Hi Folks!

Does anyone have any copper plating test results that they can share?
Specifically we are seeking to understand the range of physical properties
that are being seen. Tensile and elongation are of course the most common
attributes measured but we have interest in what other tests are commonly
employed and what values are common.(e.g. fatigue ductility, [ high and low
cycle], bulge testing etc.) Also there is interest in hardness and grain
structure. I will gladly summarize the information submitted back to all. I
am providing a form here that could serve as a template for the data.(If you
have additional information you would like to see please feel free to add
it)  Thanks for considering this request and thanks in advance for you help.

Cheers!
J. Fjelstad
