[What is claimed:] [1.]a) forming at least one via having a predetermined diameter in a green sheet material having a low dielectric constant;b) filling said via with a selected metal paste and drying said sheet;c) selecting a second green sheet of a material having a high dielectric constant and forming at least one aperture therein, said aperture having a diameter equal to the desired diameter of said via surrounded by said material having a low dielectric constant; .d) placing said sheet of low dielectric constant material above said material having a high dielectric constant and aligning a center line of said via with a center line of said aperture; and punching through said sheet of low dielectric constant material with a punch equal to or less than the diameter of said aperture, said punch having a central axis aligned with a central axis of said via and said aperture to create a plug of low dielectric constant material containing said via inserted into said aperture in said high dielectric constant material.
