Abstract: A laminate capacitor circuit board which permits constants of various kinds of circuit elements to be set by selectively effected connections between wiring layers, and a laminate capacitor circuit board which permits distributed circuit constants in a high-frequency wiring layer sandwiched between two shielding wiring layers to be set as desired. These circuits are formed with at least a pattern of a conductive foil on each dielectric layer, and include a plurality of wiring layers laminated one upon another, a wiring layer for connections laminated to a surface of the plurality of wiring layers laminated one upon another, a plurality of terminal patterns formed on the wiring layer for connections in a state insulated from each other, a plurality of vias for electrically connecting at least two of the plurality of terminal patterns to corresponding ones of the plurality of wiring layers, and connecting means for selectively connecting the plurality of terminal patterns to each other.

Abstract: A matrix switch board used for connecting and disconnecting a switching-system line and a subscriber line. The matrix switch board includes a board made of an insulating material, and first and second wiring patterns respectively formed on front and back sides of the board so as to cross each other. The matrix switch board further includes through holes provided at cross points of the first and second wiring patterns. In the matrix switch board, when a connection pin is inserted into at least one of the through holes, at least one of the first wiring patterns on the front side and at least one of the second wiring patterns on the back side are electrically connected to each other.
