    摘要: A method for fabricating a component board which includes forming a first main-face-side Au plating layer on surfaces of main-face-side connection terminals and a first back-face-side Au plating layer on surfaces of back-face-side connection terminals of the component board; covering the first main-face-side Au plating layer with a protection layer; forming a second back-face-side Au plating layer on the first back-face-side Au plating layer; and removing the protection layer after completing the second Au plating step. Alternatively, the first back-face-side Au plating layer may be removed after completing the masking step. Displacement Au plating is used as the first and second Au plating.

    摘要: A printed-wiring substrate 1 has main-face-side connection terminals 33 for solder-bonding to connection terminals 83 of an IC chip 81 on a main face 1A thereof and back-face-side connection terminals 41 for connecting, through mechanical contact, to connection terminals 93 of a motherboard 91 on a back face 1B thereof. The surface of each of the main-face-side connection terminals 33 is covered with a main-face-side displacement Au plating layer 45 having a thickness of 0.03 to 0.12 &mgr;m, and the surface of each of the back-face-side connection terminals 41 is covered with a back-face-side displacement Au plating layer 55, which is thicker than the main-face-side displacement Au plating layer 45 and has a thickness of 0.2 &mgr;m or greater.

    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.
