Method of forming multilayer ceramic substrates from large area green sheets.

摘要

A method is disclosed for forming multilayer ceramic substrates from large area ceramic green sheets (10), each having an array of layer sites (11) thereon, by serially aligning each individual layer site with respect to a die cavity (48) and punching the aligned layer site into the die cavity to thereby stack the requisite number of aligned layer sites. Individual layer site alignment ensures that each layer site is aligned with respect to the die cavity so that the dimensional tolerances between layer sites on the large area green sheet are eliminated. Thus, as large a green sheet as is cost effective may be employed, notwithstanding the fact that dimensional distortions on the large area green sheet would preclude alignment of corresponding layer site vias on superimposed large area green sheets.
