Abstract:
1. An apparatus for making a plurality of multilayer circuitized substrates, said apparatus comprising: a device for continuously feeding a first conductive layer having first and second opposing surfaces; a device for forming holes within said first conductive layer which extend through the thickness of said first conductive layer; a device for creating a dielectric layer of said circuitized substrates by depositing photo-imageable dielectric material on said first and second opposing surfaces of said first conductive layer and within said holes extending through said thickness of said first conductive layer; a device for forming first and second patterns within said photo-imageable dielectric material on said opposing surfaces of said first conductive layer, respectively, each of said patterns including openings therein which align with said holes within said first conductive layer; a device for providing electrically conductive material within said openings and on selected parts of the external surfaces of said photo-imageable material on said first and second opposing surfaces of said first conductive layer, respectively, to render said openings electrically conductive and to form circuit patterns on said selected parts of said surfaces of said photo-imageable material; and a segmenting device for segmenting said first conductive layer, said dielectric layer comprising said photo-imageable material on said opposing surfaces of said first conductive layer, and said circuit patterns on said photo-imageable material to define a plurality of circuitized substrates each having a pattern of conductive thru-holes therein, all of said steps being performed while said first conductive layer is in the form of a continuous, solid member.
