Technical Depth: Why Metallization Matters
Metallized ceramic substrates serve as the critical bridge between the fragile semiconductor die and the robust external cooling system. The process involves bonding a metal layer (typically Copper, Silver, or Gold) onto a ceramic base. This provides:
- Superior Heat Dissipation: Thermal conductivity up to 230 W/mK for AlN.
- Electrical Isolation: High dielectric strength for high-voltage applications.
- Strong Adhesion: Peel strength exceeding 50N/cm through specialized Mo-Mn or Thick Film processes.
- Complex Circuitry: Ability to etch fine lines for high-frequency RF modules.
In the context of Industrial 4.0, Shanghai Creative Advanced Materials Co., Ltd is leading the way by optimizing the interaction between ceramic morphology and metallic interface bonding, ensuring zero-delamination even under -55°C to 150°C thermal shocks.
