    Abstract: A printed wiring board having a through hole conductor formed on the surface of a through hole formed in a copper-clad laminate board, and on the surface of the copper-clad laminate board 1 in the vicinity of an opening of the through hole. The through hole conductor is filled with a positive photosensitive resin. A capped conductor is formed on the positive photosensitive resin and is coupled to the through hole conductor. Further, a circuit pattern is formed on the surface of the copper-clad laminate board. An insulating layer is formed on the surface of the copper-clad laminate board, capped conductor, and the circuit pattern, and formed with a via hole extending from the surface of the insulating layer to the capped conductor. A via conductor is formed inside the via hole and on the surface of the insulating layer in the vicinity of an opening of the via hole.

    Abstract: The present invention provides a number of techniques for laminating and interconnecting multiple substrates to form a multilayer package or other circuit component. A solder bump may be formed on the conductive pad of at least one of two or more substrates. The solder bump preferably is formed from an application of solder paste to the conductive pad(s). Adhesive films may be positioned between the surfaces of the substrates having the conductive pads, where the adhesive films include apertures located substantially over the conductive pads such that the conductive pads and/or solder bumps confront each other through the aperture. The two or more substrates then may be pressed together to mechanically bond the two or more substrates via the adhesive films. The solder bump(s) may be reflowed during or after the lamination to create a solder segment that provides an electrical connection between the conductive pads through the aperture in the adhesive films.

    Abstract: Closed vias are formed in a multilayer printed circuit board by laminating a dielectric layer to one side of a central core having a metal layer on each side. A second dielectric layer is laminated to the other side of the central core. Closed vias in the central core have been formed by drilling partially through but not completely penetrating the central core, and then completing the via from the opposite side with a hole that is much smaller in diameter to form a pathway that penetrates completely through the central core from one side to another. The via is then plated with metal to substantially close the smaller hole. Approximately one half of the closed vias are situated such that the closed aperture faces one dielectric layer and a remainder of the closed vias are situated such that the closed aperture faces the other dielectric layer. Resin from one dielectric layer fills the cavities of approximately one half of the closed vias, and resin from the other dielectric layer fills the circular cavities of the remainder of the closed vias. The total amount of resin migrated from each of the dielectric layers into the closed via cavities is approximately equal.
