摘要:
A multilayer wiring board assembly component comprises: an insulating substrate component (the insulating resin layer 111); a conductive layer 112 formed on one surface of said insulating substrate component 111 in the form of an electrode pattern; an adhesive layer 113 formed on the other surface of said insulating substrate component 111; and a conductive resin composition 115 with which is filled a through hole passing through said insulating substrate component 111, said adhesive layer and said conductive layer in order to make interlayer interconnection. The bore diameter of the conductive layer portion 114b of the through hole 114 is smaller than the bore diameter of the insulating resin layer portion and the adhesive layer portion 114a to establish electrical connection between the conductive resin composition 115 and the conductive layer 112 by the rare surface 112a of the conductive layer 112.

摘要:
A base material (20) is arranged on top of at least one first internal layer base material (10), and a second internal base material (30) is arranged underneath the base material (10). And thereafter a surface layer circuitry conductive foil (40) is arranged underneath the base material (30), and subsequently these materials are colaminated for forming a colaminated body (80). While this colaminating operation, conductive portions being formed in the base materials 10, 30 are aligned to electrically connect one another for forming an internal circuitry. And thereafter, an interlayer conductive portion (51) being electrically connected to the internal circuitry is formed, and a minute circuitry is formed on the top of the base material (20) and the conductive foil (40) accordingly.

摘要:
At least one base material having a wiring circuit that has been formed into a predetermined outer shape is bonded to a motherboard. The motherboard wiring board and the base material having a wiring circuit are electrically connected to each other at least one portion through an inner via hole. The outer shape of the base material having a wiring circuit is smaller than the outer shape of the motherboard, with the base material having a wiring circuit having an island shape on the motherboard.

摘要:
A multilayer wiring board assembly, a multilayer wiring board assembly component and a method of manufacture thereof are described in which it is possible to easily laminate together flexible FPCs having highly packing densities by via-on-via and chip-on-via. The multilayer wiring board assembly is laminated by laminating together a plurality of multilayer wiring board assembly components, each of which is made by preparing a copper plated resin film 10 made of a copper plated resin film made of a resin film having adhesivity which is provided with a copper foil bonded to one surface thereof and in which a through hole is opened through said copper foil and said resin film, and a conductive paste filler embedded by screen printing in the through hole of said copper plated resin film from said copper foil with a leading end of said conductive paste filler being projected from said resin film.
