Anybody out there experiencing mass dewetting issues from North American board shops?
 
From what I understand primary causes for dewetting (assuming the reflow/wave profile is bang on) is all on the board, ie nickel corrosion, degeneration of the nickel, or outgassing of the nickel/copper.  (I'm talking enig here.)
 
Anybody?
