[mems-talk] Wire bond pads *atop* SU-8

[Jon Fox]

I have reason to pattern a wire bond pad on the top of some SU-8 but am 
having trouble getting
sufficient adhesion with Ti and Cr to allow for ultrasonic ball bonds of 
sufficient strength.

What are other folks doing to make wire bonds to structures build atop 
an SU-8 layer?
