PCB are essential for the aerospace industry

There is no room for error when assembling electronic circuit boards, especially in the military and aerospace industries. These products must be durable, versatile and tough. They must be able to handle all types of needs, have a long service life, and even complete various tasks under the harshest conditions.
 
In order to complete the arduous task, various factors must be considered in the design and electronic PCB assembly process

high temperature
Many people do not know that under certain conditions, the temperature of space may drop to -150 degrees Celsius or even higher. As a result, electronic devices sent into space must be durable enough to withstand high and low temperatures. It should also be noted that due to the vacuum of the environment, heat cannot be transferred through the air in the space. Therefore, heat can only be transferred through radiation in space. Fortunately, aviation PCB manufacturers will only use very specialized aluminum, copper and laminate substrates with high temperature characteristics.


In addition, most aerospace PCBs will be further insulated with thermal compounds to isolate the heat, thus ensuring that the heat is not transferred to other electronic components. In addition, some components are located about one-tenth of an inch from the surface of the board. At the same time, in some cases, space can be used to promote heat distribution. For aviation, fans can be used to eliminate excess heat. Oxidation is also a problem caused by overheating, so anodized aluminum can be used to solve heat-related oxidation.
 
Need shock absorption
Mechanical abuse is also an issue that needs to be considered, because aerospace equipment and components will be subject to vibration and excessive shock. Therefore, some PCBs may need to be modified to withstand such harsh conditions. For example, instead of traditional soldering methods, the pins can be fixed in place by pressing them into the PCB. Or engineers can choose to use soldering and pins at the same time as an additional safety protection measure. In addition, engineers can add thermally conductive glue to the board to reduce the impact of fluctuations on the components.
 
Another strategy to help PCBs handle extremely high and low temperatures, vibrations and shocks is to leave a tiny gap between the surface of the board and the components. In this way, the pressure on the PCB can be reduced.
 
Emissivity
Radiation is another factor that space equipment must be able to deal with. The radiation level in space is higher than that on the earth. Therefore, these panels need to be configured to withstand high radiation levels that can damage space equipment. Engineers can use some special components or materials to protect related electronic devices from radiation. The manufacturing dimensions of the components will also be smaller than normal, making fewer components susceptible to the harmful effects of radiation.
 
RF conundrum
In the aviation industry, radio waves will also need to be used for communication. Therefore, signal transmission must not degrade the quality of the signal. To achieve this goal, engineers can add antennas to the antenna or place shields on certain areas of the board. Keep the transmission line as short as possible so that the radio signal or communication can be transmitted correctly and accurately.
 
Advances in PCB manufacturing technology have enabled the aerospace industry to create space shuttles and probes that can send satellites into the earth and explore deep space. The aerospace industry requires printed circuit boards (PCBs) that are stronger than those required for most conventional electronic equipment.
