Products comply with relevant ROHS and REACH regulations, with certification code: GXLH41023Q10642R0S.
Puwei offers comprehensive OEM & ODM services to meet specific application requirements:
Higher purity (99.6% vs 96% or 90%) delivers significantly better thermal conductivity, superior electrical insulation, enhanced mechanical strength, and improved resistance to chemical corrosion and thermal shock - critical for high-reliability power applications.
While Aluminum Nitride Ceramics offer higher thermal conductivity, our 99.6% alumina provides an excellent balance of performance and cost-effectiveness for most high-power applications. We offer both materials and can recommend the optimal solution based on technical and budgetary requirements.
We provide comprehensive Metallized Ceramics services including Direct Bonded Copper (DBC) and Active Metal Brazed (AMB) processes, delivering fully processed substrates ready for component assembly and integration into Microelectronics Packaging systems.
We offer extensive customization including dimensional specifications, surface finishes, metallization patterns, and specialized material treatments to meet unique application requirements in Electronic Packaging and power electronics.
Puwei's 99.6% Alumina Substrate represents the convergence of material science excellence and precision manufacturing expertise. With robust production capabilities, comprehensive customization options, and rigorous quality control, we provide reliable thermal management solutions that enhance system performance, improve reliability, and reduce operational costs across renewable energy, electric vehicle, industrial automation, and advanced electronics sectors.
