Abstract:
1. A method of manufacturing a multilayer wiring board, comprising the steps of: fabricating a first wiring board including an insulating base member, wiring layers formed in desired shapes on both sides of the insulating base member, a conductive post formed on the wiring layer on one surface of the insulating base member, and a first stopper layer formed at a desired position around the conductive post, the first stopper layer having such a predetermined shape as may suppress in-plane misalignment that can possibly occur on the occasion of stacking; fabricating a second wiring board including an insulating base member, wiring layers formed in desired shapes on both sides of the insulating base member, a through hole for insertion of the conductive post therethrough, a connection terminal formed on the wiring layer on one surface of the insulating base member, and a second stopper layer that engages the first stopper layer and functions to suppress the in-plane misalignment on the occasion of the stacking; fabricating a third wiring board including an insulating base member, wiring layers formed in desired shapes on both sides of the insulating base member, and a connection terminal formed on the wiring layer on one surface of the insulating base member; stacking up the first, second and third wiring boards, the respective wiring boards being aligned with one another so that the wiring layers thereof are interconnected via the conductive post and the connection terminals, to thereby provide electrical connections through the wiring boards; and filling resin into a gap between adjacent two of the stacked wiring boards.
