Method of making electronic circuit elements

Claim 1

THE METHOD OF MANUFACTURING A THIN, FLEXIBLE LAMINAR INSULATED CIRCIT BOARD OF DESIRED PATTERN, COMPRISING THE STEPS OF APPLYING TO ONE FACE OF A THIN FLAT, SMOOTH METALLIC BACKING SHEET A PLURALITY OF SEPARATE, SPACED-APART MUTUALLY INTERRELATED CONDUCTORS, AT LEAST SOME OF SAID CONDUCTORS HAVING A PLURALITY OF TERMINAL TABS LYING IN THE SAME PLANE AS THE CONDUCTORS AND FORMING A PART THEREOF, SAIDCONDUCTORS AND TERMINAL TABS COACTING TO FORM THE CIRCUIT PATTERN, APPLYING A COATING OF PLASTISOL OVER ONE SURFACE OF SAID METALLIC ACKING SHEET AND THE CONDUCTORS AND TABS THEREON TO ENCLOSE AND SURROUND THE ECPOSED SURFACES OF THE INDIVIDUAL CONDUCTORS AND TABS CARRIED THEREON, WHEREBY SAID CONDUCTORS AND TABS LIE WITHIN SHALLOW CHANNELS IN THE AFORESAID LAYER OF PLASTISOL, CURING THEPLASTISOL LAYER, WHEREBY IT BECOMES A YIELDABLE, PLIANT COVER SHEET, REMOVNG THE METALLIC BACKING SHEET FROM THE COVER SHEET AND FROM THE CONDUCTORS AND TABS BY ETCHING SAID BACKING SHEET ENTIRELY AWAY WHILE LEAVING THE INDIVIDUAL CONDUCTORS AND TABS EMBEDDED IN THE AFORESAID SHALLOW CHANNELS OF THE PLASTISOL LAYER, WITH ONE FACE OF EACH INDIVIDUAL CONDUCTORS AND TABS EMBEDDED EXPOSED IN A POSITION GENERALLY FLUSH WITH THE SURFACE OF SAID PLASTISOL LAYER, WHEREBY THE INDIVIDUAL CONDUCTORS AND TABS ARE SUPPORTED AND HELD IN PROPER ORIENTATION AND SPATIAL RELATIONSHIP TO EACH OTHER SOLELY BY THE PLASTISOL COVER SHEET, OVERLAYING THE FACE SURFACE OF THE PLASTISOL LAYER AND THE CONDUCTORS AND TABS POSITIONED IN CHANNELS THEREIN BY A THIN, FLEXIBLE, PERFORATED DIELECTRIC SUPPORTING SHEET HAVING AN OPEN HOLE OVERLYING EACH OF SAID TABS, ADHESIVELY SECURING SAID INDIVIDUAL CONDUCTORS TO THE ADJACENT FACE OF THE DIELECTRIC SUPPORTING SHEET WHILE LEAVING THE TABS FREE THEREFROM WITHIN THE AFORESAID HOLES, PEELING THE DIELECTRIC SUPPORTING SHEET AND THE PLASTISOL COVER SHEET APARRT TO WITHDRAW THE INDIVIDUAL CONDUCTORS AND TABS FROM THE AFORESAID CHANNELS IN THE FACE SURFACE OF THE COVER SHEET AND LEAVE THE CONDUCTORS ADHESIVELY SUPPORTED ON THE INNER FACE SURFACE OF THE DIELECTRIC SUPPORTING SHEET, APPLYING A SECOND THIN, FLEXIBLE, PERFORATED DIELECTRIC SUPPORTING SHEET ACROSS THE EXPOSED SURFACE OF THE CPNDUCTORS WITH A PERFORATION OF SAID SHEET OVERLYING EACH OF THE AFORESAID TABS, AD ADHESIVELY SECURING SAID FIRST AND SECOND SUPPORTING SHEETS TO EACH OTHER AND TO THE CONDUCTORS POSITIONED THEREBETWEEN.

