Patent number: 5008489Abstract: An electrical cable is provided wherein a conducting member is surrounded by an insulator. Around the insulator is a shielding element which is configured such that a pressure sensitive or heat fusible adhesive is placed on a top surface of the shielding tape in a parallel, nested serpentine pattern. The shielding tape is positioned so that it surrounds the insulator and has an overlap of its top surface with its bottom surface. Due to the parallel serpentine adhesive pattern between the top surface and the bottom surface in the overlap, an effective seal against moisture is achieved, independent of the width of the individual adhesive strips. Similarly, contact between the metallic portion of the top surface and the metallic bottom surface achieves a barrier to electrical and electromagnetic interference within the electrical cable. The serpentine adhesive layer also functions to securely connect the shielding tape to the insulator.Type: GrantFiled: October 25, 1989Date of Patent: April 16, 1991Assignee: Facile Holdings, Inc.Inventors: Herman D.

Patent number: 4668581Abstract: Bonds between a contact area of a circuit of a semiconductor and a conductor are formed by applying a rotating tool to an opposed surface of the conductor or to an intervening material superposed on it. The conductor may be laminated to one or more layers of insulant material and when that material is for example polyester, the bond may be formed without prior removal of the insulant from between the contact area and the conductor; it is displaced by the effect of the tool. The areas and conductors may be in an array and the tool be brought across the members of the array in succession.Type: GrantFiled: January 22, 1985Date of Patent: May 26, 1987Assignee: Luc Technologies LimitedInventors: Penelope J. V. Luc, Patrick B. Ryan

Patent number: 4659872Abstract: A flat multiconductor cable having a multilayer construction and especially suited for use in establishing interconnections between the cable conductors and a separate conductive array such as a similar flat cable is disclosed. Conductive ink, formed metal conductors or etched conductors can be deposited on a flexible substrate and covered by a dielectric covering in the form of an ultraviolet cured dielectric coating or a separate insulating film. The conductors can be covered by anisotropic conductive adhesive with the conductive adhesive in contact with the underlying conductors at exposed tap locations where no dielectric coating is deposited or where the dielectric coating has been removed. A separate conductive array can be positioned in registry with the tap locations and the conductive adhesive can be used both to secure the conductive array to the cable and to establish electrical continuity between corresponding conductors.Type: GrantFiled: April 30, 1985Date of Patent: April 21, 1987Assignee: AMP IncorporatedInventors: Ronald A. Dery, William G. Gentry, Warren C. Jones, Clifton C. May, Jr., Steven G. Wentink

Patent number: 4642421Abstract: An adhesive interconnecting means is comprised of one or more conductors on an insulating substrate, a first adhesive layer, said first layer being anisotropically conductive and disposed over said conductors and substrate and a second adhesive layer said second layer being a flowable adhesive that extends over the first substrate and anisotropically conductive layer. The anisotropically conductive adhesive is comprised of a nonhomogenous mixture of conductive particles in a nonconductive adhesive binder; the conductive particles, of random size and shape, are dispersed randomly throughout the mixture in noncontiguous conductive units, each unit being comprised of one or more individual particles, the units being sufficiently spaced apart to preclude electrical conductivity between adjacent conductive areas on the same substrate.Type: GrantFiled: August 27, 1985Date of Patent: February 10, 1987Assignee: AMP IncorporatedInventors: Ronald A. Dery, Warren C. Jones

Patent number: 4640981Abstract: An interconnecting means is comprised of one or more conductive ink conductors screen printed onto a first substrate, the conductive ink being comprised of an insulating polymer medium having first and second groups of conductive particles therein, and an insulating layer of flowable adhesive in covering relationship to the conductors. The first group of particles are finely divided particles which are suspended in the medium and form a continuous conductive path along the length of the conductor. The second group of particles are agglomerates of large particles which are randomly scattered throughout the conductive path and project above the surface of the medium. Interconnection is effected by positioning the first substrate conductors in an overlapping conducting relationship to the conductors on the second substrate such that the flowable adhesive is deposited between the two substrates and applying pressure to the positioned conductors and surrounding areas.Type: GrantFiled: August 14, 1985Date of Patent: February 3, 1987Assignee: AMP IncorporatedInventors: Ronald A. Dery, Warren C. Jones

Patent number: 4596897Abstract: An electrical shielding tape comprises a polyester backing layer, and a metallic layer having an adhesive on the exposed surface thereof, the adhesive being disposed in an interrupted layer which defines both exposed open patches, or contact pads, and coated bonding areas thereon. The tape is constructed for use in a shielded cable of the type having at least one conductor wire and an uninsulated drain wire, wherein the tape is wrapped around the conductor and drain wires with the metallic surface of the tape facing inwardly and with the tape adhesively secured to the conductor and drain wires by means of the adhesive on the metallic surface thereof. Effective electrical contact between the tape and the drain wire is achieved in the open patches, or contact pads, which contact the drain wire, and therefore the tape can be grounded to achieve the desired shielding effects simply by connecting the drain wire to a ground terminal.Type: GrantFiled: March 12, 1984Date of Patent: June 24, 1986Assignee: Neptco IncorporatedInventor: Joel D. Gruhn

Patent number: 4578529Abstract: Process for manufacturing flat multi-conductor cable having two cable members and peelable internal lamina utilizes a pair of dies which simultaneously align conductors, laminate internal lamina, and extrude external lamina thereon. Each die has a conductor aligning surface with parallel linear conductor-receiving recesses therein and an adjacent extrusion surface. Conductors and internal lamina are drawn between aligning surfaces of mated dies and then between extrusion surfaces where vinyl is extruded through an aperture in each die to form external lamina. A knife-edged die insert adjacent one side of the aligning and extrusion surfaces provides a V-notch in one edge of the cable to facilitate peeling apart cable members for termination to a two-sided connector.Type: GrantFiled: August 2, 1984Date of Patent: March 25, 1986Assignee: AMP IncorporatedInventor: Raymond J.

Patent number: 4548862Abstract: Flexible tape having a pressure-sensitive adhesive layer containing particles, each particle having a ferromagnetic core and an electrically conductive surface. By virtue of the ferromagnetic cores, the particles can be magnetically attracted to form a large number of discrete electrically conductive bridges extending through the thickness of the adhesive layer. The tape can be used both to bond together and to electrically connect individual members of facing arrays of electrodes.Type: GrantFiled: September 4, 1984Date of Patent: October 22, 1985Assignee: Minnesota Mining and Manufacturing CompanyInventor: Richard B.

Patent number: 4546037Abstract: Individual electrical connections between two banks of electrodes can be made by the novel tape, a layer of which contains electrically conductive particles. Each particle has an electrically conductive surface and a ferromagnetic core by which the particles can be magnetically attracted to form nonintersecting stripes, each stripe containing a continuous array of contacting particles and hence being electrically conductive over both its length and thickness.Type: GrantFiled: September 4, 1984Date of Patent: October 8, 1985Assignee: Minnesota Mining and Manufacturing CompanyInventor: Timothy W.
