Aerospace PCB
STHL PCB has long specialized in aerospace-grade PCB solutions for mission-critical applications such as satellite communication modules, avionics systems, and flight control units. In the demanding environment of space and high-altitude aviation, PCBs must endure extreme temperature swings, intense vibration, radiation exposure, and humidity. STHL PCB selects aerospace-approved high-TG laminates or ceramic substrates and employs multi-layer high-density interconnect (HDI) processes to guarantee signal integrity and electromagnetic compatibility. Through precise impedance control and stack-up design, we optimize high-frequency RF paths and mixed-signal traces, minimizing crosstalk and EMI risk.
For thermal management, STHL PCB integrates thermal vias, copper pours, and heat-spreading layers in critical areas to efficiently dissipate heat from high-power or RF components. In more severe scenarios, thick copper and specialized heat-dissipating substrates further enhance thermal performance. Mechanical robustness is equally vital: reinforced board structures and plated-through hole enhancements, combined with conformal coatings or potting options, protect against moisture and contamination in high-altitude or space conditions. All boards are manufactured under IPC Class 3 workmanship standards, follow AS9100 quality processes, and undergo MIL-STD environmental testing for vibration, thermal cycling, humidity, and radiation tolerance. From prototyping to volume production, full traceability ensures consistency.
Our design team uses advanced CAD tools for signal integrity and thermal simulations before laying out multi-layer HDI structures. In fabrication, precise etching and lamination maintain tight tolerances and layer alignment. Assembly with aerospace-grade components follows SMT and through-hole processes, with rigorous AOI, X-ray, and flying probe inspections. Optional conformal coating or potting adds extra environmental protection. Long-term reliability testing—including thermal cycling, vibration shock, humidity, and radiation evaluations—validates PCB performance throughout launch, flight, and ground operations.
These engineering practices yield tangible results: in satellite communication modules, STHL PCBs sustain exceptional signal integrity; in avionics equipment, stable thermal performance and vibration resistance ensure long-term reliability; in flight control and navigation systems, boards proven under rigorous testing operate continuously without failure. Choosing STHL PCB’s aerospace-grade PCBs provides a solid electronic foundation for your projects: from proof-of-concept to prototyping and mass production, we deliver end-to-end support, ensuring every board functions reliably in the harshest environments and safeguards mission success.
