Wiring board and method for manufacturing the same |
摘要 |
A wiring board has a laminated structure having a recessed portion on a first-surface side of the laminated structure and a solder resist layer on a second-surface side of the laminated structure on the opposite side of the first-surface side. The laminated structure has a first-surface side pad formed in the bottom of the recessed portion and a second-surface side pad formed on the second-surface side of the laminated structure, the solder resist layer has a first opening portion and a second opening portion formed in the solder resist layer, the first opening portion is exposing the second-surface side pad, the second opening portion is formed on a back face of the recessed portion, and the back face of the recessed portion does not include the second-surface side pad. |
