MULTILAYER WIRING PLATE AND METHOD FOR FABRICATING SAME

摘要

A multilayer wiring plate includes a coaxial wire includes a signal line, an insulation coating and an outer peripheral conductor. An insulating layer is arranged on an inner or outer layer side. A metal film circuit is arranged by the intermediary of the insulating layer, and the metal film circuit and the outer peripheral conductor and signal line of the coaxial wire are connected. A signal line connection part that connects the signal line to the metal film circuit includes a penetration hole A that passes through the insulating layer and the outer peripheral conductor; the coaxial wire from which the outer peripheral conductor is removed inside the penetration hole A; a hole filling resin filled inside the penetration hole A; a penetration hole B that passes through the hole filling resin and the signal line; and a plated layer arranged on an inner wall of the penetration hole B.

1. A multilayer wiring plate, wherein a coaxial wire including a signal line, an insulation coating around the signal line, and an outer peripheral conductor arranged on the insulation coating, is arranged in an inner layer, an insulating layer is arranged on an inner layer side or an outer layer side with respect to the coaxial wire, a metal film circuit formed by circuit-processing metal foil or a plated layer is arranged by the intermediary of the insulating layer, and the metal film circuit and the outer peripheral conductor and signal line of the coaxial wire are connected,
wherein a signal line connection part that connects the signal line of the coaxial wire to the metal film circuit, includes: a penetration hole A that passes through the insulating layer and the outer peripheral conductor of the coaxial wire; the coaxial wire arranged inside the penetration hole A in a state in which the outer peripheral conductor is removed and the coaxial wire includes the signal line; a hole filling resin filled inside the penetration hole A; a penetration hole B that passes through the hole filling resin and the signal line of the coaxial wire; and a plated layer arranged on an inner wall of the penetration hole B.
