Aluminum Nitride Ceramic AMB Copper-clad Substrate
Puwei's Aluminum Nitride Ceramic AMB Copper-clad Substrate represents the forefront of thermal management for extreme power electronics. Engineered using Active Metal Brazing (AMB) technology, it bonds high-purity AlN ceramic with oxygen-free copper to create a superior platform for advanced Electronic Packaging.
Core Advantages
Extreme Thermal Conductivity: 170-200 W/m·K, 5-10x higher than Al₂O₃.
Unmatched Bond Strength: >70 MPa peel strength ensures reliability in harsh conditions.
Superior Thermal Cycling: Withstands over 5,000 cycles (-55°C to 150°C).
Optimized CTE Match: Closely matches silicon and SiC, reducing stress in high-power microelectronic components.
