The Role of Printed Circuit Assemblys in Aerospace

Printed Circuit Assemblys in Aerospace

The aerospace industry uses far-reaching electronics technologies that pertain to the safety and functionality of aircrafts and spacecrafts. Therefore, it requires sophisticated devices that can withstand environmental extremes that would render standard PCBs inoperable. Such extremes include radical changes in temperature, harmful chemicals, and intense vibrations. That is why it is important to work with a specialized PCB assembly supplier that has the experience and expertise needed for high-grade electronic systems in this demanding industry.

When you’re looking for a partner that can offer you top-quality printed circuit assembly for your next project, the first step is to make sure that they are certified as an ISO 9001:2015 manufacturer. This means that they will have an integrated quality management system in place to ensure that all of the components and processes involved in manufacturing the PCBs are up to standards and adhere to best practices. This also guarantees that your final product will be functional and durable.

In addition to making sure that all components meet IPC specifications, your supplier should also use proper component placement procedures. This involves ensuring that the leads are properly placed, and that the board is free from any voids or other issues that could compromise its integrity. The assembler should also test the components to ensure that they are working correctly. This is a crucial part of the process because any mistakes can negatively impact the final product.

For example, it is vital to use the right type of solder. In particular, you’ll want to use a halogen-free solder because this is less toxic and won’t cause any harm to the environment. Additionally, it will help prevent corrosion and other damage to the board.

Lastly, your supplier should always perform inspections throughout the entire manufacturing process to identify any potential issues and catch any defects that may occur. These inspections should cover a variety of different aspects, including the physical appearance of the board, the continuity and polarity of the connections, the soldering quality, and more. The assembler should also conduct thorough inspections after the boards have been soldered to make sure that they meet all of the appropriate specifications.

In addition to using proper assembly techniques, you’ll want to choose a supplier that offers a wide range of options for the types of components used in your circuit board. This includes a broad selection of both through-hole and surface-mounted components, as well as flex and rigid-flex boards. The latter are particularly useful in the aerospace industry because they are more adaptable to tight spaces, and they provide a good balance between strength and weight.

Finally, your supplier should be able to offer a number of different finishing options. For instance, they should be able to apply acrylic sprays that protect the finished product from moisture. In addition, they should be able to offer a number different layers that allow the circuit boards to disperse heat more efficiently.
