Patent ID: 6996903

Claim:
A method for forming at least one multisegmented plated through hole (PTH) in a substrate, comprising the steps of: providing a first laminate having a dielectric layer and a second laminate having a dielectric layer; forming a first selective plate core (SPC) by sandwiching a dielectric layer between a first metal layer and a second metal layer such that the dielectric layer of the first SPC includes a platable dielectric material, forming a hole through the first SPC, and filling the hole with a nonplatable dielectric material to form a plug within the hole; forming the substrate by sandwiching the first SPC between the first laminate and the second laminate; forming a first through hole through the substrate such that the first through hole passes through the plug resulting in a cylindrical segment of the nonplatable dielectric material circumscribing a portion of the first through hole; and metalizing a wall of the first through hole to form a first PTH of the at least one PTH, resulting in a metal plating on the first PTH that: plates to the first laminate, plates to the second laminate, does not plate to the first SPC, and is not continuous from the first laminate to the second laminate.
