Abstract
Abstract A method of making printed circuits which comprises passing a non-conductive strip of material past a device which repeatedly imparts a desired circuit pattern onto the passing strip so that a succession of identical printed circuit zones are created along the length of the strip. The strip is subsequently wound into a coil which can be stored for use as desired when printed circuit assemblies are to be fabricated. Fabrication of an assembly comprises unwinding the strip from the coil and severing of the strip between the individual printed circuit zones. A backing can be joined to the unwound strip before severing.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
144 words
A method of fabricating printed circuits comprising providing a conductive pattern producing means which can impart electrically conductive material in a given circuit pattern composed of a plurality of independent conductive paths, passing a strip of electrically nonconductive material in cooperative association with said means to cause said given pattern to be repeatedly imparted to separate successive zones of the strip thereby forming a succession of identical printed circuit zones separated from each other along said strip, and then coiling the strip to form a coiled supply of printed circuits for subsequent use as desired, and further including the steps of uncoiling the coiled strip and joining it to a more rigid backing, creating a desired hole pattern in each printed circuit passing through both the strip and the backing, and of severing the strip between successive zones to form separated individual printed circuits.
Claim 2
Independent Claim
144 words
A method of fabricating printed circuits comprising providing a conductive pattern producing means which can impart electrically conductive material in a given circuit pattern composed of a plurality of independent conductive paths, passing a strip of electrically nonconductive material in cooperative association with said means to cause said given pattern to be repeatedly imparted to separate successive zones of the strip thereby forming a succession of identical printed circuit zones separated from each other along said strip, and then coiling the strip to form a coiled supply of printed circuits for subsequent use as desired, and further including the steps of uncoiling the coiled strip and joining it to a more rigid backing, creating a desired hole pattern in each printed circuit passing through both the strip and the backing, and of severing the strip between successive zones to form separated individual printed circuits.
Claim 3
Dependent Claim
24 words
A method as set forth in claim 1 in which said means comprises means for imparting circuit patterns to opposite sides of the strip.
Claim 4
Dependent Claim
43 words
A method as set forth in claim 1 including the step of introducing a further strip in cooperative association with the first-mentioned strip before coiling so that said further strip separates individual convolutions of the first-mentioned strip from each other in the coil.
Claim 5
Dependent Claim
50 words
A method as set forth in claim 3 including the steps of uncoiling the two overlying strips from the coil and joining the first-mentioned strip to a backing while the further strip remains overlying the first-mentioned strip, and then removing the further strip from the first-mentioned strip after said joining.
Claim 6
Dependent Claim
36 words
A method as set forth in claim 1 in which said strip is pulled from a coil located forwardly of said means by a pulling force applied from a device in which the strip is coiled.
Claim 7
Independent Claim
111 words
A method of fabricating printed circuits comprising providing a conductive pattern producing means which can impart electrically conductive material in a given circuit pattern composed of a plurality of independent conductive paths, passing a strip of electrically non-conductive material in cooperative association with said means to cause said given pattern to be repeatedly imparted to separate successive zones of the strip thereby forming a succession of identical printed circuit zones separated from each other along said strip, and then coiling the strip to form a coiled supply of printed circuits for subsequent use as desired, and in which said non-conductive material is plastic and said conductive material is an electroconductive ink.
Claim 8
Independent Claim
111 words
