[mems-talk] Bonding gold wires to gold electrode

[Yue Mun Pun, Jeffrey]

Hi,
I need to bond gold wires to gold electrode.  Typically, how thick should the gold electrode be and what should the surface area of the electrode be for a good bond?  
Also, will there be any impact if the gold electrode is sitting on a film of SU-8, for if ultrasound is used in the bonding process, I'm afraid that the underlying SU-8 might crack due to the high energy of the ultrasound.
