The Sintered Silver Frontier

Mastering High-Temperature Interconnects for Next-Generation Power Electronics

The silicon limit has been shattered, but can your packaging survive the heat?

Strategic Objectives

• Master the metallurgy of silver sintering to achieve superior thermal conductivity.

• Navigate the transition from liquid-phase soldering to solid-state diffusion.

• Implement pressure and pressure-less processing techniques for maximum reliability.

• Analyze failure mechanisms to ensure long-term stability in extreme environments.

The Core Challenge

Traditional solders fail at the 200°C threshold, creating a massive bottleneck for Wide Bandgap semiconductors and high-density power modules.
