Abstract:
According to the configuration and the manufacturing method of forming a moisture proof agent on both surfaces of a circuit substrate after soldering a capacitor connection pin in a vertical direction to the circuit substrate, and electrically connecting the capacitor so as to be in a perpendicular direction to the length direction of the capacitor connection pin at the upper space of the circuit substrate, the possibility of the moisture proof agent attaching to the capacitor is eliminated, the productivity enhances since the moisture proof agent can be easily formed on both surfaces of the circuit substrate, and a capacitor unit of miniaturized and low height configuration is realized since the capacitor is mounted in the horizontal direction in the upper space with respect to the circuit substrate.
Abstract:
A stand-off mounting apparatus includes an insulative carrier for off-board mounting of leaded or surface-mount components, particularly large temperature-sensitive discrete components such as capacitors. The carrier has a component-mounting surface that is elevated relative to the circuit board, and is positioned with respect to the circuit board such that the circuit board area under the mounting surface of the carrier is available for the placement of smaller non-temperature-sensitive components. The off-board components are mounted on the component-mounting surface of the carrier, and the carrier may include support features for providing additional mechanical support for the components. Electrical leads for electrically coupling the elevated components to the circuit board may be insert-molded in the carrier, or may be inserted into plated through-holes in the carrier.
Abstract:
A very small computer memory card is densely packed with a large number of flash EEPROM integrated circuit chips. A computer memory system provides for the ability to removably connect one or more of such cards with a common controller circuit that interfaces between the memory cards and a standard computer system bus. Alternately, each card can be provided with the necessary controller circuitry and thus is connectable directly to the computer system bus. An electronic system is described for a memory system and its controller within a single memory card. In a preferred physical arrangement, the cards utilize a main circuit board with a plurality of sub-boards attached thereto on both sides, each sub-board carrying several integrated circuit chips.

The wire retaining portion is configured to engage the lead wire to retain the lead wire in the second grooves.
Abstract:
A circuit board assembly has a flat coil element mounted on a circuit board so that an electric power loss is not generated even when the flat coil element is mounted to the circuit board together with a circuit part having a large heat sink. A module mounted on the circuit board has an electronic circuit device and a heat radiator attached to the electronic circuit device. The heat radiator has an extending part protruding from the electronic circuit device and extending parallel to a surface of the circuit board. A coil mounting area provided with no pattern wire is formed in a part of the circuit board facing the extending part. The flat coil element is mounted parallel to the circuit board in a state where a coil part of the flat coil element faces the coil mounting area.
