You don't TS bond gold wire to nickel [of ENIG] for the same reason that you don't TS bond gold wire to hard gold. [Nickel or maybe cobalt is used to harden soft gold.] Together nickel and gold produce unreliable bonds. Look here: * http://www.smta.

I would like to know if ENIG is widely used for the thermosonic gold wire bonding or this application is an exotic one. And I also wold like to talk to someone who uses printed circuits with ENIG finish for such an application. I do not quite underst

Wire bonding a die to a package has traditionally been performed using either aluminum or gold wire. Gold wire provides the ability to use a ball and stitch process. This technique provides more control over loop height and bond placement. The drawback has been the increasing cost of the gold wire. Lower cost Al wire has been used for wedge-wedge bonds but these are not as versatile for complex package assembly. The use of copper wire for ball-stitch bonding has been proposed and recently implemented in high volume to solve the cost issues with gold. As one would expect, bonding with copper is not as forgiving as with gold mainly due to oxide growth and hardness differences. This paper will examine the common failure mechanisms that one might experience when implementing this new technology.

As a surface finish for PCBs, Electroless Nickel/Electroless Palladium/Immersion Gold (ENEPIG) was selected over Electroless Nickel/Immersion Gold (ENIG) for CMOS image sensor applications with both surface mount technology (SMT) and gold ball bonding processes in mind based on the research available on-line. Challenges in the wire bonding process on ENEPIG with regards to bondability and other plating related issues are summarized.
