You definitely want to look at MVP. They have an excellent AOI made specifically for wirebond and hybrid AOI.

Our MVPs have been great. We really like their machine and support.

Ioan,
I've not dealt with these particular folks.
The short version response is that you will get what you pay for!
There can be SO many possible defect modes, especially if you have a mix of fine/heavy wire wedge + ball bonding. Exponentially add to that mix if you have RF/high frequency demands such as tight loop control, tight wire length control, tight bond size control, etc. in the mix.
Definitely, make up many 'salted' units for the systems to inspect.
Minimum/nominal/maximum conditions for each defect mode that you intend to consider. This gets VERY burdensome, but you need some metric [golden units] to judge the various machines by.
You may even end up going into each wire, or wire group, depending on bonder, and altering the looping profile to so you can determine if the AOI equipment can detect if the wire near the second bond is lying too close to an adjacent conductor, etc.
Tails on wedge bonds, and wire sweep/proximity to adjacent wires is usually the easy stuff
I don't have any current pricing usage info that would be meaningful, but will acknowledge that processing speeds and vision software has greatly improved so even if the machine will not do a COMPLETE inspection, possibly it can inspect for the most critical items, thereby taking some of the load of human inspectors which tend miss things....
FWIW

Subject: [TN] Wire-bonding AOI
Dear Technos,
I need info regarding AOI machines with wire bonding inspection capability.
Efficiency of the technology, suppliers, price tags, table top vs. inline, personal experiences, can they also do regular SMT AOI, anything you can tell me, on-line or off-line.
Any particular experience with this one?
