Abstract
Abstract A method of establishing relatively insulated connections between the ends of metal conductors arranged in a mounting frame and an insulating substrate, the substrate surface being provided with a metal coating and the conductor ends being secured to said metallized surface, after which the metallized surface is subjected to a process attaching the metal coating so that the metal regions located between the conductor ends are removed from the substrate.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
122 words
A method of producing an assembly comprising an electrically insulating substrate and a plurality of mutually insulated electrical connection elements thereon, said method comprising: a. providing a continuous metal coating on a face of said substrate; b. providing a sub-assembly comprising said electrical connection elements in spaced relation with respect to each other, said elements individually having conductor ends; c. electrically and mechanically securing said electrical connection elements at said conductor ends to said metal coating, said conductor ends covering only a portion of said metal coating and other portions of said elements projecting laterally from said coating; and, then, d. removing all parts of said metal coating except those located under the connection elements and masked thereby during the removal step.
Claim 2
Independent Claim
122 words
A method of producing an assembly comprising an electrically insulating substrate and a plurality of mutually insulated electrical connection elements thereon, said method comprising: a. providing a continuous metal coating on a face of said substrate; b. providing a sub-assembly comprising said electrical connection elements in spaced relation with respect to each other, said elements individually having conductor ends; c. electrically and mechanically securing said electrical connection elements at said conductor ends to said metal coating, said conductor ends covering only a portion of said metal coating and other portions of said elements projecting laterally from said coating; and, then, d. removing all parts of said metal coating except those located under the connection elements and masked thereby during the removal step.
Claim 3
Dependent Claim
30 words
A method as recited in claim 1, wherein said sub-assembly comprises said electrical connection elements extending in substantially the same direction and being individually connected to a surrounding frame member.
Claim 4
Dependent Claim
28 words
A method as recited in claim 1, wherein said step of removing comprises directing hard granular material onto the coating from a position located above the connection elements.
Claim 5
Dependent Claim
17 words
A method as recited in claim 1, wherein said step of removing comprises etching said metal coating.
Claim 6
Dependent Claim
14 words
A method as recited in claim 1, wherein said substrate comprises thermally conducting material.
