Apparatus for making circuitized substrates using a continuous roll format in which layers of conductor and dielectric are fed into the apparatus, bonded, and passed on to other nearby work stations in which various processes such as hole formation, circuitization and, finally, segmentation occur. The resulting substrates can then be individually bonded to other, like substrates to form a larger multi-layered substrate with a plurality of conductive thru-holes, conductive and dielectric layers as part thereof.
