First Article Inspection (FAI) for all new projects

Q10: Can you provide test reports and certificates?

A: Yes, we can provide First Article Inspection (FAI) reports, material certificates (COC), test reports, and compliance certificates (RoHS, REACH, UL, IATF 16949, ISO 13485, AS9100) upon request, to meet your industry regulatory requirements.

4. Industry-Specific FAQs

Q11: Do you offer automotive-grade PCBs?

A: Yes, we specialize in automotive PCB manufacturing, fully compliant with IATF 16949 quality management system and AEC-Q100 component standards.

Q12: Can you manufacture medical-grade PCBs?

A: Absolutely. Our medical PCBs are certified to ISO 13485, designed for life-support systems, diagnostic equipment, wearables, and medical imaging. We use biocompatible materials, implement strict traceability for all materials and processes, and provide full documentation for FDA/CE regulatory compliance.

Q13: What about aerospace-grade PCBs?

A: We produce aerospace PCBs compliant with AS9100 and IPC Class 3 standards, suitable for avionics, satellite, and defense applications. We offer high-reliability features such as controlled impedance, hermetic sealing, radiation-resistant materials, and full traceability, with rigorous environmental testing (high/low temperature, shock, vibration) to meet aerospace industry standards.

Q14: Do you support industrial control PCBs?

A: Yes, our industrial control PCBs are designed for harsh factory environments, with high-CTI, high-Tg, and thick copper options. We comply with IPC Class 3 standards, provide surge protection design support, and conduct EMC/EMI testing to ensure stable operation in industrial automation, power control, and IoT applications.
