The electronics used in aerospace applications have similar requirements to those used in the automotive sector, but aerospace PCBs may be exposed to even harsher conditions. PCBs may be used in a variety of aerospace equipment including planes, space shuttles, satellites and radio communications systems.

Aerospace PCB manufacturing requires using materials that can withstand high amounts of vibration, extreme temperatures and other harsh conditions. Some aerospace PCBs even need to be able to perform in outer space and must be extremely durable. Boards made with lightweight materials such as aluminum are also beneficial for use in aerospace. Anodized aluminum may be used to increase resistance to oxidation.

Some uses for PCBs in the aerospace sector include:

Power supplies: PCBs are a key component in the equipment that powers a variety of aircraft, control tower, satellite and other systems.

Monitoring equipment: Pilots use various kinds of monitoring equipment, including accelerometers and pressure sensors, to monitor the function of the aircraft. These monitors often use PCBs.

Communication equipment: Communication with ground control is a vital part of ensuring safe air travel. These critical systems rely on PCBs.
