This question has come up again.  What are the adverse affects of gold 
plated terminations on SMT components?
     We have been seeing a number of new sample components with gold 
terminations, and to date, have disqualified  them based on gold 
embrittlement. .  Many of the vendors reps say that this issue is new to 
them and that they sell these parts all over with no questions/problems.  Is 
this still an issue?  If so, why are these vendors supplying parts, 
especially taped/reeled parts, with gold on them?  Tinning these would be 
expensive and hardly practical.
     Is there a spec/study/whatever that shows the maximum deposition of 
gold before it becomes a problem?
