Abstract

A method for producing small pitch z-axis electrical interconnections in layers of dielectric materials which are applied to printed wiring boards and diverse electronic packages. A method for parallel fabrication of intermediate structures which are subsequently jointed to form a final structure. In addition there is provided a z-interconnected electrical structure, employing dielectric materials such as resin coated copper, employable in the manufacture of diverse type of electronic packages, including printed wiring boards (PWBs), substrates, multi-chip modules and the like.
