What materials are suitable for medical devices requiring autoclave sterilization?

High-Tg FR4 above 170°C, medical-grade polyimide and special PTFE laminates are adopted, which maintain stable electrical performance after multiple high-temperature autoclave cycles without degradation.Do you support fast-turn medical PCB prototypes for clinical R&D verification?

What compliance documents can you provide for medical FDA/CE registration?

We provide complete batch traceability documents, including raw material COA certificates, solder mask & substrate material qualification reports, AOI/X-Ray inspection logs, cleanroom production records, IPC standard test reports, RoHS and REACH compliance certificates. All files meet FDA and CE medical device audit and registration standards.

Do you offer medical PCB prototyping and small-batch clinical production?

Yes. We support rapid medical PCB prototyping and low-to-medium volume clinical production with consistent IPC Class 2/Class 3 quality, matching medical R&D iteration and trial launch demands.

What surface finishes are recommended for long-term medical device reliability?

Hard gold and immersion silver are preferred for medical PCBs, featuring excellent oxidation resistance, sterilization tolerance and stable conductivity. OSP and thin ENIG are only suitable for general non-sterile monitoring medical devices.

What Are Medical-Grade PCBs?

Medical-grade PCBs are ultra-reliable circuit boards built to strict healthcare compliance standards, eliminating trace-level failure risks for diagnostic, therapeutic and wearable medical devices. All boards follow strict design rules to deliver stable long-term operation in clinical environments.

Continuous Stable Operation: Optimized multi-layer layouts support 24/7 running under strict physiological & electrical loads.
Sterilization Compatible Materials: Specially selected substrates resist repeated high-temperature disinfection cycles.
