Victor, I know exactly what you are referring to, but would ask that you
point to some published data that backs up that statement.
Kind regards,
John Burke

Bob, Lee,
Beware of the immersion silver plating layer thickness which may
cause micro voiding at the PWB side of the interface with LF.

Several large OEMs are using immersion silver and others OSPs. You may
want to get some samples of immersion silver made as well.

Subject: [TN] gold vs copper plating on pcb's
Good Afternoon all,
Our company will be switching over to lead free and we have received
sample pcb's from one of our vendors and one board has gold (ENIG) for
the traces and one has copper (OSP). From some of the emails I have seen
on Technet it appears that gold is what most of companies are going to
be using? Is this correct or is there some other materials we should be
looking into to use? Is the gold more reliable than the copper?
Any input would be greatly appreciated.
