Application field of conformal coating
conformal coating can provide protection for electronic circuits in household appliances, making them resistant to harmful substances such as water, moisture, insects, etc. in offices and homes. It can be applied to soybean milk machine, coffee machine, Induction cooking, dryer, dishwasher, air conditioner, computer, bathroom electronics, electric car, etc.
The automotive industry requires conformal coating to protect circuits from the hazards of several situations, such as gasoline evaporation, salt spray, brake fluid, etc. The application of electronic systems in automobiles is constantly growing rapidly, so the use of conformal coating has become a basic requirement to ensure the long-term reliability of automotive electronic devices. For example: computer control systems, air conditioning, automotive electronics.
Due to the unique nature of the usage environment, aviation, aerospace, and navigation environments have strict requirements for electronic equipment, especially under fast pressurization and decompression conditions, good circuit performance must still be maintained. The pressure resistance stability of anti paint is therefore widely used. For example, satellite systems, military control systems, flight route control systems, navigation systems, and radar control systems.
conformal coating can protect electronic equipment from water, moisture, external chemicals, and special environmental erosion, ensuring its continuous stability. Its application range is very broad. For example, LED display screens, LED guardrail tubes, solar energy, instruments, power supplies, frequency converters, consumer electronics, anti-theft and fire alarm devices, etc.
