Choose high-quality materials:
In the aviation industry, reliability and durability are must-have requirements. In such applications, the circuit must operate continuously and without failure for long periods of time. The general rule is to use high-quality materials and components that will last in the market for a long time.
Correctly determine tolerances:
Tolerance is one of the important items when designing PCB. It ensures that the PCB design has the correct tolerances and has adequate clearances, drill holes and spacing for better heat dissipation.
Use a highly protective coating:
PCB facing materials should be selected to protect against heat, moisture, water and vibration, and withstand the worst conditions. The coating is then sprayed with an acrylic base to protect the final printed circuit from contamination or accidental short circuits.

Strict testing before leaving the factory:
Some aerospace PCBs require rigorous testing in special environments. Some PCBs need to be tested in a vacuum area and at negative temperatures. If PCBs are designed for use in geostationary or low-orbit satellites, they must perform extreme temperature testing to ensure the reliability of the PCB.
- 1.High temperature resistance: Since aerospace electronic equipment is often in a high temperature environment, polyimide (PI) and polytetrafluoroethylene (PTFE) have high temperature resistance.
- 2.Corrosion resistance: There are some corrosive substances in the aerospace environment, which requires the use of materials with good corrosion resistance, such as special polyamides and special coatings.
- Moisture resistance:In a closed environment, humidity can be an issue. Electronic devices and circuit boards can malfunction due to moisture. Such as nano coating, normal temperature fluorine coating, etc.
- Radiation Resistance:Depending on the spacecraft’s location in the Earth’s atmosphere, it may have to withstand radiation or harmful RF. Because these types of interference can wreak havoc on communications and other circuit operations, circuit boards need to be resistant to them, such as boron polyethylene.
- Fire resistance:The aviation industry has strict requirements for fire safety, so it is necessary to use materials with good flame retardancy, such as polystyrene (PS) and Australian flame retardant epoxy resin.
