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?
