Automotive PCB & PCBA
What standards must automotive PCBs comply with?
Automotive-grade PCBs typically meet IPC-A-600 Class 3 for high-reliability electronics, IATF 16949 for quality management, and AEC-Q200/AEC-Q100 for component qualification. Compliance with ISO 26262 functional safety is also essential for safety-critical systems.
What materials are best for automotive PCB manufacturing?
High-Tg FR-4, polyimide, aluminum substrates, and metal core PCBs are common choices. Selection depends on the application’s thermal load, vibration resistance, and mechanical durability requirements.
How do you ensure PCBs can withstand automotive environments?
We perform rigorous reliability testing, including thermal cycling (-40°C to +150°C), vibration and shock tests, salt spray corrosion tests, and high-humidity endurance. These simulate real-world driving conditions to ensure long-term performance.
Can you manufacture PCBs for EV battery management systems (BMS) and ADAS?
Yes. We produce high-voltage, high-current boards for EV BMS, and high-frequency RF/microwave boards for ADAS radar and camera modules—meeting strict impedance control and EMI shielding requirements.
What are the main cost drivers in automotive PCB & PCBA production?
Key factors include material type, layer count, copper weight, manufacturing tolerances, functional safety certification, and reliability testing. Advanced features like blind/buried vias and heavy copper can also affect cost.
Do you provide both PCB fabrication and PCBA assembly for automotive projects?
Yes. We offer one-stop solutions from PCB manufacturing to full assembly, including component sourcing, functional testing, and conformal coating—streamlining supply chains for automotive OEMs and Tier 1 suppliers.