Claim 2

THE METHOD OF MANUFACTURING A THIN, FLEXIBLE LAMINAR INSULATED CIRCIT BOARD OF DESIRED PATTERN, COMPRISING THE STEPS OF APPLYING TO ONE FACE OF A THIN FLAT, SMOOTH METALLIC BACKING SHEET A PLURALITY OF SEPARATE, SPACED-APART MUTUALLY INTERRELATED CONDUCTORS, AT LEAST SOME OF SAID CONDUCTORS HAVING A PLURALITY OF TERMINAL TABS LYING IN THE SAME PLANE AS THE CONDUCTORS AND FORMING A PART THEREOF, SAIDCONDUCTORS AND TERMINAL TABS COACTING TO FORM THE CIRCUIT PATTERN, APPLYING A COATING OF PLASTISOL OVER ONE SURFACE OF SAID METALLIC ACKING SHEET AND THE CONDUCTORS AND TABS THEREON TO ENCLOSE AND SURROUND THE ECPOSED SURFACES OF THE INDIVIDUAL CONDUCTORS AND TABS CARRIED THEREON, WHEREBY SAID CONDUCTORS AND TABS LIE WITHIN SHALLOW CHANNELS IN THE AFORESAID LAYER OF PLASTISOL, CURING THEPLASTISOL LAYER, WHEREBY IT BECOMES A YIELDABLE, PLIANT COVER SHEET, REMOVNG THE METALLIC BACKING SHEET FROM THE COVER SHEET AND FROM THE CONDUCTORS AND TABS BY ETCHING SAID BACKING SHEET ENTIRELY AWAY WHILE LEAVING THE INDIVIDUAL CONDUCTORS AND TABS EMBEDDED IN THE AFORESAID SHALLOW CHANNELS OF THE PLASTISOL LAYER, WITH ONE FACE OF EACH INDIVIDUAL CONDUCTORS AND TABS EMBEDDED EXPOSED IN A POSITION GENERALLY FLUSH WITH THE SURFACE OF SAID PLASTISOL LAYER, WHEREBY THE INDIVIDUAL CONDUCTORS AND TABS ARE SUPPORTED AND HELD IN PROPER ORIENTATION AND SPATIAL RELATIONSHIP TO EACH OTHER SOLELY BY THE PLASTISOL COVER SHEET, OVERLAYING THE FACE SURFACE OF THE PLASTISOL LAYER AND THE CONDUCTORS AND TABS POSITIONED IN CHANNELS THEREIN BY A THIN, FLEXIBLE, PERFORATED DIELECTRIC SUPPORTING SHEET HAVING AN OPEN HOLE OVERLYING EACH OF SAID TABS, ADHESIVELY SECURING SAID INDIVIDUAL CONDUCTORS TO THE ADJACENT FACE OF THE DIELECTRIC SUPPORTING SHEET WHILE LEAVING THE TABS FREE THEREFROM WITHIN THE AFORESAID HOLES, PEELING THE DIELECTRIC SUPPORTING SHEET AND THE PLASTISOL COVER SHEET APARRT TO WITHDRAW THE INDIVIDUAL CONDUCTORS AND TABS FROM THE AFORESAID CHANNELS IN THE FACE SURFACE OF THE COVER SHEET AND LEAVE THE CONDUCTORS ADHESIVELY SUPPORTED ON THE INNER FACE SURFACE OF THE DIELECTRIC SUPPORTING SHEET, APPLYING A SECOND THIN, FLEXIBLE, PERFORATED DIELECTRIC SUPPORTING SHEET ACROSS THE EXPOSED SURFACE OF THE CPNDUCTORS WITH A PERFORATION OF SAID SHEET OVERLYING EACH OF THE AFORESAID TABS, AD ADHESIVELY SECURING SAID FIRST AND SECOND SUPPORTING SHEETS TO EACH OTHER AND TO THE CONDUCTORS POSITIONED THEREBETWEEN.
