Hi Brett-
You can purchase the C/I/C cores from a TI (Texas Instruments) located
in Attleboro MA. Unfortunately I don't have a phone number, but if you
have access to the web, you can get the number from www.switchboard.com,
or from www.altavista.digital.com, to name a few.
TI manufactures the cores, but only plate to 1 and 2 oz thick. I'm sure
you can get a plate shop to increase the thickness per you specific
requirement, probably even TI. Unfortunately, I'm hearing that they may
soon stop manufacturing the cores, so please, if anyone knows of another
source lemmkno!
Regarding the insulating filler material. Try "Howefill". This
material is manufactured by Arlon, located in California. Again, sorry
but I don't have a number (see above for phone search). I don't have
the numbers, 'cause we're not using these materials, as it's not needed
in our computer systems. However, the cross sectioning I've done for
one of our customers', using these materials - fun stuff!!
Good luck.

Technetters,
We need to obtain Cu-Inv-Cu .040" with 6 oz Cu on both sides.
Can anybody tell us where we can find this material?
We also are in need of the insulating filler for the Cu-Inv-Cu core
