Aerospace PCB Assembly: From Designs to Selecting Suppliers

Exploring space and beyond Earth’s limits, the aerospace industry is getting more advanced. In aerospace applications, PCB plays a vital role. It handles the operation of any system. It also provides the electrical and mechanical support between various electronic components. IoT and electronics have become even more important with the increased aerospace business. Aerospace PCB assembly requires precision, reliability and proper planning.

This article provides brief information on the importance of PCB in aerospace applications.

Applications of Aerospace PCB Assembly
Aerospace PCB assembly is used in technology and equipment across the aerospace industry. They should function fully in extreme operating conditions. This includes highly radioactive conditions, outer space, and extreme temperatures. The PCB assembly must withstand high-speed movement, vibrations, and impact. It must also withstand the conditions during takeoff and landing. 

Some of the applications of Aerospace PCB assembly include:
Temperature sensors
Communication systems
Radar Installations
Satellite Technologies
Battery Management Units (BMS)
Flight Instruments and Equipment, etc.
Benefits of Aerospace PCB Assembly
PCB assembly plays a significant role in aerospace applications. It provides reliability and precision. Some of the benefits of Aerospace PCB Assembly includes:

Precision Engineering
In the aerospace industry, accuracy and precision are crucial factors. The electronic components in aerospace must resist harsh environments. In the aircraft sector, intricate designs and careful soldering are vital for building printed circuit boards (PCBs). This is necessary to ensure that the circuitry operates under challenging circumstances. Aircraft require precision engineering to avoid fatal mistakes. 

Withstand Harsh Conditions
PCB manufacturers use copper and aluminium for high-temperature laminate substrates. This helps the boards survive extreme temperatures. Similarly, to mitigate the radiation, specialised materials are used. 

Redundancy and Reliability
Designers and developers create aerospace units with backup options. Even if any components fail, there are backups. PCB assembly is crucial for designing redundant systems. It makes sure they operate smoothly, even if a component fails. To cut the risk of failure, rigorous testing and quality control measures are implemented during the entire PCB assembly process.

Design Factors of Aerospace PCB Assembly
In the aerospace PCB assembly environment, design factors are critical for optimal performance and reliability. Some of the critical design factors include:

Compliance with IPC Class 3 standards
These standards are designed for electronic devices to operate in harsh environments. It includes extreme temperatures and exposure to corrosive chemicals. Heat resistance materials like AP, Pyralux and FR408 are some of the common choices for metal components. 

Frequency Compatibility
Aerospace PCB is a mix of both low and high-frequency components to prevent interference. Thus, designers should design PCBs to differentiate the frequencies. This way, high-frequency components won’t interfere with signals from low-frequency components. Besides, the clock signal-generating components require additional shielding with the enclosure aluminium materials.

Material Selection
The aerospace environment can experience harsh conditions, including high temperatures, moisture and vibration. Thus, the manufacturer must choose a substrate like copper laminates or aluminium for strength. They may also consider ENIG and immersion silver. Besides, selecting materials with a low coefficient of thermal expansion will minimize the change in size from temperature fluctuations. 

Shock Absorption
Aerospace devices are prone to mechanical vibrations. Therefore, shock-absorbing materials, like conformal coatings, should be used to protect the components from vibrations. 

Surface Finish
Aerospace PCBs experience vibrations, moisture, and extreme temperatures; thus, they require a protective surface finish. During PCB assembly, apply a coating to prevent oxidation and corrosion. Also, the use of thermal compounds helps to insulate the heat sinks. 

Electromagnetic Shielding
PCB manufacturers should incorporate EMI shielding. This includes proper routing, grounded planes, and shielding enclosures.
