    Aerospace PCB: The Ultimate FAQ Guide

    You would need a highly reliable printed circuit board that can perform under extreme conditions for aerospace PCB.

    The aerospace industry is highly particular and critical, and even the slightest quality issue can endanger hundreds of human lives.

    Our clients ask us about quality, strength, and many other aspects of aerospace PCB. That’s why we came up with this complete FAQ guide on aerospace PCB.

    What Is Aerospace PCB?

    In electronics manufacturing, circuit boards are mandatory. The engine of every electronic appliance is made with PCB and its components. A PCB directs electrical charges integrated for seamless functions.

    Aerospace PCB

    Aerospace PCB

    As the name suggests, aerospace PCBs are those you would see in the aerospace industry. It is also used in military war crafts and also uses aerospace boards.

    As you can understand, this industry is susceptible and has potential risks of severe casualties. The aerospace PCBs should have unique features.

    The aerospace circuit board must be highly durable, shock-absorbing capability, humidity resistance, etc.

    What materials should be used in aerospace PCB also depends on the type of the application.

    As airplanes can be exposed to extreme temperatures, copper, aluminum, laminates substrates are widely used in aerospace PCBs.

    What Are the Types of Aerospace PCB Based on Number of Layers?

    Based on the number of layers, you would see three types of aerospace PCBs. They are:

    1. One-Sided PCB

    In a single-sided, or single-layer PCB board, you will find the mounted components on one side of the board. They are the most basic type of aerospace PCB and are used to build circuits for surveillance machines and switching relays.

    2. Two-Layer PCB

    In two-sided or double-layer PCBs, you will have two layers of mounted components. They are more advanced than single-sided aerospace PCBs and are widely used in manufacturing power supply devices. You can see a double-sided PCB in LED lighting also.

    3. Multilayer PCB

    Multilayer PCBs are the most complex type of PCBs. These PCBs contain more than two layers (at least 3) of conductive materials.

    Multilayer Aerospace PCB

    Multilayer Aerospace PCB

    These boards provide the designer more flexibility to add functionalities to the devices. Moreover, they are also used in devices with GPS technology for the aerospace industry.

    What Industry Standards Are Applied to Aerospace PCB Development?

    The following industry standards are applied to aerospace PCB development

    ISO 9100 – This is a globally recognized ISO (International organization of standardization) QMSs baseline to derive other standards. This standard is open to any organization for customer satisfaction. QMS processes, higher management responsibilities, and ongoing improvement.

    Aerospace PCB manufacturer must be ISO certified

    Aerospace PCB Manufacturer Must Be Iso Certified

    SAE or the Society of Automotive Engineers also introduced a set of standards for aerospace PCB development. They are:

    AMS2750E – This standard covers the device’s pyrometric requirements: instruments, thermals sensors, thermal processing appliances, and assessment: observing and investigating to confirm coherence to heat treatment specification.

    AS478N – Defines the marking type and where to locate them for aerospace components.

    AS5553A – This standard sets the general requirements for every organization in the supply chain (integration and procurement).

    AS9006A – Determines software and other supporting components of the software. This also includes any devices or components that can be a part of the software or uploaded to the aerospace system.

    AS9100D – Determines the QMS conditions for aerospace industry suppliers. It also covers the manufacturing process (in-house or outsourced), customer satisfaction, and management responsibilities.

    AS9101E – Covers the QMS guidelines for reporting and auditing.

    AS9102B – List’s baseline FAI (First article inspection) criteria.

    ** Other standards or guidelines developed for multiple industries are not listed above.

    From the above list, you can see that significant industry standards are applied to the aerospace industry’s electronic component manufacturing process. But which standard controls which part of the manufacturing? For better understanding, we have created a table describing which standards are used in which manufacturing process.

    What Are the Types of Aerospace PCB Based on Design & Function?

    Here is the list of most common aerospace PCBs that you can see in most applications:

    ● Rigid PCB

    You can never twist or fold a Rigid PCB into another shape. You will find rigid PCBs in auxiliary power units. Cockpit instruments of an airplane, temperature sensors, and power converters use rigid PCB.

    Moreover, they are widely used in manufacturing control tower instruments.

    ● Flexible PCB

    As the name suggests, flexible PCBs are flexible, and you can twist them easily. They are made of plastic substrates like polyimide. They are widely used as connectors in different applications in the aerospace industry.

    ● Rigid-flex PCB

    Rigid PCBs use both flexible and rigid board technology. These PCBs come with minimal weight and occupy less space. The features of Rigid PCBs make it an ideal choice for the aviation industry.

