Indium-Based Alloy Preformed Solder Sheet

Indium-Based Alloy Preformed Solder Sheets are available in various compositions, such as In100, In97Ag3, In66Sn34, In52Sn48, and In50Sn50. These alloys are known for their outstanding ductility, malleability, and ultra-low temperature sealing capabilities. Due to indium's low melting point, these alloys can form low-melting eutectic solder materials when combined with elements like Sn, Pb, and Ag. Indium-based solders offer high corrosion resistance in alkaline environments and excellent wettability on metals and non-metals. The resulting solder joints exhibit high plasticity and low electrical resistance, making them ideal for matching the thermal expansion of various materials, particularly ceramics and glass. These characteristics have made indium-based solder alloys essential in microelectronics packaging, especially for applications requiring reliable seals at low temperatures. Cleanliness of the indium is critical in sealing applications, as any remaining oxide layers can compromise the integrity of the seal and lead to leakage. Heeger Materials provides these preformed solder sheets with high purity and precision to meet diverse sealing and bonding needs.

Indium-Based Alloy Preformed Solder Sheet Selection Notes

Indium-Based Alloy Preformed Solder Sheet Advantages

• High Thermal Conductivity: The thermal conductivity is relatively high (86W/mK at 85°C).
• Good Ductility and Malleability: It deforms with moderate pressure to fill small gaps between mating parts.
• Low Melting Point: Some indium-based alloys have a melting point below 180°C, making them ideal for multiple soldering processes or low-temperature reflow soldering.
• Low Vapor Pressure: Suitable for high-vacuum soldering applications.
• Sealing Capability: Indium can seal channels or other uneven surfaces without requiring reflow, making it ideal for typical sealing operations.

Indium-Based Alloy Preformed Solder Sheet Applications

• Ultra-Low Temperature Sealing: Indium-based alloys retain their ductility and malleability even at temperatures below -150°C, making them ideal for ultra-low temperature sealing applications.
• Soldering or Fusion: With a melting point range from 5°C to 310°C, indium-based alloys are suitable for soldering or fusing components with varying temperature requirements.
• Cooling of High-End Components: These alloys can effectively lower the operating temperature of sensitive components by up to 10°C, enhancing the performance and longevity of high-end devices.
• Vacuum Sealing: Indium alloys provide a reliable seal in high-vacuum environments, making them essential in semiconductor, aerospace, and other vacuum-sensitive applications.
• Electronics Packaging: Indium-based alloys are used for packaging electronic components, offering excellent thermal and electrical conductivity, while also accommodating different thermal expansion rates between materials.
