    Abstract: In a circuit board, when lands provided on a rear surface of a substrate are each separated into a mainland and a sub-land, warping or other defects of the substrate can be ignored when soldering, and the substrate can be mounted with a high bonding strength. On the rear surface of a module substrate, partitions are each provided to separate a metal film into the mainland and the sub-land. Accordingly, when the substrate is mounted on a motherboard, solder applied beforehand from each end-surface electrode to the mainland can be largely protruded downward from the mainland, and warping or other defects of the substrate can be ignored by this protruding portion of the solder. In addition, in the state in which the substrate is mounted, since the solder is pushed out from between the mainland and the motherboard and overflows the partition, both the mainland and the sub-land can be soldered to the motherboard side, and hence stable bonding can be obtained at a large bonding area.

    Abstract: A low noise clock oscillator in standard surface mount plastic or ceramic form. With the same soldering pads design such devices can be replace with a convention standard surface mount clock oscillator to reduce Electro-magnetic Interference or RFI (Radio Frequency Interference) without redesign of the main board. The oscillator is characterized by using a spectrum spread clock generator and a spread controller on an elevated platform to reduce common mode emission currents.

    Abstract: A ceramic substrate having two side surfaces in a lengthwise direction and two side surfaces in a widthwise direction intersecting each other. The ceramic substrate also includes at least one flat surface in a thicknesswise direction. Internal electrode films are embedded in the ceramic substrate with film surfaces thereof extending roughly parallel to the flat surface of the ceramic substrate. External electrodes are each provided on the flat surface of the ceramic substrate toward one of the two ends of the ceramic substrate in the lengthwise direction, are electrically continuous with the internal electrode films and are formed over distances and from the two side surfaces in the widthwise direction.

    Abstract: A connection structure of the present invention has a board with a through hole perforating therethrough, a land formed around the through hole, and a lead extending from an electronic component and disposed in the through hole. The land includes a wall surface land portion formed on a wall surface of the through hole, and front and back surface land portions formed on the front and back surfaces of the board respectively. A fillet connecting the land and the lead includes upper and lower fillet portions respectively contacting with the front and back surface land portions. A profile of the upper fillet portion is smaller than that of the lower fillet portion and is not smaller than that of the through hole. Therefore, occurrence of lift-off is effectively reduced while using a lead-free solder material.

    Abstract: A method and implementing computer system are provided in which de-coupling capacitors are used at driver and receiver sources, and defined gaps are created separating power and ground areas on a voltage reference plane of a circuit board. Short-circuit via connections are also provided through one or more vias between spatially separated circuit board layers. Each driver or receiver module includes the driver or receiver along with an associated gap, capacitor and via connections to VDD and ground planes, all included within a defined proximity to effectively block switching energy and/or VDD noise from entering the tri-plate ground-to-ground reference system. In a related exemplary construction, signal lines are placed at predetermined positions between ground planes to provide a tri-plate circuit board structure for transmitting logic signals from a driver to one or more receivers.
