I assume PCB soldering. Leaded or unleaded? there is a significant
difference

Subject: [TN] silver solders and thermal fatigue resistance

Greetings,

Can anyone provide a simple description of or provide/recommend articles
regarding the role of silver addition in solders?  I've seen reference in
several articles that it was originally used as a means to mitigate
migration of silver when soldering to thick silver deposits.  I've also seen
reference that it also increases the thermal fatigue resistance.  The latter
is what I am most interested in, and would like to better understand the
"why's".

Thanks,
Kevin Glidden
