Patent ID: 7329817

Claim:
A partially completed wiring circuit board assembly sheet equipped with the following (A) to (C); (A) a metal sheet, (B) multiple wiring circuit board forming areas in compartments on the metal sheet, each of which comprises a partially completed wiring circuit board comprising a base insulating layer, a wiring pattern and a cover insulating layer laminated in this order, and an opening for forming a terminal at a given part of the cover insulating layer, and (C) an area for forming a lead wire for electroplating, which is in a compartment in the metal sheet, which comprises a first insulating layer, a lead wire for electroplating and a second insulating layer laminated in this order, wherein the first insulating layer is formed by the same process as for the base insulating layer, the lead wire for electroplating has multiple through holes, is formed by the same process as for the wiring pattern, and is connected to multiple wiring patterns on the multiple wiring circuit board forming areas (B) so as to provide a power to the multiple wiring patterns, and a part thereof is exposed to form a power feeding part, the second insulating layer is formed by the same process as for the cover insulating layer, and wherein an opening is formed on the metal sheet (A) beneath the lead wire for electroplating.