    ● RF PCB

    In the aviation industry, radiofrequency PCBs are mandatory. They are responsible for making communication devices that pilots use for seamless communication.

    ● High-Speed PCB

    Physical features of high-speed PCBs such as layout, packaging, and interconnection impact signal integrity.

    High speed Aerospace PCB

     High-Speed Aerospace PCB

    The aviation industry uses high-speed PCBs to manufacture those communication devices that are considered highly reliable.

    ● Metal Core PCB

    In the metal core PCB, you will see metal at the core. Mostly aluminum, copper, and steel alloy are used in metal core PCB. These PCBs can manage heat very efficiently, and aviation industries use them to increase heat dissipation.

    ● Aluminum PCB

    Aluminum can dissipate heat very efficiently and does not cost more. In the compression and decompression process, airplanes generate a considerable amount of heat, and aluminum PCB boards disseminate them.

    ● HDI PCB

    High-density interconnects, or HDI PCBs can make lighter and faster products. These PCBs can integrate Microvias leveraging blind vias.

    What Are the Features of Aerospace PCB?

    Before you invest in aerospace PCB, you should know the features very well. Here are the characteristics of Aerospace PCBs.

    Handles Extreme Conditions Efficiently

    As we have described earlier, you need solid PCBs for the aerospace industry. They should be more sturdy than the standard PCB you see in typical electronic devices.

    Boeing Plane

    Boeing Plane

    Aerospace devices deal with lots of heat, and the copper and aluminum substrates with high-temperature laminates tackle that temperature. For proper heat transformation, you will also see thermal compounds in an airspace PCB.

    Reliable PCB Material

    Manufacturers integrate additional features in the fabrication and design process of aerospace PCBs. For heat dissipation, they apply thermal compounds, for example, aluminum.

    Critical traces have to be grounded or shielded. As they are open to hostile situations, manufacturers spray them with acrylic spray.

    Withstand Shock

    In the aerospace industry, extreme vibration and shock are common phenomena. Manufacturers alter the board’s design to counter those vibrations and shocks.

    Here you will see pins instead of soldering. This way, the board holds its component tighter. Sometimes both pin and soldering are applied.

    Reliable and Durable

    The most crucial factor of aerospace PCBs is reliability. Aviation electronics have to go through an aggressive environment, and they have to transmit satellite signals without interruption or failure.

    Aerospace PCBs should be durable and reliable

    Aerospace PCBs Should Be Durable And Reliable

    Consequently, the aerospace PCBs are built with sturdy substrates, and manufacturers pin or solder the components firmly on the top of the board to stay there intact for a long time.

    Can Withstand Radiations

    Outer space PCBs have to face a high level of radiation, and that can damage the PCB board easily.

    On that account, the design of Aerospace PCBs must be radiation preventive. To achieve that, manufacturers apply anti-fuse technology, which enhances radiation tolerance.

    Can Tackle Varying Frequencies

    The aviation industry depends on radio waves for communication purposes. And Those signals must be transmitted regardless of the environment or situation.

    The antenna and strategic places need to be shielded. The transmission lines are shorter to establish constant transmission.

    Rust Resistant

    Manufacturers cover the exposed copper area with an invisible coating, including solder masking and aerosol coating.

    Epoxy coatings are also used sometimes because they can create practical barriers to oxidation resulting in corrosion.

    The coating must tolerate the thermal specification of the aerospace PCB.

    Withstands Aerospace Standards and Protocols

    Aerospace PCB manufacturers have to meet the standards. We have mentioned the criteria earlier in this article. Every aerospace manufacturer has to maintain those standards in every layer of the manufacturing process.

    Optimizing Capability

    After tackling the fluctuating temperature, the aerospace PCB also has to be corrosion resistant. Manufacturers have to use suitable materials to achieve that property.

    What Does a Manufacturer Do to Make an Aerospace PCB Work in the Extreme Temperature of Space?

    In outer space, devices have to endure temperatures as low as minus 150 degrees Celsius. Apart from that, in space, there is no air that will transfer heat. In that case, only radiation can transfer heat.

     Aerospace PCB can work in minus 150 degree C

    Aerospace Pcb Can Work In Minus 150 Degree C

    Manufacturers utilize unique high-temperature laminates, aluminum, and copper substrate in an aerospace PCB to tackle this situation. Manufacturers also use some thermal compounds so that heat can not transfer to other electronic parts. Components are twenty-thousandths of an inch distant from the surface of the board. Fans are also used to disseminate extra heat.

    What Design Standards to Follow for Designing Aerospace PCB?

