Abstract:
The invention uses a programmable interconnect substrate having a plurality of conductive and interconnectable vias located on one or both surfaces thereof. A customised pattern of bonding pads is then formed over the one or both surface of the substrate which correspond to the terminal footprints of specific surface mounted packages intended to be mounted on the substrate. A generalised pattern of bonding pads may also be formed on the surface of the substrate for electrically connecting terminals of bare dice thereto by means of thin wire. All bonding pads are electrically connected to one or more vias by direct electrical contact or by a conductive trace extending from the bonding pad to a nearly via.
Abstract:
A printed circuit board which is of such a construction that patterns of electrically conductive strips and/or pads of either standard or non-standard form can be readily provided comprises a rigid board 1 of which at least the major surfaces are of electrically insulating material, which has extending through the board a multiplicity of holes 2 arranged in a pattern of rows and columns and which carries on one or each of its major surfaces a multiplicity of annular metal islands 3 each bounding a hole in the board and discrete with respect to the other annular islands. The rigid board 1 may also carry on said one or each of its major surfaces supplementary metal islands 4 and 5 each positioned between and discrete with respect to annular islands bounding adjacent holes in the rigid board. A circuit of either a standard or non-standard pattern can be formed by electrically interconnecting selected adjacent metal islands 3, 4 and 5 with local deposits of material of high electrical conductivity in such a way as to bridge the gap between adjacent islands. The local deposits may be effected manually but are preferably effected automatically using a modified computer aided design plotter or an automatic fluid dispensing machine.
Abstract:
A sheet material for providing electrical connections is provided which gives the needed degree of stability and low resistance with simplicity of application. Electrically conducted elements are dispersed in a polymeric layer and an adhesive is provided which is either the material of the layer or a coating over the elements which adhesive is non-tacky at room temperature but softens upon heating while reverting to a nonflowable condition on cooling. The electrically conductive elements can protrude above the surface of the polymer in which they are embedded. Electrically conductive layers can be provided over portions of the sheet with the polymeric layer containing electrically conductive elements extending over the whole of the sheet or over only those portions having electrically conductive lower layers.

A resin multilayer substrate includes a substrate main body including first, second, and third wiring portions connected to one another by a connecting portion. First, second and third external connection terminals are respectively included in the first, second and third wiring portions. The first external connection terminal includes a conductor exposed at a surface of the substrate main body. The second and third external connection terminals include connectors mounted on conductors on the surface of the substrate main body. An auxiliary mounting conductor is disposed between the first external connection terminal and the second and third external connection terminals on the surface of the substrate main body.

An example stretchable device is described that includes electrical contacts and an interconnect coupling the electrical contacts. The interconnect has a meander-shaped configuration that includes at least one nested serpentine-shaped feature. The interconnect can be conductive or non-conductive. The meander-shaped configuration can be a serpentine structure, providing a serpentine-in-serpentine configuration.

A capacitor includes a dielectric substrate and a large number of filamentous conductors formed to penetrate through the dielectric substrate in a thickness direction thereof. An electrode is connected to only respective one ends of a plurality of filamentous conductors constituting one of groups each composed of a plurality of filamentous conductors. The electrode is disposed in at least one position on each of both surfaces of the dielectric substrate, or in at least two positions on one of the surfaces. Further, an insulating layer is formed on each of both surfaces of the dielectric substrate so as to cover regions between the electrodes, and a conductor layer is formed on the corresponding insulating layer integrally with a desired number of electrodes.
