发明名称 Partially completed wiring circuit board assembly sheet and production method of wiring circuit board using said sheet
摘要 <p>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 sheet 100 of the present invention has a metal sheet 1, multiple wiring circuit board forming area 1A in compartments on the metal sheet and area 1B for forming a lead wire for electroplating, which is in compartment on the metal sheet 1. Each area 1A has a partially completed wiring circuit board 10. The partially completed wiring circuit board 10 is equipped with a base insulating layer 2, a wiring pattern 3 and a cover insulating layer 4. In the area 1B, a first insulating layer 12, a lead wire 13 for electroplating and a second insulating layer 14 are laminated in this order. Of the metal sheet 1, an opening 16 is formed in the part under the lead wire 13.</p>
