Introduction:


The gold-tin eutectic solder (AuSn20) has a melting temperature of 280°C. It has been widely used in aerospace, medical and other fields with high reliability due to excellent thermal and electrical conductivity, high corrosion resistance and good mechanical properties. The gold-tin eutectic alloy can be made into solder paste to meet various application requirements. The solder joints formed with gold-tin solder paste are generally used in applications that require a high operating temperature (over 150°C), good thermal fatigue properties, high strength and good capacity of resisting corrosion and oxidation.

It is also used in step soldering applications where the paste will not melt during a subsequent low-temperature reflow process. In comparison with gold-tin solder preforms, gold-tin solder paste shows an apparent advantage in convenience, which makes it suitable for high reliability packaging of micro photoelectric devices and high thermal conductivity packaging of high power devices.
