Electrical interconnects having a supported bulge configuration
First Claim
1. An electrical connector, capable of establishing electrical contacts in flat circuits having line widths and spacing of less than 3 mil, comprising:
- a flat circuit having a smooth surface and including electrical conductors whose line widths and spacings may be less than 3 mil and which are encapsulated in dielectric material;
said conductors having sites defining positions of electrical interconnects and being free from said dielectric material on at least that conductor surface portion which is closest to the smooth surface of said circuit; and
a configuration, positioned at the sites, defining at least one ridge-like deformation extending across said circuit and both said conductors and any dielectric material contiguous thereto to define at least one ridged bulge in and across said conductors, for elevating those portions of said conductors and said dielectric material contiguous therewith and adjacent thereto at the sites above the smooth surface, and a support supporting said bulge being electrically, physically and chemically compatible with its surrounding materials.

Abstract
Electrical interconnects, contained in a supported bulge (42, 90) which extends substantially across a circuit or flexible cable (24, 92) in a continuous ridge pattern, are formed in both one or more of electrical conductors (32, 94) in the circuit or flexible cable and in any insulation (34, 98) underlying and adjacent to the conductors at the sites of the interconnects. The bulges may be placed individually in each conductor, or traverse the circuit or cable in a straight, curved, segmented or other broken or unbroken meandering path as a V-shaped or hollow shaped fold, wrinkle or crease in both the conductors and any insulation underlying the conductors at the sites of the interconnects. Supports (56, 108) for the bulges are so composed as to be physically, electrically and chemically compatible with their surrounding materials. Such interconnects are employable in circuits or flexible cables whose line widths and spacings are 3 mil (0.0762 mm) or less in dimension.

- 16. A method for providing electrical interconnects in a flat electrical circuit having a substantially uniformly smooth surface and electrical conductors which are sizable to 3 mil and less line width and spacing and are encapsulated in dielectric material, in which the conductors have sites defining the positions of the electrical interconnects and being free from the dielectric material on at least that conductor surface portion which is closest to the smooth surface of the circuit, comprising the step of forming supported deformations which extend substantially continuously across the circuit and in both the conductors and any dielectric material contiguous thereto for defining ridged bulges in the smooth surface at and adjacent to the sites in the conductors and any underlying and adjacent dielectric material for elevating those portions of the conductors, which are free from dielectric material, at the sites above the smooth surface.

17. A method for providing electrical interconnects in at least two flat electrical circuits, each having electrical conductors encapsulated in dielectric material and a substantially uniformly smooth surface, in which the conductors have sites defining the positions of the electrical interconnects and being free from the dielectric material on at least that conductor surface portion which is closest to the smooth surface of its circuit and the circuit adjacent thereto, comprising the steps of:
