Product Process Specifications – Key Features for Medical Devices
1. Material System: High-purity alumina (Al₂O₃ ≥99.6%) – white, biocompatible and chemically inert; or aluminum nitride
(AlN ≥96%) – gray, offering ultra-high thermal conductivity up to 170 W/(m·K) for high-power medical electronics.
2. Biocompatibility Compliance: Materials meet ISO 10993 biological evaluation standards (cytotoxicity, sensitization,
irritation) – suitable for implantable devices and long-term patient-contact equipment.
3. Sterilization Resistance: Zero water absorption; withstands repeated autoclave sterilization (121°C steam), ethylene
oxide (EtO) gas, and gamma irradiation – no warping, moisture uptake, or degradation.
4. Electrical Safety & Insulation: Volume resistivity ≥10¹³ Ω·cm; fully compliant with IEC 60601 requirements for creepage,
clearance distances, and dielectric withstand voltage – ensuring patient and operator safety.
(Other standard parameters such as dielectric constant, flexural strength, and copper thickness are integrated into the
application descriptions below.)
Application Scenarios
1. Implantable Medical Devices – Pacemakers, cochlear implants, and neurostimulators rely on hermetic ceramic substrates
with decades-long reliability. Alumina provides inert, non toxic performance for long term implantation.
2. Diagnostic Imaging – Ultrasound transducer arrays, X ray detectors, and MRI gradient coil drivers use ceramic PCBs
for superior thermal management and high frequency signal integrity (low dielectric loss up to 20 MHz).
3. Surgical Instruments – Electrosurgical generators and laser scalpels utilize high power RF stages where ceramic PCBs
handle extreme thermal and voltage stresses, with high flexural strength (≥450 MPa) ensuring robustness under repeated
sterilization cycles.
4. Patient Monitoring & Lab Analysis – Precision sensor modules (temperature, pressure, biochemical) and DNA sequencers
leverage ceramic’s long-term dielectric stability, chemical resistance, and uniform heating performance.
