Our products have been successfully applied in diagnostic devices of global medical brands, serving medical institutions in over 40 countries and regions.

　　Core Technical Advantages: Engineered for Diagnostic Device Requirements

　　1. Medical-Grade Material Selection & Environmental Adaptability

　　We strictly select medical-grade materials that meet ISO 13485 and biocompatibility (where applicable) standards to adapt to the complex working environments of diagnostic equipment: ① Base material: High-Tg (≥170℃) FR-4, PTFE, or high-frequency substrates (for imaging devices), featuring excellent dimensional stability, high-temperature resistance (adapting to equipment continuous operation), and low dielectric loss (ensuring signal integrity); ② Conductive material: Oxygen-free copper (OFHC) with high purity (≥99.99%), ensuring low signal attenuation and stable electrical conductivity for high-precision signal transmission; ③ Solder mask: Medical-grade solder mask ink (compliant with USP Class VI), with good chemical resistance (resisting cleaning agents and reagents used in diagnostic processes) and insulation performance; ④ Adhesive: High-temperature resistant and low-outgassing adhesive, ensuring reliable bonding of PCB layers and avoiding interference with diagnostic test results. All materials undergo rigorous environmental adaptability testing (temperature, humidity, chemical corrosion) to meet the long-term stable operation requirements of diagnostic equipment.

　　2. High-Precision Signal Acquisition & Data Processing Design

　　Aiming at the high-precision signal acquisition and rapid data processing requirements of diagnostic devices, our R&D team optimizes circuit design: ① High-precision analog signal circuit design: Adopt low-noise amplifier (LNA) layout, separate analog and digital signal regions, and add grounding shielding layers to minimize signal interference, ensuring accurate acquisition of weak biological signals (such as blood glucose, electrolyte, and imaging signals); ② High-speed digital signal processing: Use high-density interconnect (HDI) technology (line width/line spacing ≤2mil/2mil) and high-speed signal transmission lines (such as HDMI, LVDS), supporting data transmission rates up to 10Gbps for rapid processing of massive diagnostic data; ③ Multi-module compatibility design: Reserve standardized interfaces (USB, PCIe, Ethernet) and expandable circuits, enabling seamless integration with sensors, detectors, display modules, and data storage units of diagnostic equipment; ④ Power supply stability design: Adopt multi-channel isolated power supply circuits, ensuring stable voltage output for different functional modules and avoiding power fluctuation-induced diagnostic errors.

　　3. Reliable Manufacturing Process & Quality Consistency

　　We adopt advanced and reliable manufacturing processes to ensure the quality consistency and operational stability of diagnostic device PCBs: ① HDI precision manufacturing: Use laser drilling, plasma desmear, and electroplating technologies to achieve high-precision interconnection, ensuring the accuracy of high-density circuits; ② Controlled impedance manufacturing: Strictly control the dielectric constant of substrates and copper layer thickness, ensuring impedance consistency (tolerance ±3%) for high-speed signal transmission; ③ Automated assembly process: Adopt SMT (Surface Mount Technology) automated assembly lines, ensuring precise placement of components and reducing manual operation errors; ④ Post-manufacturing reliability treatment: Conduct high-temperature aging (125℃, 500h) and thermal shock tests to eliminate residual stress of the PCB, ensuring stable performance under temperature fluctuations in medical environments. The entire manufacturing process is fully traceable, with complete process records for each batch of PCBs.

　　4. Electromagnetic Compatibility (EMC) & Anti-Interference Enhancement

　　Diagnostic equipment often operates in complex electromagnetic environments (with multiple medical devices working simultaneously), requiring PCBs to have excellent anti-interference capabilities: ① EMC optimization design: Adopt reasonable component layout, signal line routing, and grounding strategies to reduce electromagnetic radiation and improve anti-interference performance, complying with IEC 60601-1-2 EMC standards for medical devices; ② Shielding design: Add metal shielding layers or shielding covers for key signal modules (such as analog signal acquisition units), isolating external electromagnetic interference; ③ Filtering design: Integrate high-performance filters in power supply and signal circuits to suppress noise and ensure the purity of input and output signals. These designs ensure that the PCB can maintain stable operation without interfering with other medical equipment or being interfered by them.

　　Strict Quality Control System: Compliance & Diagnostic Accuracy Assurance

　　We establish a strict full-process quality control system compliant with ISO 13485 and FDA QSR 820, covering material incoming, design, manufacturing, testing, and delivery. Advanced testing equipment and rigorous inspection procedures ensure each diagnostic device PCB meets the highest quality standards and supports accurate diagnosis. Key quality control links include:

　　Raw Material Inspection: Inspect the chemical composition, physical properties, and electrical performance of medical-grade materials using spectrum analyzers, universal testing machines, and impedance analyzers. Only materials with complete qualification certificates and passing all tests are allowed to enter production, with full traceability of material batches.

　　Design Verification: Conduct EMC simulation and signal integrity analysis to verify the anti-interference capability and data transmission stability of the PCB; use finite element analysis (FEA) to test mechanical strength and dimensional stability; perform functional simulation to ensure the PCB meets the specific diagnostic function requirements. All design verification data are documented and archived.

　　Manufacturing Process Monitoring: Monitor key manufacturing parameters (temperature, pressure, time) in real time using high-precision sensors; conduct in-process inspection of PCB dimensions, line width/line spacing, and component placement accuracy using automated optical inspection (AOI) equipment (detection accuracy ±1μm) and X-ray inspection equipment. Implement Statistical Process Control (SPC) to ensure process stability and product consistency.

　　Finished Product Comprehensive Testing: Conduct a series of strict tests on finished PCBs: ① Electrical performance testing (continuity, insulation resistance, impedance, high-speed signal transmission, functional module compatibility); ② Environmental reliability testing (high-temperature aging, humidity aging, thermal shock, vibration test—simulating medical environment use); ③ EMC testing (radiated emission, electrostatic discharge, surge immunity) complying with IEC 60601-1-2; ④ Visual inspection (no defects such as scratches, bubbles, or solder mask peeling). Implement 100% inspection for key functional PCBs and AQL 0.65 sampling inspection for general PCBs, with unqualified products strictly rejected.

　　Quality Documentation: Provide customers with complete quality documentation packages, including material certificates, design verification reports, manufacturing process records, finished product test reports (especially EMC and signal integrity test data), and ISO 13485 certification documents. All documents comply with FDA audit requirements, ensuring full traceability of product quality.
