Especially since the Sn96 starts out with 4% noble metal.

Subject: Re: [TN] Soldering using Sn96
Happy Friday Jim! This is only a guess but one possible reason for such
a recommendation is the potential to have solder joint integrity
degradation due to gold embrittlement. A high tin content solder alloy
and gold surface finishes do not necessarily mean a gold embrittlement
situation but it would be on aspect of a solder process that would need
to be kept in mind.

Technetters:
I happened to come across a solder chart from the Indium Corporation and
noticed that they do not recommend using Sn96 solder on gold-plated
surfaces. Can anyone elaborate on this?
