Puwei's 99.6% high-purity Alumina (Al2O3) Ceramic Substrate delivers exceptional thermal management, electrical insulation, and mechanical strength for the most demanding Power Devices and high-reliability electronic systems. Engineered as a superior Electronic Ceramic Product, it forms the critical foundation for power-intensive applications.
This substrate is engineered for performance and reliability across multiple high-power sectors:
Puwei maintains strict vertical integration and quality control:
All production follows ISO 9001 certified quality management systems, ensuring consistent performance and compliance with international standards.
We provide comprehensive OEM/ODM services to meet your exact needs:
Q: Why choose 99.6% Alumina over lower purity grades?
A: Higher purity delivers significantly better thermal conductivity, superior electrical insulation, enhanced mechanical strength, and improved chemical/thermal shock resistance—critical for high-reliability Power Devices.
Q: How does it compare to Aluminum Nitride (AlN)?
A: While Aluminum Nitride Ceramics offer higher thermal conductivity, 99.6% Alumina provides an excellent performance-to-cost balance for most high-power applications. Puwei supplies both and can recommend the optimal material.
Q: What metallization services are available?
A: We provide comprehensive Metallized Ceramics services including DBC and AMB, delivering fully processed substrates ready for component assembly and integration into final integrated circuit packages.
Puwei's 99.6% Alumina Ceramic Substrate combines material science excellence with precision manufacturing. It is the reliable, high-performance foundation that enhances system durability, manages heat efficiently, and supports innovation in next-generation power electronics across global industries.
