Aerospace & Aviation PCB & PCBA
What standards must aerospace PCBs comply with?
Aerospace-grade PCBs meet AS9100D, IPC Class 3, MIL-STD-810 (environmental), MIL-STD-461 (EMI/EMC), RTCA DO-160, NASA GEVS, and ITAR export control.
What materials are best suited for aerospace PCB manufacturing?
High-Tg polyimide, PTFE-based laminates (e.g. Rogers RT/duroid®), heavy copper layers, and low-outgassing substrates are preferred for durability and reliability.
How do you ensure PCBs withstand harsh aerospace environments?
Through rigorous HALT/HASS, thermal cycling (-55°C to +200°C), vibration, shock, salt fog, and humidity tests simulating flight and space conditions.
Can you manufacture PCBs for satellite communication and avionics?
Yes, we produce multi-layer HDI, rigid-flex, and RF/microwave PCBs compliant with aerospace specs and tight impedance controls.
What are the main cost drivers in aerospace PCB and PCBA production?
Key factors include advanced materials, layer counts, controlled impedance, functional safety certification, complex testing, and long lifecycle component sourcing.
Do you provide both PCB fabrication and PCBA assembly for aerospace projects?
Absolutely. We offer full turnkey solutions including design support, component sourcing, assembly, testing, conformal coating, and on-time delivery.
