Hi Phil,
I tried that link at the time and it didn't work so I trashed it. Maybe
there was
a problem with our Intranet at the time. Do you still have that link?
Tim and Ingemar,
We are not using embedded/buried capacitors. The capacitance we wish to
achieve is
on external layers using copper pads. We succeed with the rogers non-UL
material.
Now we need to replicate the results with a UL material. We are looking to
create
a capacitance of 0.25pF and these are used in sampling 3.5kV of RF. We do not
know precisely what didn't work with the UL Rogers material and why the non-UL
did work. At this stage we are just trying different materials and looking
at end results for our application, of which I am unable to describe in detail.
