Gold-Tin eutectic solder will be a staple diet, or a staple material, that's used in a lot of different applications from RF to LED and other higher temperature applications for the foreseeable future. What we're seeing though, is trends with Gallium Nitrites, Silicon Carbide, semiconductor devices coming along. Higher junction temperatures and the need for step soldering, where the Gold-Tin eutectic would be used as a second attached solder, after the initial die-attach.
