Printed wiring board and method for manufacturing printed wiring board

摘要

A printed wiring board and a method for manufacturing the same are provided. The printed wiring board includes a resin insulation layer having a first surface and a second surface opposite the first surface, and includes an opening for a first via conductor. An electronic-component mounting pad is formed on the first surface of the resin insulation layer. The electronic-component mounting pad includes a portion embedded in the resin insulation layer and a portion protruding from the resin insulation layer. The protruding portion covers the embedded portion and a portion of the first surface of the resin insulation layer that surrounds the embedded portion. A first conductive circuit is formed on the second surface of the resin insulation layer. A first via conductor is formed in the opening of the resin insulation layer and connects the electronic-component mounting pad and the first conductive circuit.
