Hi Gabriela, If you search the forum (couple years back) you'll find a string on the topic between Werner, Dave and I. The bottom line was - silver embrittlement doesn't exist.

The late Werner Engelmaier published an article: <http://www.globalsmt.net/smt/index.php?view=article&catid=42%3Acolumns-wern er-engelmaier&id=13358%3Asolder-joint-embrittlementits-not-just-gold&format= pdf&option=com_content&Itemid=65> http://www.globalsmt.net/smt/index.php?view=article&catid=42%3Acolumns-werne r-engelmaier&id=13358%3Asolder-joint-embrittlementits-not-just-gold&format=p df&option=com_content&Itemid=65 This article explains silver embrittelment as an addition to gold embrittelment in lead free solders used for soldering gold plated leads with SAC. Is there a correlation between my question and the article?
