Gold-Germanium Alloy Solder Ribbon/Sheet Advantages

• Low Soldering Temperature: Melting point is 356°C, with soldering temperatures between 380-400°C.
• Good Wettability & Corrosion Resistance: Excellent flowability and minimal erosion of gold plating, with 88 wt% Au content for low diffusion in thin coatings.
• High Tensile Strength: Room temperature tensile strength of around 220MPa, comparable to high-temperature solders, achieved at lower temperatures.
• Low Coefficient of Thermal Expansion (CTE): Lower CTE than AuSn and AuSi, ensuring better compatibility with silicon in electronic packaging.
• Good Thermal Conductivity: Provides mechanical support and heat dissipation for semiconductor chips in microelectronic devices.
• Low Vapor Pressure: Ensures stability in high-vacuum applications.
• Superior Corrosion & Oxidation Resistance: Better performance than silver-based alloys.
• Good Flowability: Ideal for precise soldering applications.
• Good High-Temperature Stability: High soldering strength with minimal brittle phase formation during soldering.
