Hi all,

Many shops have installed and are running Electrochemicals shadow process.
We have been running it over 6 years now. However, as hole sized get smaller
we are seeing more voids than usual. The actual cause of the voids is
somewhat of a debate at this time. The effect of not having a fixer module
on our shadow line seems to be primary focus at this time. Perhaps those of
you who are using shadow and are drilling .0135 holes would care to share
your experience along these lines. What is your opinion on a fixer module.
Is it necessary?  If we install one, do you think it will help reducing
voids in small holes.

The supplier highly recommends it but I never loose sight of the fact that
they are in business to sell equipment. So, without any intention of
slighting our suppliers suggestions ( who I find the majority of the time
correct is their recommendations) , I always inquire with folks actually
using the products before I decide to endorse spending any money that may
not be necessary.


All comments are appreciated.
