Switching power supply is a very important power equipment, which has a wide range of applications in industry, household, medical and other fields. However, the working environment of the switching power supply is often harsh, full of factors such as moisture, dust and chemical corrosion, and these factors will have a great impact on the working efficiency and life of the power supply. Therefore, in the production process, in order to improve the durability and reliability of the switching power supply, it is very necessary to paint a layer of conformal paint on the surface of the power supply.
First of all, the three anti-paint can effectively isolate the external moisture and dust, and ensure that the components inside the switching power supply will not be corroded and worn. If the switching power supply is not painted with conformal paint, it will work in a humid and dirty environment, and the internal components will be easily oxidized, deformed and damaged, which will cause power failure and failure, thus affecting normal use.
Secondly, the conformal coating can prevent short circuit and leakage of power terminals. Switching power supplies often have problems such as moisture and pollution at the terminals, which can easily cause short circuits or leakage of the terminals, increasing the safety hazards of the power supply. The three anti-paints are coated on the terminal, which can effectively isolate the contact between the terminal and the external environment, and ensure the safety and reliability of the power supply.
Finally, the three anti-paints can enhance the mechanical strength of the switching power supply. Switching power supplies usually need to go through long-term operation and harsh working environments. If the casing of the power supply is not strong enough, it will be easily affected by mechanical shock and vibration. The three anti-paints can increase the hardness and wear resistance of the shell, thereby effectively improving the mechanical strength and shock resistance.
To sum up, brushing the conformal paint is a necessary step to ensure the normal operation of the switching power supply and prolong its service life. In the production process, we should strictly follow the national standards and quality requirements, choose high-quality conformal paint, and ensure that the paint layer is uniform and smooth to ensure the reliability and safety of the switching power supply.
