What is PCB in aerospace?
PCBs used in aerospace are not your standard circuit boards. They must function reliably in mission-critical applications. Whether in satellites or fighter jets, these boards operate under vibration, shock, radiation, and severe thermal cycles.
These boards connect complex systems like navigation, communication, radar, and control systems. They’re usually made with high-Tg materials, low-loss laminates, and precise impedance control. Aerospace PCBs often go through rigorous quality testing, including thermal cycling, X-ray inspection, and even real-time functional testing.
In short, aerospace PCBs are the backbone of modern flight technology—so choosing the right manufacturer is essential.
Aerospace PCB Design Standards
To serve the aerospace market, PCB design must follow specific standards. These guidelines make sure that the board will function consistently under stress.
Some common standards include:
- IPC-6012DS: This defines the quality and reliability levels for rigid PCBs used in space and military systems.
- AS9100D: A quality standard tailored for aerospace manufacturers.
- MIL-PRF-31032: U.S. military standards for printed circuit boards.
Besides compliance, top aerospace PCB manufacturers invest in robust design reviews. This step ensures all aspects—material, stack-up, impedance, trace widths—match the application’s requirement before going into production.

Who is HDI PCB Manufacturer?
An HDI PCB manufacturer specializes in high-density interconnect technology. In essence, these boards provide more functionality within a smaller footprint. This becomes especially valuable in aerospace applications, where space and weight are tightly restricted. As a result, choosing a reliable HDI PCB manufacturer is critical for aerospace projects where performance, size, and durability all play a vital role. When it comes to proven expertise, manufacturers like Best Technology, Sanmina, and Unimicron lead the way with precision manufacturing and full compliance with aerospace standards.
HDI boards feature:
- Micro vias and blind/buried vias
- High layer counts
- Tight line and space width
- Controlled impedance routing
In aerospace systems, HDI PCBs are widely used in sensors, communication systems, and satellite controls. Therefore, choosing the right HDI PCB manufacturer is essential to ensure reliability through high-quality materials, fine-pitch components, and proper EMI shielding—all of which are critical in flight-sensitive equipment.
At Best Technology, we are recognized for our high-precision fabrication and strong reliability in demanding sectors, especially aerospace. Furthermore, our HDI PCB manufacturing capabilities include stacked and staggered micro vias, laser-drilled vias, and support for 2 to 16-layer PCB designs. In addition to that, Best Technology offers HDI PCB prototyping as well as small-batch and high-volume production to meet various customer needs. As a trusted partner, we proudly support several aerospace OEMs with consistent quality and dependable service.
Aerospace PCB Manufacturers in USA
Aerospace PCB manufacturers in the USA are known for strict quality processes and strong compliance.
