    Abstract: A wiring board is manufactured by a step of forming a meshy cylindrical body 2, where plural conductive rings 1 are connected to each other at plural positions in the respective peripheral direction, a step of forming laminated meshy sheets 3 and 4, by squashing the meshy cylindrical body 2 in the radial direction, a step of inserting an insulation sheet 5 between the meshy sheets 3 and 4, and a step of forming lacking portions 6 at a position in the peripheral direction of conductive rings 1a, 1b of the meshy sheets 3 and 4. It becomes possible to directly join a semiconductor chip 7 to the conductive ring 1a of the meshy sheet 3, and therefore, a wiring circuit can be obtained without using a solder joint.

Said method comprises the steps of providing a first circuit panel (544) having a dielectric body with oppositely directed top and bottom surfaces, contacts (538) on its top surface at locations of a first pattern, terminals (530) on its bottom surface, and through-conductors (527) electrically connected to said terminals and extending to the top surface of the panel, and a second circuit panel (562) having a dielectric body with a bottom surface and terminals (530) at locations of said first pattern on the bottom surface of such panel, said providing step including the step of customizing said first circuit panel by selectively treating the top surface of such panel so that less than all of the through conductors of such panel are connected to contacts of such panel; stacking said circuit panels in superposed, top-surface to bottom surface relation so that the top surface of said first circuit panel faces the bottom surface of said second circuit panel at a first interface and said first patterns on said facing surfaces are in registration with one another, with said contacts of said first panel being aligned with said terminals of said second panel at least some locations of said inregistration patterns; and non-selectively connecting all of said aligned contacts and terminals at said interface, whereby less than all of said through conductors of said customized panel are connected to terminals of said adjacent panel. The invention also relates to a multi-layer circuit assembly.

    Abstract: Electronic devices having at least two components (53,55) with mating contact pads (52,54) are provided with high-aspect-ratio solder joints between the mating pads. These joints are formed by placing a composite solder medium (51) containing solder wires (56) in an electrically insulating matrix (57) such that at least two solder wires (56) are in contact with the mating pads (52,54), and fusing the wires (56) to the pads. The insulating matrix (57) with remainder of solder wires (56) is then optionally removed from between the said at least two components (53,55). The composite solder medium (51) is formed by preparing an elongated body of solder wires in an insulating matrix and cutting off slices of the composite solder medium, the solder wires having a high-aspect-ratio of length to their diameter. Alternatively sheets of the composite solder medium are prepared by magnetically aligning solder coated magnetic particles into columns arranged transverse of an insulating matrix and heating sufficiently to fuse the solder in each column into a continuously conducting solder path.

    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.
