Abstract
Abstract An arrangement for terminating elements such as plated wire memory devices ( (which have the size of a human hair), wire resistor elements, or similar devices for connection to external circuitry. The arrangement is also suitable for coupling similar devices which are on different planes and are oriented either in parallel or at different angles. The arrangement includes positioning slots which serve as connecting lands as well as nonconducting walls to prevent short circuits between adjacent wires when molten solder is applied to the end of the wire.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
138 words
The method of fabricating a high density connecting device for wire devices comprising the steps of: a. forming a plurality of parallel grooves in a relatively thin piece of metal stock; b. filling said grooves with an insulating material; c. forming a first metallic coating which acts as a resist upon said stock except where said grooves are formed; d. adding a second metallic coating upon said first metallic coating with a thickness to form a plurality of current carrying conductors; e. fixing a substantially flat substrate over said second metallic coating; f. removing said metal stock from the underside of said grooves to expose the insulating material in said grooves and said first metallic coating so as to form insulating walls, the area between two contiguous walls forming a depressed land for connecting one said wire device.

Claim 3
Dependent Claim
18 words
The method of fabricating a connecting device in accordance with claim 1 wherein said metal stock is copper.
Claim 4
Dependent Claim
21 words
The method of fabricating a connecting device in accordance with claim 1 wherein said grooves are filled with an epoxy material.
Claim 5
Dependent Claim
32 words
The method of fabricating a connecting device in accordance with claim 1 wherein said first metallic coating is formed by electroplating a layer of gold everywhere except where said grooves are formed.
Claim 6
Dependent Claim
30 words
The method of fabricating a connecting device in accordance with claim 1 wherein said second metallic coating is formed by electroplating a layer of copper on said first metallic coating.
Claim 7
Dependent Claim
15 words
The method of fabricating a connecting device in accordance with claim 1 which is flexible.
