　　We strictly select medical-grade materials with excellent energy-saving performance and compliance to lay the foundation for low power consumption: ① Base material: High-Tg (≥170℃) low-loss FR-4 or ceramic substrates with low dielectric constant (Dk ≤3.8), reducing signal transmission loss and unnecessary energy consumption; ② Conductive material: High-purity oxygen-free copper (OFHC ≥99.99%) with optimized copper thickness (12-35μm), ensuring low resistance and reducing current transmission energy loss; ③ Solder mask & Adhesive: Medical-grade low-outgassing, high-insulation solder mask ink and adhesives (compliant with USP Class VI), avoiding leakage current and ensuring energy efficiency; ④ Passive component matching: Cooperate with ISO-certified suppliers to select ultra-low-power resistors, capacitors, and inductors, minimizing standby energy consumption of passive components. All materials undergo rigorous incoming inspection to ensure compliance with medical standards and energy-saving performance requirements.

　　2. Advanced Low-Power Circuit Design Optimization

　　Our R&D team adopts multi-dimensional low-power design strategies tailored to medical device scenarios: ① Power management optimization: Integrate high-efficiency DC-DC converters and LDO regulators with low quiescent current (Iq ≤1μA) to improve power conversion efficiency (up to 95%+), reducing energy loss during power conversion; ② Dynamic power control: Design multi-level power management circuits that automatically switch between high-performance and low-power modes based on device working status (e.g., standby, detection, data transmission), minimizing unnecessary energy consumption; ③ Analog-digital circuit isolation: Separate analog and digital signal regions with independent power supplies, optimizing the working voltage of each module (e.g., 1.8V for digital circuits, 3.3V for analog circuits) to avoid overvoltage energy waste; ④ High-integration layout: Adopt HDI technology (line width/line spacing ≤2mil/2mil) to realize high-density circuit integration, reducing the number of components and shortening signal paths, thereby reducing overall energy consumption; ⑤ Signal integrity optimization: Optimize impedance matching (tolerance ±3%) and reduce signal reflection, ensuring stable signal transmission with minimal energy loss. All low-power designs undergo strict simulation and verification to ensure compatibility with medical device functional requirements.

　　3. Precision Manufacturing Process for Energy Efficiency Enhancement

　　We adopt precision manufacturing processes to ensure the low-power performance of PCBs is fully realized: ① Controlled impedance manufacturing: Strictly control the dielectric constant of substrates and copper layer thickness uniformity, ensuring stable signal transmission and avoiding energy loss caused by impedance mismatch; ② Fine-pitch assembly technology: Use SMT automated assembly lines with high positioning accuracy (±0.03mm) to mount ultra-small, low-power components, ensuring reliable soldering and reducing contact resistance; ③ Thermal management optimization: Optimize PCB layout and heat dissipation paths to avoid local overheating, which can lead to increased power consumption and component failure; ④ Cleanroom production: Adopt Class 10000 cleanroom facilities to avoid contamination of PCB surfaces, which can cause leakage current and increase standby power consumption; ⑤ Full-process traceability: Assign unique batch numbers to each PCB, with complete records of materials, manufacturing steps, and testing data, ensuring the traceability of low-power performance-related parameters. All manufacturing equipment is regularly calibrated to maintain process stability and energy efficiency consistency.

　　4. Multi-Dimensional Reliability & Low-Power Synergy

　　While ensuring low power consumption, we comprehensively enhance PCB reliability to adapt to harsh medical environments: ① Surface treatment: Adopt electroless nickel immersion gold (ENIG) with controlled thickness (nickel 5-10μm, gold 0.05-0.1μm), ensuring low contact resistance and excellent corrosion resistance, avoiding increased power consumption due to surface oxidation; ② Aging & stability testing: Conduct high-temperature aging (125℃, 500h) and low-temperature storage tests (-40℃, 500h) to eliminate residual stress, ensuring stable low-power performance under extreme temperature conditions; ③ Leakage current control: Optimize solder mask coverage and edge sealing processes, reducing leakage current to ≤1nA, ensuring minimal standby energy consumption; ④ Anti-interference enhancement: Integrate EMC optimization design (compliant with IEC 60601-1-2) and filtering circuits, avoiding energy waste caused by electromagnetic interference-induced abnormal power consumption. All reliability enhancement measures are validated to ensure synergy with low-power performance.

　　Strict Quality Control System for Low-Power & Medical Reliability

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

　　Raw Material Inspection: Inspect medical-grade materials for dielectric constant, resistance, insulation performance, and low-power compatibility using spectrum analyzers, impedance analyzers, and leakage current testers. Only materials with complete certification documents and passing low-power performance-related tests are approved for production, with full batch traceability.

　　Design Verification & Validation: Conduct low-power simulation (static and dynamic power consumption analysis) to verify energy-saving performance; perform signal integrity analysis to ensure stable signal transmission under low-voltage conditions; carry out functional validation under different power modes to confirm the PCB meets medical device working requirements. All low-power design parameters are documented and archived.

　　In-Process Inspection: Use automated optical inspection (AOI, detection accuracy ±1μm) and X-ray inspection equipment to inspect PCB dimensions, line width/line spacing, and component placement accuracy. Monitor key manufacturing parameters (temperature, pressure, soldering time) in real time to ensure low contact resistance and stable power conversion performance. Implement Statistical Process Control (SPC) to ensure process stability.

　　Finished Product Comprehensive Testing: Conduct rigorous testing on all finished low-power medical PCBs, with a focus on energy-saving performance: ① Low-power performance testing (standby power consumption ≤5μW, working power consumption optimization verification, power conversion efficiency testing); ② Electrical performance testing (continuity, insulation resistance, leakage current, impedance, signal transmission); ③ Environmental reliability testing (high-temperature/low-temperature operation, humidity aging, thermal shock—verifying low-power stability under extreme conditions); ④ EMC testing (radiated emission, electrostatic discharge) compliant with IEC 60601-1-2; ⑤ Biocompatibility testing (for implantable PCBs) compliant with ISO 10993; ⑥ Visual inspection (no defects such as scratches, bubbles, or solder mask peeling). 100% inspection is implemented for life-critical low-power PCBs, with AQL 0.65 sampling inspection for general medical PCBs—unqualified products are strictly rejected.
