　　We strictly select biocompatible materials certified by ISO 10993 to lay the foundation for human safety: ① Base material: Biocompatible polyimide (PI), ceramic (Al₂O₃), or medical-grade FR-4 (compliant with ISO 10993-1), ensuring no harmful substance release and excellent tissue compatibility; ② Conductive material: High-purity oxygen-free copper (OFHC ≥99.99%) with biocompatible surface passivation, avoiding metal ion leaching that could cause tissue irritation; ③ Solder mask & Adhesive: Biocompatible solder mask ink (USP Class VI certified) and medical-grade epoxy adhesives (compliant with ISO 10993-4), ensuring no cytotoxicity, sensitization, or irritation, and resisting degradation in human body fluids (for implantable devices); ④ Surface treatment: Adopt biocompatible electroless nickel immersion gold (ENIG, compliant with ISO 10993-10) or titanium nitride (TiN) plating, enhancing biocompatibility and corrosion resistance in human environments. All materials undergo rigorous biocompatibility testing (cytotoxicity, sensitization, irritation, hemocompatibility) and are traceable to their original certificates.

　　2. Biocompatibility-Optimized Structural & Circuit Design

　　Our R&D team adopts targeted design strategies to enhance biocompatibility and human adaptability: ① Smooth surface design: Optimize PCB edge rounding and surface polishing, avoiding sharp edges that could damage human tissue or skin; ② Sealing & encapsulation design: For implantable or moisture-exposed devices (e.g., wearable monitors), adopt biocompatible encapsulation materials (e.g., Parylene C, compliant with ISO 10993) to prevent material degradation and harmful substance release, and resist body fluid or sweat corrosion; ③ Miniaturized & lightweight design: For implantable and wearable devices, optimize layout to reduce PCB size and weight, minimizing tissue damage (for implants) and improving wearing comfort (for wearable devices); ④ Low-power design: Match biocompatible design with low-power circuits, reducing heat generation to avoid thermal irritation to human tissue; ⑤ Biosecure circuit isolation: Isolate signal and power circuits to avoid electrical interference that could affect human physiological functions. All designs undergo biocompatibility simulation and human-environment adaptation testing to ensure safety and comfort.

　　3. Biosecure Manufacturing Process for Contamination Control

　　We adopt strict biosecure manufacturing processes to avoid contamination and ensure biocompatibility: ① High-grade cleanroom production: Conduct manufacturing in Class 1000 (ISO 7) cleanroom facilities (Class 100 for implantable PCBs), controlling particulate matter, microorganisms, and volatile organic compounds (VOCs) to prevent contamination; ② Contamination-free processing: Use biocompatible process aids (e.g., cleaning agents compliant with USP Class VI) and avoid harmful substances (lead, mercury, phthalates) throughout the production process; ③ Precision assembly: Adopt high-precision SMT assembly equipment (positioning accuracy ±0.03mm) with biosecure fixtures, ensuring no mechanical damage to biocompatible materials and reliable component mounting; ④ Strict process control: Monitor key manufacturing parameters (cleanroom cleanliness, temperature, humidity, processing time) in real time, implementing Statistical Process Control (SPC) to ensure process stability and biocompatibility consistency; ⑤ Full-process traceability: Assign unique batch numbers to each PCB, with complete records of materials, manufacturing steps, cleanroom monitoring data, and biocompatibility test results, ensuring full traceability of product safety.

　　4. Multi-Dimensional Biocompatibility & Long-Term Stability Enhancement

　　We implement comprehensive measures to enhance biocompatibility and long-term stability in human-contact scenarios: ① Post-manufacturing cleaning & degassing: Conduct multi-stage cleaning (ultrasonic cleaning with biocompatible agents) and vacuum degassing to remove residual process contaminants and VOCs; ② Accelerated aging testing: Simulate long-term human environment (body temperature 37℃, body fluid immersion) for 1000+ hours to verify material stability and no harmful substance release; ③ Corrosion resistance enhancement: For implantable PCBs, adopt specialized surface treatment and encapsulation to resist corrosion from body fluids (blood, lymph, interstitial fluid) and avoid material degradation; ④ Sterilization compatibility: Ensure compatibility with mainstream medical sterilization methods (autoclave, EtO, gamma radiation) without affecting biocompatibility after sterilization. All enhancement measures are validated through rigorous biocompatibility and long-term stability testing to meet the safety requirements of human-contact medical devices.

　　Strict Quality Control System for Biocompatibility & Medical Safety

　　We operate a comprehensive quality control system fully aligned with ISO 13485, FDA QSR 820, and ISO 10993, with specialized testing items for biocompatibility. Advanced biocompatibility testing equipment and rigorous inspection procedures ensure each biocompatible medical PCB meets both biocompatibility requirements and medical-grade safety standards. Key quality control links include:

　　Raw Material Biocompatibility Inspection: Inspect all incoming materials for biocompatibility certificates (ISO 10993, USP Class VI) and conduct sampling biocompatibility tests (cytotoxicity, sensitization) using professional biocompatibility labs. Only materials with complete certification and passing test results are approved for production, with full batch traceability.

　　Design Verification & Validation: Conduct biocompatibility simulation analysis to verify material and structural safety in human environments; perform human-contact adaptation testing (wear comfort, tissue compatibility simulation); carry out functional validation under simulated human conditions (37℃, body fluid immersion) to ensure the PCB meets medical device working requirements. All biocompatibility design parameters are documented and archived.

　　In-Process Biosecurity Inspection: Monitor cleanroom cleanliness (particulate matter, microorganisms) and process contamination in real time; use automated optical inspection (AOI, detection accuracy ±1μm) to inspect PCB surface defects and component mounting quality; conduct intermediate cleaning verification to ensure no residual contaminants. Implement strict process isolation to avoid cross-contamination between batches.

　　Finished Product Comprehensive Testing: Conduct rigorous testing on all finished biocompatible medical PCBs, with a focus on biocompatibility: ① Comprehensive biocompatibility testing (ISO 10993 series: cytotoxicity Class I, no sensitization, no irritation, hemocompatibility compliant); ② Residual contaminant testing (VOCs, heavy metals, process residues ≤0.1μg/g); ③ Long-term stability testing (simulated human environment immersion for 1000h, verifying no harmful substance release); ④ Sterilization compatibility testing (biocompatibility retention after target sterilization cycles); ⑤ Electrical performance testing (continuity, insulation resistance, signal transmission) under simulated human conditions; ⑥ Visual inspection (smooth surface, no defects, no contamination). 100% inspection is implemented for implantable PCBs, with AQL 0.25 sampling inspection for wearable PCBs—unqualified products are strictly rejected.
