    Abstract: Electrical interconnection structures are described. The electrical interconnection structures are formed by electrically interconnecting in a stack a plurality of discrete substrates. By using a plurality of discrete substrates, a multilayer dielectric/electrical conductor structure can be fabricated from individual discrete substrates each of which can be tested prior to forming a composite stack so that defects in each discrete substrate can be eliminated before inclusion into the stack. Electrical interconnection between adjacent substrate is provided by an array of contact locations on each surface of the adjacent substrates. Corresponding contacts on adjacent substrates are adapted for mutual electrical engagement. Adjacent contact locations can be thermocompression bonded. To reduce the parasitic capacitance and coupled noise between the contact pads and the electrical conductors within the interior of each discrete substrate, the contact pads on each substrate have elongated shape. The elongated contact pads or lattice pads on adjacent substrates are nonparallel and preferably orthogonal so that the corresponding pads of adjacent substrates electrically interconnect an intersecting area which varies in location along the elongated contact pads as the placement of the adjacent substrates varies in the manufacture.

    Abstract: A surge protector or transient suppressors for AC power lines having its components mounted on a circuit board. The metalization of the board are configured to present as large a surface area as possible, given the topology of the board, to the flow of current. A return conductor is placed on the opposite side of the board with a large surface area corresponding to the first conductor. The magnetic field between the two conductors is substantially cancelled. This configuration reduces the magnetic field intensities associated with the flow of current, thereby reducing self-inductance.

The circuit patterns include a first signal pattern to be connected with one of the input pins, a first earth pattern connected with the other of the input pins, a second and a third signal pattern connected with one and another of the output pins, and a second earth pattern connected with the earth pin of the filter element. The first and the second signal pattern have end portions opposedly positioned to each other, and an earth pattern portion is positioned between the opposed end portions of the first and the second signal pattern to connect the first and the second earth pattern with each other. Portions of the patterns positioned beneath the filter element are arrayed symmetrically about an axis lying on the center of the terminal of the end portion of the first signal pattern and external between the second and third signal patterns.

    Abstract: One object is to compensate the reduction of the Q value due to reduction of core sectional area of a coil of an inductor, and the reduction of positional accuracy and adhesive strength of components mounted on a printed circuit board due to reduction of area of external electrodes, both caused by downsizing of component sizes. An inductor is provided which includes: a coil formed in an insulator and having one end and the other end thereof formed in a direction away from a mounting surface; and lead-out portions connected to the coil at positions more distant from the mounting surface than a portion of the coil closest to the mounting surface.

    Abstract: A printed circuit board (e.g., 103) includes capacitor elements (e.g., 121 and 122). The capacitor element (e.g., 121) returns a common mode current included in a signal output from a signal output terminal (e.g., 111) of a semiconductor element (e.g., 102), to a ground terminal (e.g., 113) of the semiconductor element (e.g., 102). The capacitor element (e.g., 122) returns a common mode current included in a signal output from a signal output terminal (e.g., 112) of the semiconductor element (e.g., 102), to the ground terminal (e.g., 113) of the semiconductor element (e.g., 102). The capacitor elements (e.g., 121 and 122) are arranged such that the mutual inductance between a parasitic inductance of the capacitor element (e.g., 121) and a parasitic inductance of the capacitor element (e.g., 122) for the common mode currents is a negative value. Accordingly, the effective inductances of the first and second capacitor elements for the common mode currents are reduced, which suppresses radiation noise.

    Abstract: The present invention proposes substrate material favoring via hole electroplating to overcome the conventional problem that the polymer-based printed circuit board is hard to conduct electricity and likely to have poor electroplating quality. The present invention adds a conductive material to a polymeric material and controls the proportions and structure thereof to form a substrate material so as to improve the affinity of the substrate material to the metal electroplated inside the via hole with the resistance of the substrate material remaining in an allowable range. Thereby is increased yield and efficiency and saved time and cost in fabricating printed circuit boards. Further, the present invention reduces the proportion of the polymeric material with the mechanical strength remaining in an allowable range so as to decrease the overall expansion rate and obtain a fire-proof effect. Therefore, the substrate material can be used to fabricate precision products.
