Jason, Let me try to answer your question with any reference to "Black Pad". I don't like to use an appearance name to describe a failure mode. The short answer to the question can a brittle interface fracture be present if using NiPdAu is YES. Regards, George George M.

I have a question - Can the Black Pad Defect be present if using NiPdAu? Can the palladium prevent black pad?
