1. Material System: High-purity alumina (Al₂O₃ ≥96%) – white, biocompatible, chemically inert, and cost-effective; or
aluminum nitride (AlN ≥96%) – gray, offering ultra-high thermal conductivity up to 170 W/(m·K) for efficient thermoelectric
conversion and high-power medical electronics.
2. Biocompatibility & Sterilization: Materials meet ISO 10993 biological evaluation standards (cytotoxicity, sensitization,
irritation) – suitable for implantable devices and long-term patient-contact equipment. Zero water absorption; withstands
repeated autoclave sterilization (121°C steam), EtO gas, and gamma irradiation – no warping, moisture uptake, or degradation.
3. Thermoelectric Efficiency: High thermal conductivity (Al₂O₃ ≥20 W/(m·K), AlN ≥170 W/(m·K)) enables rapid heat transfer
across thermoelectric modules (TEG/TEC), maximizing temperature differential (ΔT) and power generation efficiency.
Low thermal expansion mismatch ensures reliable solder joints under repeated thermal cycling.
4. Electrical Safety & Insulation: Volume resistivity ≥10¹³ Ω·cm; dielectric strength >15 kV/mm; fully compliant with IEC 60601
requirements – ensuring patient and operator safety in bio-medical devices.
1. Implantable Medical Devices – Pacemakers, neurostimulators, and cochlear implants rely on hermetic ceramic substrates
with decades-long reliability. Alumina provides inert, non-toxic, biocompatible performance for long-term implantation.
2. Thermoelectric Generation (TEG) Modules – Wearable body-heat harvesters, industrial waste-heat recovery systems,
and radioisotope thermoelectric generators use ceramic PCBs as support substrates for thermoelectric conversion, requiring
high thermal conductivity and electrical insulation.
3. Medical Diagnostic Instruments – Ultrasound transducers, X-ray detectors, PCR thermal cyclers, and biosensors leverage
ceramic PCBs for superior thermal management, high-frequency signal integrity, and chemical resistance.
4. Thermoelectric Cooling (TEC) Devices – Medical laser systems, clinical diagnostic equipment, and laboratory scientific
instruments utilize ceramic-based TEC modules for precise temperature control with compact geometry and silent solid-state operation.
Our ceramic PCB manufacturing facility is equipped with advanced production lines including:
l DPC (Direct Plated Copper) process for high-precision metallization
l Thick-film screen printing and co-firing furnaces (up to 1000°C)
l Laser cutting and precision drilling equipment
l Automatic optical inspection (AOI) and X-ray inspection systems
l ENIG (Electroless Nickel Immersion Gold) surface treatment line
l ISO 13485 certified quality management system
l Full material traceability from ceramic substrate lot to finished device
Quality is ensured through 100% electrical testing, thermal cycling tests, biocompatibility screening, and solderability tests in
compliance with IPC-TM-650, GB/T, ISO 10993, and IEC 60601-1 standards.
