Abstract
Abstract A flat, multilayer conductor sheet having a plurality of bonded or laminated layers of resin impregnated layers of material. At least one of the layers of material is provided with a plurality of parallel conductors extending in a first direction and at least another of the layers of material is provided with a plurality of parallel conductors extending in a direction transverse to the first direction so that a grid pattern of conductors is formed. Preferably a plurality of layers of material having conductors extending in a direction transverse to the first direction are provided with the conductors in the plurality of layers of material being all parallel to one another and arranged such that they do not overlie one another. Connections between the conductors extending transverse to one another are provided by forming vertical bores through the sheet which intersect the two conductors after which the bore is metallized so that a multiplanar conductor pattern may be formed. Vertical bores through the multilayer sheet may also be provided to interrupt or divide one of the conductors.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
120 words
A flat multilayer conductor sheet comprising: a plurality of parallel layers of resin impregnated material bonded together to form a multilayer structure, at least one of said layers of material being provided with a plurality of parallel conductors extending in a first direction, and a plurality of other of said layers each being provided with a plurality of parallel conductors extending in a direction transverse to said first direction, all of said conductors which extend in said direction transverse to said first direction being parallel to one another, and being arranged such that they do not overlie one another and form a pattern of consecutive conductors, whereby a grid pattern is formed between the transversely extending conductors of said layers.
Claim 2
Dependent Claim
120 words
A flat multilayer conductor sheet comprising: a plurality of parallel layers of resin impregnated material bonded together to form a multilayer structure, at least one of said layers of material being provided with a plurality of parallel conductors extending in a first direction, and a plurality of other of said layers each being provided with a plurality of parallel conductors extending in a direction transverse to said first direction, all of said conductors which extend in said direction transverse to said first direction being parallel to one another, and being arranged such that they do not overlie one another and form a pattern of consecutive conductors, whereby a grid pattern is formed between the transversely extending conductors of said layers.
Claim 3
Dependent Claim
24 words
A multilayer conductor sheet as defined in claim 1 wherein the conductors are insulated from one another by a dielectric material in said layers.
Claim 4
Dependent Claim
15 words
A multilayer conductor sheet as defined in claim 1 wherein said layers contain insulated conductors.
Claim 5
Dependent Claim
27 words
A multilayer conductor sheet as defined in claim 1 wherein an intermediate layer of insulating material is disposed between at least two of said layers with conductors.
Claim 6
Dependent Claim
51 words
A multilayer conductor sheet as defined in claim 1 wherein said arrangement is provided with at least one bore which extends through said layers and through a pair of conductors extending in directions transverse to one another, whereby, electrical contact may be provided between said pair of conductors via said bore.
Claim 7
Dependent Claim
48 words
A multilayer conductor sheet as defined in claim 5 wherein catalysts are impregnated in said layers which are released by the formation of said bore and sensitizes the walls of said bore so that a metal contact may be deposited therein without requiring the use of electric current.
Claim 8
Dependent Claim
67 words
A multilayer conductor sheet as defined in claim 5 wherein an intermediate layer of insulating material is disposed between at least two of said layers provided with conductors, and wherein said intermediate layer contains catalysts which, are released by the formation of said bore and sensitized the walls of said bore so that a metal contact may be deposited therein without requiring the use of electric current.
Claim 9
Dependent Claim
41 words
A multilayer conductor sheet as defined in claim 1 wherein the said surface of said arrangement is Coated with a layer of material containing catalysts which provide good adhesion between the material of said layers and an external metal conductor pattern.
Claim 10
Dependent Claim
36 words
A multilayer conductor sheet as defined in claim 1 wherein the spacing between said parallel conductors is such that a vertical bore can be formed through said layers which will interrupt only one of said conductors.
Claim 11
Dependent Claim
27 words
A multilayer conductor sheet as defined in claim 9 wherein said sheet is provided with at least one bore which interrupts at least one of said conductors.
Claim 12
Dependent Claim
22 words
A multilayer conductor sheet as defined in claim 10 wherein said bores which interrupt said conductors are filled with a dielectric material.
