    Abstract: A method of manufacturing a wiring board includes: forming an outer through hole in a core substrate; filling the outer through hole with an insulation resin; forming a first conductive layer on a surface of the insulation resin at a portion where a core connecting via is formed; forming a land around the first conductive layer; laminating the wiring layer on the core substrate after the forming of the first conductive layer and the forming of the land; forming an inner through hole having a smaller diameter than that of the outer through hole and penetrating through the core substrate and the wiring layer so as to penetrate through the insulation resin; and coating a first conductive film on an inner wall surface of the inner through hole, in which the core substrate and the first conductive film are electrically connected through the first conductive layer and the land.

    Abstract: One disclosed embodiment comprises formation of a padless via in a substrate. The padless via includes a hole through a metal layer blanketing the substrate, as well as the underlying substrate. An inner wall of the padless via hole receives a seed layer of a conductive material. Electrolytic differential plating is then performed, resulting in a preferential accumulation of a conductive plating material on the via inner wall, relative to that deposited on a surface of the substrate. In one embodiment, the differential plating is performed by addition of an organic suppressant to a plating bath.

    Abstract: A method for making a multilayer circuit board from circuit board layers, each including a dielectric layer and conductive traces thereon including a first metal. The method includes forming a through-via in a first circuit board layer, plating the through-via with the first metal, and coating a second metal onto the first metal of the first circuit board layer, the plated through-via, and the first metal. The method also includes aligning the first and second circuit board layers together so that the plated through-via of the first circuit board layer is adjacent a feature on the second circuit board layer, and heating and pressing the aligned first and second circuit board layers so as to laminate the dielectric layers together and form an intermetallic compound of the first and second metals bonding adjacent metal portions.
