Hello Folks,
Got a big project done and goes into fab now. A surprise just popped up where the turn-key fab house said they can't get boards tin-lead plated and nickel-plated anymore. So we are going with gold immersion since some areas are mechanically contacted and thus can't have HASL. The rest could be HASL but that makes it complicated and black-pad isn't really an issue these days anymore.
Did nickel-plating become totally outlawed by now? How about Canada and other countries?
