This invention discloses a brain-computer interface implantable medical connector and its fabrication method, belonging to the field of biomedical engineering. The connector comprises a multi-channel alumina ceramic substrate, a pure titanium ring frame, and pure gold solder. The sides of the ceramic substrate are fully coated with a tungsten metallization layer and electroplated with nickel-gold. An annular groove is formed in the inner ring of the pure titanium ring frame to accommodate the solder. The ceramic substrate with multiple tungsten paste-filled through-holes is fabricated using the HTCC process. Vacuum brazing is then used to weld the sides of the ceramic substrate to the titanium ring frame, forming a fully circumferentially airtight structure. This invention uses all medical-grade materials, exhibiting excellent biocompatibility. The unique side metallization and ring frame groove design significantly improves welding reliability and airtightness, with a leakage rate ≤1×10⁻⁶. ‑10 Pa·m 3 / s; High-purity alumina ceramic and the isolation channel design ensure high insulation, with an insulation resistance ≥1×10⁻⁶ between adjacent channels. 12 Ω. This invention solves the technical problems of insufficient airtightness, easy signal crosstalk, and poor biocompatibility of existing implantable connectors.
