Abstract:
A semiconductor package having a plurality of electrodes arranged along one side of a rectangular semiconductor element; a plurality of wirings, one end of the wiring to be electrically connected with the electrode being arranged adjacent to the electrode and the other end of the wiring being exposed from an opening for external connection; a conductive member provided on the opening for external connection; a flexible wiring substrate on which the semiconductor element is mounted, and the wiring and the conductive member are arranged; and a sealing resin for sealing, except for the conductive member, the semiconductor element and a periphery of the semiconductor element. The semiconductor package can be connected in a horizontal or inclined condition with respect to the substrate for packaging by folding the flexible wiring substrate.
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.

Abstract:
In an SIP type module of the type wherein memory ICs are mounted to both surfaces of a substrate, the present invention provides a face package type memory module wherein packaging is made in an inclined direction in place of vertical packaging of the prior art technique and only the memory ICs mounted to the upper surface side of the substrate are deviated to the positions closer to the end portion of the substrate in order to drastically reduce the packaging height.
Abstract:
A connector is provided for mounting on a circuit board. The connector includes a body member and rows of first and second electrical contact pins coupled to the body member. The first contact pins are configured to extend downwardly below a bottom wall of the body member so that they align with the bottom wall to define an acute included angle therebetween. The second contact pins are configured to extend downwardly below the bottom wall in splayed relation to the first electrical contact pins and are aligned with the bottom wall to define an obtuse included angle therebetween. The first and second contact pins are made of spring material and cooperate to define a spring clip for yieldably drawing the bottom wall of the body member into seating engagement with the circuit board upon insertion of the first and second electrical contact pins into a pair of pin-receiving apertures formed in the circuit board.
Abstract:
A surface mounting method which utilizes an adhesive component to mount the electrical components to a printed circuit board instead of solder and which includes the use, between the contacting surfaces, of a flowable, corrosion-resistant material which bridges contact imperfections and penetrates surface films. The method may also be implemented to connect two electrical conductors.
Abstract:
A jumper wire material for connecting a pair of printed circuit wiring boards and having, in addition, a function to serve as a spacer for holding the printed circuit wiring boards in a mutually spaced relationship, the jumper wire material being constructed with core wires arranged in parallel with each other at a predetermined pitch, an insulative covering of a solid and non-flexible plastic material, and ridges projectively provided in parallel with each other on a pair of mutually opposed side surfaces of the insulative covering, and extending along the core wires.
Abstract:
A mounting substrate includes a through-hole 13 formed in a substrate 10, a first land part 21, a second land part 31, a first component attaching part 22, a second component attaching part 32, a conductive layer 14, and a filling member 15 filled into a part of the through-hole 13. A shortest distance allowable value L0 from the center of the first land part 21 to a component 51 is determined on the basis of the volume Vh of a part of the through-hole 15 positioned above a top surface of the filling member 15 on the side of the first land part 21, the length L1 of the component 51 to be mounted to the first component attaching part 22, and the maximum allowable value of the inclination of the component 51 to be mounted to the first component attaching part 22 relative to the first surface 11 of the substrate 10.

An assembly of a plurality of tiles (1) with a carrier (40), wherein the tiles (1) comprise a foil (20) with an electro-physical transducer (10) and electrical connectors (24, 28) to said transducer. The tiles are mechanically and electrically coupled to the carrier, and the tiles overlay according to a fish scale pattern.
Abstract:
A chip package includes an optical integrated circuit (such as a hybrid integrated circuit) and an integrated circuit that are adjacent to each in the chip package. The integrated circuit includes electrical circuits, such as memory or a processor, and the optical integrated circuit communicates optical signals with very high bandwidth. Moreover, a front surface of the integrated circuit is electrically coupled to a front surface of the optical integrated circuit by a top surface of the interposer, where the top surface faces the front surface of the integrated circuit and the front surface of the optical integrated circuit. Furthermore, the integrated circuit and the optical integrated circuit may be on a same side of the interposer. By integrating the optical integrated circuit and the integrated circuit in close proximity, the chip package may facilitate improved performance compared to chip packages with electrical interconnects.
