Abstract
The present invention provides a partially completed wiring circuit board assembly sheet capable of preventing deposition of a plating metal on the surface of a metal sheet, even when pinholes are produced in an insulating layer for insulating a lead wire for electroplating from a metal sheet. The assembly sheetof the present invention has a metal sheet, multiple wiring circuit board forming areaA in compartments on the metal sheet and areaB for forming a lead wire for electroplating, which is in compartment on the metal sheet. Each areaA has a partially completed wiring circuit board. The partially completed wiring circuit boardis equipped with a base insulating layer, a wiring patternand a cover insulating layer. In the areaB, a first insulating layer, a lead wirefor electroplating and a second insulating layerare laminated in this order. Of the metal sheet, an openingis formed in the part under the lead wire
