Aerospace Printed Circuit Board (PCB) Manufacturer

Aerospace PCB Manufacturer

We use circuit boards every day, and they’re essential to most of our electronics. Our gadgets don’t usually have to endure any extreme temperatures or radiation though. When it comes to printed circuit boards for the aerospace industry, they need to be able to withstand a lot more.

Unlike most traditional PCBs, printed circuit boards used in aerospace applications are subjected to extreme environmental conditions, radiation, chemicals, contaminants, and more. Therefore, When it comes to designing printed circuit boards for aviation, quality assurance is not optional. Unitepcb has made the investments in terms of both manufacturing equipment and manufacturing expertise that focuses on the high performance, reliability, and extreme environmental tolerances required for these industries.

Printed Circuit Boards in Aviation

Printed Circuit Boards in Aviation

In the aerospace industry, a wide range of PCBs are used, such as rigid 1,2-sided, standard multilayer, flexible, rigid-flex, and HDI/Microvia/Build-up/ IC Substrate, depending upon the applications, like power supplies, power converters, radio communication, engine control systems, radars, health monitoring sensors, etc.

The aerospace industry is shifting focus towards the usage of advanced materials in order to make the aircraft lightweight yet durable with an ultimate aim to enhance fuel efficiency. PCBs used nowadays are experiencing miniaturization of components in order to establish weight and space savings. The aerospace industry requires sturdier PCBs so as to withstand harsh conditions. Some of the key properties of PCBs targeting aerospace applications include high-temperature resistance, shock absorption, high durability, and reliability.

Here’s how aerospace circuit boards withstand some of the harsh conditions they’re exposed to.

High Temperatures

In outer space, electronics could be exposed to temperatures as low as negative 150 degrees Celsius. In the vacuum of space, there is also no air to transfer heat, so the only way to transfer it is through radiation.

Manufacturers use certain high-temperature laminates, copper and aluminum substrates in aerospace PCBs so that they can survive these extreme temperatures. Thermal compound is also often used to insulate heat from transferring to other electronic parts.

Components may be set approximately 20 thousandths of an inch from the board’s surface, or space may be used to facilitate thermal dissipation of heat. In aviation, fans may be used to get rid of extra heat.

Heat can also lead to oxidation. Using anodized aluminum can eliminate the problems that this might cause.

Shock Absorption

Electronics used in the aerospace industry can also be exposed to mechanical abuse like excessive shock and vibration.

So that PCBs can withstand these kinds of conditions, manufacturers sometimes alter the design of the boards. Some use pins that are pressed into the board to help hold components in place, as opposed to using soldering. Sometimes, engineers combine pins and soldering for additional security.

Some of the strategies for making PCBs more resistant to high or low temperatures also have applications for protecting against shock and vibrations. Applying thermal compound to a board can help reduce the impact of fluctuations. Leaving a small space between components and the surface of the board can also create some relief of the stress on the PCB.


PCBs used in outer space have another somewhat unique challenge to overcome. The higher levels of radiation in space can cause damage to equipment if it’s not suited to tolerate its effects.

Manufacturers attempt to shield electronics from radiation using various materials. They also make components smaller, so that are fewer pieces that risk radiation. They also build in backups so that a single radiation event doesn’t disable an entire operation.

Antifuse technology, which creates permanent routes that can conduct electricity between transistors, has been found to be more resistant to radiation. Other types of circuits have been made more resilient by using thinner layers of material.

Radio Frequency

In aviation, radio waves must be used to communicate, so it’s crucial that signals can be transmitted without becoming degraded in any way.

To make sure that radio communications get through properly, manufacturers must place shielding in strategic places on the PCB and sometimes use antennas. Making transmission lines as short as possible can also help ensure that radio communications are correctly transmitted.
