I usually lurk on these pages as I am a rank newbie. I have been
helped a great deal from the experience and found here.
Here is my question. Computer circuit board is made from a substrate
material onto which copper has been fused, the circuitry pattern is
then etched in and the process goes on. I am looking for a source of
the basic substrate material, it can be cut to various shapes. My
instructor uses it for the roller printing process. It works
beautifully in assisting the transfer of the pattern as well as
protecting the rollers if using steel screen or sandpaper or any
material that may be potentially damaging to the mill. It also
survives the process for ad infinitum reuse. Anyone have an idea
where we can obtain a reliable source of this substrate material?
Thanks again for such a great forum for learning.
