Learn moreFAQ
What standards must military PCBs comply with?
Military-grade PCBs typically meet IPC Class 3 or higher for high-reliability electronics, MIL-PRF-31032 for performance, MIL-STD-810 for environmental conditions, MIL-STD-461 for EMI/EMC compliance, and ITAR for export control. Aerospace projects may also require AS9100D certification.
What materials are best for defense & military PCB manufacturing?
High-Tg FR-4, polyimide, PTFE, and hybrid laminates are common for RF/microwave systems. Heavy copper (up to 12oz) is often used in power distribution. Selection depends on operating temperature range, EMI performance, and mechanical durability.
How do you ensure PCBs can withstand extreme military environments?
We perform rigorous testing including thermal cycling (-55°C to +200°C), high-vibration endurance, mechanical shock, salt fog corrosion, humidity exposure, and EMI/EMC compliance. All tests simulate battlefield and aerospace conditions.
Can you manufacture PCBs for radar, EW, avionics, and missile guidance systems?
Yes. We produce high-frequency PTFE and hybrid boards for radar and EW, secure high-speed digital PCBs for avionics, and ultra-rugged power boards for missile and armored systems.
What are the main cost drivers in defense & military PCB & PCBA production?
Key factors include specialized materials, layer count, copper weight, controlled impedance, conformal coating, and compliance with MIL-STD environmental testing. Advanced builds with blind/buried vias, heavy copper, or RF performance tuning also influence cost.
