Abstract
Abstract Flexible wire cable and the flexible wire cable by the steps of the process for manufacturing the flexible wire cable. The flexible wire cable interconnects between two spaced plurality of terminals. The terminals can be equally centered at opposing ends or can be spaced on different centers at opposing ends. A plurality of wire conductors are laminated between two sheets of insulation, each sheet having a thermosetting polyester adhesive coating, which partially and fully cures as a function of time-temperature-pressure. Each of the plurality of wire conductors are substantially surrounded internally one hundred and eighty degrees by each sheet of the insulation. The insulation is offset to provide an overlap at opposing ends or at only one end to provide a solder stop and controlled flexings of the wire conductors. In another embodiment, at least one metallic shield is laminated to one side of the insulation sheet with like thermosetting polyester adhesive coating on the metallic sheet which cures as a function of time-temperature-pressure. A drain wire extends the length of the metallic shield and is tinned so that it is subsequently conductively bonded to the metallic shield.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
192 words
The process for manufacturing a flexible wire cable comprising the steps of: a. positioning wire conductors in a predetermined configuration; b. positioning a first sheet of insulation including a thermosetting polyester adhesive coating over said wire conductors; c. bonding said first insulation sheet as a first function of time, temperature, and pressure to said wire conductors and partially curing said adhesive; d. positioning a second sheet of insulation including a coating of said thermosetting polyester adhesive over said wire conductors and opposing said first sheet of insulation, said sheets forming an offset and overlap at one or both ends of said sheets; and, e. bonding said second insulation sheet to said wire conductors and said first insulation sheet as a second function of time-temperature-pressure and fully curing said adhesive whereby each of said wire conductors are substantially surrounded 180° by each of said adhesive coatings and said insulation sheets and channels are formed in said insulation sheets between each of said wire conductors and said offset end provides a solder stop and controlled flexing of said wire conductors thereby providing a flexible wire cable about the offset end and about each conductor.
Claim 2
Dependent Claim
192 words
The process for manufacturing a flexible wire cable comprising the steps of: a. positioning wire conductors in a predetermined configuration; b. positioning a first sheet of insulation including a thermosetting polyester adhesive coating over said wire conductors; c. bonding said first insulation sheet as a first function of time, temperature, and pressure to said wire conductors and partially curing said adhesive; d. positioning a second sheet of insulation including a coating of said thermosetting polyester adhesive over said wire conductors and opposing said first sheet of insulation, said sheets forming an offset and overlap at one or both ends of said sheets; and, e. bonding said second insulation sheet to said wire conductors and said first insulation sheet as a second function of time-temperature-pressure and fully curing said adhesive whereby each of said wire conductors are substantially surrounded 180° by each of said adhesive coatings and said insulation sheets and channels are formed in said insulation sheets between each of said wire conductors and said offset end provides a solder stop and controlled flexing of said wire conductors thereby providing a flexible wire cable about the offset end and about each conductor.
Claim 3
Dependent Claim
24 words
The process of claim 1 wherein said first function is pressure at one hundred p.s.i. at a temperature of 275° F. for one hour.
Claim 4
Dependent Claim
32 words
The process of claim 1 wherein said second function is pressure at one hundred p.s.i. at a temperature of 290° F. per hour, and subsequent cooling to a temperature of 150° F.
Claim 5
Dependent Claim
15 words
The process of claim 1 wherein said sheets of insulation are of different longitudinal length.
Claim 6
Dependent Claim
41 words
The process of claim 1 wherein positioning said second sheet of insulation forms an offset and overlap at both ends of said first insulation sheet whereby said offset and overlap provides a solder stop and controlled flexing of said wire conductor.
Claim 7
Dependent Claim
14 words
The process of claim 1 wherein said sheets of insulation are of equal lengths.
Claim 8
Dependent Claim
11 words
The process of claim 1 wherein said insulation sheets are Mylar.

Claim 11
Dependent Claim
16 words
The process of claim 1 comprising the positioning of said wire conductors in a fan-out configuration.
Claim 12
Dependent Claim
76 words
The process of claim 1 comprising: a. positioning a tinned drain wire the longitudinal length over at least one of said insulation sheets; b. positioning a metallic shield including said thermosetting polyester adhesive coating over said drain wire and said insulation sheet, and; c. bonding said metallic shield to said insulation sheet as a third function of time-temperature-pressure whereby solder bonding of said tined drain wires electrically bonds said tinned drain wire to said metallic shield.
Claim 13
Dependent Claim
23 words
The process of claim 11 wherein said third function is pressure at one hundred p.s.i. at a temperature 350° F. for one hour.
Claim 14
Dependent Claim
