Has anybody done characterization on existing BGA packages recently? I need to
know if there is anyone who can do this for me and what is the estimated cost. The
required measurements include characteristic impedance along traces, delay and
gain on both directions of traces across the frequency band of 500M - 2GHz, ground
bounce, cross talking, and ringing. I would like to obtain a data range for all
these to see if some particular BGA packages are suitable for my applications.
Ideally I would like to add some equivalent to bond wire and IC input capacitance
during test. Your help is greatly appreciated.
