Hi all, I'm looking for a way to reduce the gold diffusion into a tin based solder (except the use of the expensive Au/Sn solder). Is there alloys that have this effect? Or can it be reached by the contamination of gold by some metals (like Pt, Pd, Cd,...)? I know the gold embrittlement phenomenon and this is not an issue here but well the "consumption of gold by the solder".
