Thanks

Subject: [TN] Rough Gold causing plating shorts

I need a favor in regard to rough gold (ENIG) causing plating shorts.  I 
need a brief synopsis of which process or processes typically go out of 
balance to cause this issue.
Basis: My supplier is indicating electrical shorts attributable to rough 
gold being the reason for their low lot yields on a rigid flex. 
Unfortunately, I know enough to be dangerous but not necessarily effective 
in this realm.
