Gold Paste
Gold-tin solder paste is used in a variety of high-reliability applications, where its high melting point, non-creep, high-tensile stress, thermal and electrical conductivity, as well as proven usage life makes it a standard "known-good" material.

Indalloy® 182
Indalloy® 182 (80Au/20Sn) has a melting point of 280°C (556°F). It can be made into solder paste form with various options to address specific applications. Gold-tin solder paste is generally used in applications that require a high melting temperature (over 150°C), good thermal fatigue properties, and high-temperature strength. It is also used in applications that require a high tensile strength and high corrosive resistance, or in step soldering applications where the paste will not melt during a subsequent low-temperature reflow process. For these reasons, Indalloy® 182 solder paste is widely used in military, aerospace, high-power LED, and medical applications
