Grant The solution to soldering problems with immersion gold boards is: find a supplier that can control his/her process. Electroplated gold over nickel is a very reasonable process. Billions of wire bound boards use it evry year.

Dave, Excellent information thank you. What I cant seem to establish is how other manufacturers have found the FLASH gold in terms of reliability especially considering that the flash process is more difficult to control.
