Mr Gentex,
why do you ask? Thought Au wirebonding on IAg wasn't different from other Ag plating, provided that the thickness is enough and that the whole system responds correctly to U/S waves. Some say, that one needs higher than usual temperature for long time reliability bonds, se A2.2.2 Essex University:
http://privatewww.essex.ac.uk/~bolat/Wirebonding.html
the above is quite a lesson for many! Or a mini dictionary for wirebonders..
Will be interesting to see the answers.
