We have an application which is asking for a ENIG finish with Ni spec of 2-4 um and Au of 0.05-0.1um.
 
What is the industry expectation of NI specification for Aluminium wirebonding? I think 2-4 is a little on the low side, and am worried about possible Nickel corrosion and poor bonding adhesion, especially if the Nickel is towards the lower side of the 2-4um.
