STOEBELIGT dielectric composition method of forming a dielectric green tape (AEGREEN TAPEAE) thereof, and method of forming a multi-layer connecting portion (substrate for printed circuit boards) as the green tape

摘要

A casting composition for making dielectric green tapes comprising a dispersion of finely divided solids of (a) a noncrystallizable glass and (b) a mixture of refractory oxides in a solution of (c) organic polymer, which is readily depolymerizable at 825 DEG -1025 DEG C. in a nonoxidizing atmosphere, dissolved in (d) volatile nonaqueous solvent.
