Jan, I take it you mean electrically non-conductive rather than thermally non-conductive? Filling holes in internal layers is often done with high-resin content pre-preg. What is your application that this is not a solution for you?

It has to be with a non-conductive material. Do any of you have recommendations of a hole filling material with this capability. Most of the material for ordinary innerlayer viaplugging has to low viscocity to provide a reliable fill. Any input will be welcome.
