Moisture-proof treatment methods for the internal circuit board of the charger

Moisture-proof treatment of the internal circuit board of the charger is the key to ensuring the stable operation of the equipment. The following are some recommended treatment methods:

Encapsulation with moisture-proof materials: Attach sealing strips or moisture-proof tapes around the circuit board, or use substrate materials with moisture-proof performance to enhance the moisture-proof ability from the source.

Carry out moisture-proof coating treatment:

Apply moisture-proof paint: Use special moisture-proof coatings such as moisture-proof paint, moisture-proof glue or three-proof paint to form a protective film on the surface of the circuit board, effectively preventing the intrusion of moisture.

Special coatings are used, such as Parylene nano waterproof and moisture-proof coating, which has excellent dielectric and shielding properties and can meet the various protection requirements of circuit components.

Control environmental humidity

Storage environment: Store the charger in a dry and well-ventilated place, avoiding damp areas. Equipment that is not used for a long time can be placed in a moisture-proof box and desiccant added.

Usage environment: In seasons with high humidity, indoor humidity can be regulated by air conditioners or dehumidifiers. For occasions with high moisture-proof requirements, circuit boards can be installed in sealed enclosures or cabinets, and humidity control devices can also be installed.

Strengthen daily maintenance

Regular inspection: Regularly check the sealing condition of the charger to ensure that there are no gaps in the casing. For equipment used in damp environments, increase the inspection frequency.

Timely cleaning: After outdoor electronic devices are used in rainy days, the surface moisture should be wiped with a dry cloth in time and they should be placed in a dry and well-ventilated area to dry.

Optimize the circuit board design

Reasonable layout: Avoid overly dense components and ensure sufficient heat dissipation space to reduce the accumulation of moisture on the board.

Open ventilation holes: Open an appropriate number of ventilation holes on the circuit board to promote air flow and reduce the accumulation of moisture.

Install temperature and humidity sensors: Install temperature and humidity sensors inside the charger to monitor environmental conditions. Once the temperature and humidity reach the preset threshold, corresponding countermeasures can be taken, such as activating the heating device to raise the temperature or using a fan to remove moisture.
