Mirror Grade Double Sided Polished AlN Ceramic Substrate

Mirror Grade Double Sided Polished Aluminum Nitride (AlN) Ceramic Substrate Product Overview Puwei’s Mirror Grade Double Sided Polished AlN Ceramic Substrate sets the standard for thermal management and electrical integrity in advanced electronic packaging. Engineered with an ultra-smooth, optical-grade surface (Ra <0.02μm) and superior thermal conductivity (≥175 W/m·K), this substrate is the foundational component for high-reliability microelectronics, power devices, and high frequency module assemblies. It is specifically designed as a superior bare ceramic plate for use in the manufacturing of integrated circuits, thick film hybrid microcircuits, and other precision electronic systems where heat dissipation and surface flatness are critical. Performance comparison highlighting AlN's superior thermal conductivity. Core Features & Advantages Exceptional Thermal Management: With thermal conductivity 8-10 times higher than alumina, it effectively dissipates heat from high pow…
