Hi Anand,
ENIG is Electroless Nickel Immersion Gold Plating & is not suitable for
Gold Wire Bonding as the thickness of Gold is only 3-8microinches & for
gold wire bonding you would need at least 30-40microinches. Soft Gold
Plating is an electroplating process which can be plated to the required
thickness without any issue, of course at a cost. However if you want to
use ENIG, then some of the Chemistry vendors provide what is called a
Nickel-Palladium-Gold where the bonding is to the Palladium & the gold
is very thin like the ENIG process. But this is suitable for Aluminium
Wire bonding,. Hope this helps. If you need more info pls feel free to
contact me......
Thanks & Best Regards,
