PCBs Be Used in Aerospace Applications
The electronics used in planes, space shuttles, and satellites require PCBs that can tolerate environmental conditions that would quickly render standard circuit boards inoperative. They must be able to withstand temperature extremes, harmful chemicals, intense vibrations and mechanical abuse. They must also be capable of withstanding radiation exposure. This type of specialized electronic design can be complex, but it can be highly rewarding to those who successfully complete the challenge.
Compared to those designed for consumer electronics, aerospace PCBs require a greater number of layers. This helps them transfer electricity more efficiently, reducing the likelihood of overheating or electrical overload. In addition, these devices are generally built with more space between components, which can prevent damage from excessive contact or static charge.
Aerospace-grade electronic pcb board are typically referred to as mil-spec and have a tighter tolerance than those found in commercial grade products, with tolerances ranging from one to two percent. Similarly, there is a strict separation requirement between parts that generate high and low frequencies. Inadequate separation can produce interference and noise, which can significantly degrade signal quality.

Can PCBs Be Used in Aerospace Applications?
While there are many ways to manufacture a PCB, the most crucial factor for those who wish to use them in aerospace applications is that they comply with rigorous industry standards and certifications. These are non-negotiable and must be incorporated into the manufacturing process at every step, from raw materials to finished product. This ensures that every aspect of the final device meets the industry’s highest standards.
The FAA and EASA place a heavy emphasis on safety, which requires PCBs to pass rigorous testing to demonstrate their ability to withstand harsh environments and maintain structural integrity. In order to pass these tests, manufacturers must adhere to the FAA and EASA’s stringent quality and documentation requirements.
Whether they’re in the cockpit of a jet plane or aboard a space shuttle, electronic components that fail to meet these rigorous standards could threaten human life. For instance, a defective autopilot system in an airplane could cause an accident and possibly lead to fatal consequences. The good news is that companies like EEI Manufacturing know how to design and fabricate a PCB that’s ready to take on the challenges of the aerospace industry.
To help them meet the industry’s highest standards, these companies must employ a thorough quality management system that includes documenting every step of the manufacturing and assembly process. This provides a clear audit trail and enables the company to track potential issues throughout each stage of the production cycle. It also ensures that the final product is free from defects that could compromise its effectiveness and reliability in an aerospace application. The end result is a PCB that can withstand the harsh conditions of aerospace applications for years to come. Interested in learning more? Contact us today for a quote!
