how to solve the problem of using the inverter in a humid environment

In March 2020, we received a inquiry from a Philippine customer. He said that the Philippines has many islands and the weather has high temperature, rainfall, high humidity and high salt content, which is easy to corrode electrical circuit board products. The customer asked us if there is any way to solve it. The inverter is used in an environment with high humidity and salinity, which can prolong the service life of the inverter and reduce failures caused by environmental problems.

 

After receiving the customer's consultation and understanding the actual use of the customer, we especially focus on the environment of high dust, salt spray, humidity and high temperature in Southeast Asian countries and transportation vibration. The circuit board may cause corrosion, softening, deformation, mildew and other problems. , causing circuit board failure.

We tell the customer that our inverter circuit boards are protected by conformal paint, and tell him why the conformal paint is used and what problems the conformal paint can solve.

The conformal paint is coated on the surface of the circuit board to form a layer of conformal protective film.

 

If the inverter is not used with three-proof paint due to transportation vibration, humid environment, high salt content, and high temperature, the circuit board may be easily corroded, mold growth and short circuit, etc., resulting in circuit failure. Use three-proof Paint can protect the circuit from damage, thereby improving the reliability of the circuit board, increasing its safety factor, and ensuring its service life.

Because the radiators, high-power diodes, cement resistors, buzzers, tact switches, relays, sockets, pin headers, light-emitting diodes (non-indicating), and LCD displays on the circuit board of the inverter are Can not be painted, all of our circuit boards are manually coated with conformal paint to ensure the quality of the product.

 

After listening to our detailed explanation, the customer ordered 50PCS samples from us. After one year of use test, he ordered 1000Pcs inverters and 1000PCS controllers from us in 2021.