    For making an aerospace PCB more robust, there are specific design and layout considerations to follow.

    Aerospace PCB cercuit diagram

    Aerospace PCB Circuit Diagram

    You have to utilize the appropriate mil-spec components. You will also have to consider current, among other crucial factors, and design additional cushions accordingly.

    • First, you have to secure the additional current that the PCB circuitry will generate.
    • You have to design the PCB in such a way that it can carry additional amperes if the other two fail.
    • Assign the aspect ratio to deal with the bare board’s balance according to the vias when you drill the latter. The ratio should be 1:10; if you exceed that, that will endanger the reliability.
    • When designing, you have to separate the ground planes and power. You have to separate low and high-frequency ones.
    • Oscillating components are likely to produce waveforms when using those at high frequencies and can affect lower frequency components.
    • Shield and make sure the clock signals are clean. You can use aluminum or similar materials to achieve that.
    • Now you have to verify the impedance calculations. As you can not test aerospace applications in a familiar environment, you must run pre-layout simulations.
    • You have to use simulation software to make it possible. Thus you will be able to achieve standard recommendations or alter the design accordingly. And you will be able to know whether your PCB is working optimally or not.
    • Maintain a strict 45-degree angle in the process of trace routing your aerospace PCB. Curved traces can transmit currents within the circuitry smoothly, which is why they are mostly preferred.

    You have to do cushioning to the mechanical holes for strength and efficiency.

    You can use FR4, G10, or Cyanate Ester for low-frequency applications. For high frequency, you have to use the Rodger series, Droids, and Teflon-based materials.

    What Is The Fabrication Process Of Aerospace PCB?

    The fabrication process of aerospace needs some unique treatments compared to the standard PCB fabrication process. You have to perform some additional developments in every stage of traditional PCB fabrication. Here are the steps:

    • Sequential Limitation– You have to complete this process with polymer matrix composites. They are light and stiff but resistant to heat.
    • Blind and Buried Vias– You will use these to connect PCB layers to connect the outer and inner layers. Buried vias connect outer layers without penetrating them.
    • Filled Vias – You have to use non-conductive and conductive filled vias to protect them from solder or other contaminations. It also works as structural support to the copper pad.

    PCB fabrication

    PCB Fabrication

    • Stacked Vias and Laser Drilling – Laser drilling is essential in the aerospace industry to create vias. It is also applicable for composite materials and FR4.
    • Heatsinks– For insulting the heat sinks, you have to use high-grade thermal compounds. This process is vital for pad PCB boards and ensures lesser vibration.
    • Castellation and Edge Plaiting –
    • Edge Plaiting and Castellation – This allows aerospace PCB’s modification. You can drill a hole more efficiently and create milling slots.
    • Thermal Compound Application – As thermal compounds insulate heat sinks, you have to apply them. Aerospace PCBs can be exposed to different temperature levels.
    • Soldering of swages– You have to use this in the soldering of aerospace PCB.
    What Is the Assembly Process of Aerospace PCB?

    Some of the processes of aerospace assembly are as follows:


    For perfect execution in the manufacturing process, the planning and designing phase is crucial. You should follow every step carefully in the design and layout process.

    You have to check every specification that can cause flaws.

    Solder Paste Application

    You have to apply solder paste on the board. Stencils are used here to create different sizes and shapes.

    Aerospace PCB assembling

    PCB Assembly

    Components Placing

    This automatic process enables component placement on the board’s targeted areas. Robotics machines are used in this process as they are operated by software.

    Solder Paste Application

    You have to apply solder paste properly after you are finished with component placement. Conveyor belts are used to put through the aerospace PCB and go through a reflow oven. You have to use a standard industrial oven to augment the excess solder paste melting.

    Then they are revealed to cooler heaters to cool down and solidify melted paste and hold the board’s component firmly.


    At this step, you have run an inspection to identify any functionality issue. A Poor quality connection can lead to an operational flaw. The first check is done manually, and then digital machines are used.

    Component Insertion

    Through-hole insertion is required for aerospace PCB components because the aerospace industry primarily uses multi-layered PCBs. This process ensures the signals can pass through from one side of the board to the other side.

    Final inspection

    In the final stage, you have to check the electrical properties and functionalities. This process includes current and voltage inspection. Single outputs are also considered in this inspection. As the plane can be exposed to various risks, any flaw in this stage can be disastrous.


    Cleaning the aerospace PCB is crucial as any residue can interfere with the functionality and cause harm. You have to use deionized water to wash the board and dry it with compressed air.

    How To Test Aerospace PCB Assembly?
