摘要： A printed-wiring substrate 1 includes internal dielectric resin layers 12 and 14. A main-surface-side external dielectric resin layer 13 is formed on the internal dielectric resin layer 12 such that the surface thereof serves as a substrate main-surface 1A. A back-surface-side external dielectric resin layer 15 is formed on the internal dielectric resin layer 14 such that the surface thereof serves as a substrate back-surface 1B. A surface 12A of the main-surface-side internal dielectric resin layer 12 and a surface 14A of the back-surface-side internal dielectric resin layer 14 are roughened. The substrate main-surface 1A and the substrate back-surface 1B are roughened such that surface roughness thereof is lower than that of the surfaces 12A and 14A.

摘要： An electronic device comprised of a wiring board with a semiconductor component. The device is unlikely to have any defects, such as cracks to a solder joint portion during a reflow process of a flip-chip connection. The semiconductor component is flip-chip bonded at a pad array at a component side thereof to a pad array at a board side by way of an individual solder joint portion. In a solder resist layer at a semiconductor component side and a solder resist layer at a board side, D/D0 is prepared to be in a range of 0.70 to 0.99, where D is a bottom inner diameter of an opening at the board side and D0 is a bottom inner diameter of an opening at the component side.

摘要： A method of producing a wiring board includes a preliminary plating step of forming a solder resist layer such that the main layer of each metal pad of the board is exposed in each corresponding opening and covering the surface of the exposed main layer with a preliminary Sn plated layer. A solder paste application step involves applying a solder paste, containing solder powder comprised of the high temperature Sn solder and thicker than the preliminary Sn plated layer, on the preliminary Sn plated layer. A subsequent solder melting step involves forming the Sn solder covering layer by melting the solder paste layer together with the preliminary Sn plated layer by heating the solder paste layer to a temperature higher than the liquid phase line temperature of the high temperature Sn solder. This wettingly extends the melted layers over the surface of the main layer.
