J STD Revision "F" now states: (note that the new wording/changes are highlighted below) Gold Removal. Gold removal is performed to reduce the risk of failure associated with embrittled solder. Gold embrittlement is not a visually inspectable anomaly. In cases where analysis has determined there is a gold embrittlement condition.
