Abstract

AuSn20 solder is widely used in the areas of high reliability microelectronic devices and optoelectronic devices packaging due to its excellent comprehensive properties.However

the coarse as-cast microstructure and inhomogeneous distribution of primary phase can result in the brittleness of the AuSn20 alloy

so it is difficult to prepare.Research of the preparation technology for the AuSn20 solder has been one of current hotspots.The principle and characteristics to prepare AuSn20 alloy solder using solid forming technology

liquid forming technology

thin-films technology and rapid solidification technology were reviewed

and the development direction of the preparation technology for the AuSn20 solder were also pointed out.
