Dear Readers,
I have to measure the variation in position between a fiducial on the
top surface of a substrate and a pad pattern on the bottom surface. I
don't have any inspection equipment that can view both surfaces
simultaneously and am dissatisfied with our current method of
measurement.
can anyone direct me to a UK facility that may be able to carry out such
a measurement for me?
Thanks,
--
