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 crystal oscillating device comprises an outer case having a longitudinal axis, a cavity, a pair of first surfaces extending along the longitudinal axis, a pair of second surfaces extending in a direction generally transverse to the longitudinal axis, a first opening portion in one of the first surfaces for providing access into the cavity, a second opening portion in one of the second surfaces, and a groove in the other of the second surfaces. A crystal oscillator is disposed in the cavity of the outer case and has lead terminals extending through the second opening portion of the outer case for electrically connecting the crystal oscillator to a circuit board. A bonding material is disposed in the cavity of the outer case for bonding the crystal oscillator to the outer case. A connecting member is disposed in the groove of the outer case for connecting the outer case to the circuit board.
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:
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 double-sided flexible electronic circuit module is provided having a flexible printed circuit board. The flexible circuit board has a plurality of conductive paths on each surface and a plurality of conductively plated-through apertures being connected to the conductive paths. One side of the flexible circuit board is adapted to carry components with leads; the other side of the flexible circuit board is adapted to receive components without leads. A carrier member, larger than the flexible circuit board and of a size and shape sufficient to accommodate the placement of at least one flexible circuit board, is also provided. The carrier member has a plurality of apertures which are in alignment with the apertures of the flexible circuit board, and a plurality of elongated slots in predetermined positions which extend the entire width of the flexible circuit board which is temporarily affixed onto the carrier member. All of the components are soldered to the flexible circuit board, the carrier member acting as a support member to the components having leads.
Abstract:
An arrangement for the mechanical fastening and electrical connection of a pellet, particularly a tantalum pellet, covered with a surface-adherent electrode, to a support. The electrode cannot be subjected to inertial forces of the pellet. An intermediate sheathing is positioned between the electrode and the support. The sheathing non-adhesively encompasses the pellet in a form-fitting manner. The intermediate sheathing is glued to the support. The electrode is electrically connected with the support through a flexible conductor element.
Abstract:
The invention relates to a holder for a button cell, wherein the holder is intended to be fastened on a printed circuit board, wherein the holder has at least two first latching arms which protrude from the printed circuit board when the holder is in the mounted state, wherein the button cell is received between the first latching arms when the button cell is in the mounted state, wherein the first latching arms, at one end, are each connected to a main body which has a base area which is connected to the printed circuit board when the holder is in the mounted state, wherein the first latching arms each have at least one first latching lug in order to hold the button cell on the printed circuit board, and wherein the first latching lugs are arranged at a first distance from the base area of the main body.
