    Abstract: A wiring board of the present invention readily controls a power source voltage and unwanted irradiation noises developed across a power source layer and a ground layer over a broad range of frequencies with a simple arrangement. The wiring board has an on-board surface on the surface of a dielectric substrate, on which a semiconductor device or the like is mounted, and a power source layer and a ground layer, which are made of a conductor material principally composed of at least one kind of element selected from Cu, W, and Mo, are provided on the back surface of the dielectric substrate or within the same. The periphery of at least one of low resistance areas of the power source layer and ground layer, respectively is provided with a corresponding high resistance area having a higher sheet resistance than that of the respective low resistance areas.

    Abstract: Disclosed is a solder alloy in use for bonding electric or electronic parts, containing: 3 to 12% by weight of a zin component; and a tin component. The oxygen content of the solder alloy is reduced to 100 ppm or less. Using the solder alloy, a bonding portion is formed on the substrate and the electronic part is mounted thereon to obtain a substrate for mounting the electronic part and a substrate on which the electronic part is mounted. The bonding portion made of the above solder alloy can prevent migration.

    Abstract: A method for fabricating a microstrip resonator line permitting precise control of line width, edge definition and thickness. On a substrate, there is printed a first conductive layer having a precisely controlled width. This first layer has a thickness less than the desired thickness of the resonator line. Further conductive layers are printed over the first layer to build up to the desired thickness of the resonator line based on skin depth requirement at the frequency of operation. Each of the further conductive layers for building the thickness of the line has a width less than that of the first conductive layer so that resonator line width is controlled by the width of the first layer.

    Abstract: A circuit board structure includes a substrate, a third dielectric layer, a fourth dielectric layer, a first external circuit layer, a second external circuit layer, a conductive through hole electrically connected to the first and second external circuit layers, a first annular retaining wall surrounding the conductive through hole, and a second annular retaining wall surrounding the conductive through hole. The first annular retaining wall is electrically connected to the first external circuit layer and a first inner circuit layer. The second annular retaining wall is electrically connected to the second external circuit layer and a second inner circuit layer. A first ground circuit, the first annular retaining wall, and the first inner circuit layer define a first ground path surrounding a first signal circuit. A second ground circuit, the second annular retaining wall, and the second inner circuit layer define a second ground path surrounding a second signal circuit.
