must act quickly, including but not limited to immediate power off, drying treatment and seek professional maintenance services. At the same time, the importance of preventive measures should not be overlooked, they can effectively avoid equipment moisture, thus extending the life of the equipment and reducing potential risks.
