High-performance packaging substrate material with micron-scale gold-tin (AuSn) solder layers pre-deposited onto metallized aluminum nitride (AlN) ceramic plates. With excellent thermal management features and highly reliable die-attach performance, they are widely used in applications such as high-power diode lasers and optical communication modules, enabling higher device stability, longer system lifetime, and more scalable process.
With its outstanding advantages, the AlN-based substrates are becoming a key enabling technology for next-generation high-performance optical communication modules, when the demands on thermal performance and reliability in optical communications and advanced packaging continue to grow.
